CS (JulAug13) - Excel Tire & Wheel


Excel develops niche product for its customers and this Street Fox is a perfect example. We developed this exclusively for Nivel in many sizes to show the competition where the golf cart tire business is heading and to be the leader of the pack.

Street Fox – This brand new design is made in a radial casing so the handling and ride comfort is the top of the field. The special tread design and rubber compound makes the tire quieter for on road usage, and it looks cool. Also it is DOT approved so you can legally drive the golf cart on the road and if your golf cart can go 62 mph than this tire is for you because it is rated for this top speed. The last thing that is very special is the rim protector and how it will save those expensive rims if you rub a curb.

ATG (JulAug13) - Can I remove my governor?

QUESTION: SE from Texas writes: How can I get rid of the governor?

ANSWER: That is a common question. I do not suggest the removal of the governor and will not offer how to disconnect it. However, I will tell you how it works and how to adjust it. The governor is there for a reason. And that is to protect your engine from a over “rev” resulting in damage to engine or operator. For me to tell you to remove a safety devise I cannot.

The governor on gas golf cars works off centrifugal force or mechanical force and is usually located in the Drive unit. A balancing act occurs as engine RPM is raised causing pressure against an external spring. Pressure and spring tension cause a restriction in engine top RPM’s (Revulsions Per Minute). By increasing this spring tension we can raise the RPM level. By decreasing the spring tension we lower RPM level. This is all based on a working set of linkages and throttle adjustments. Meaning it is key to have complete throttle opening as well as closed idle settings. If you never have full throttle how can you ever have full power! So at engine off you need to check for full throttle down with accelerator and check the opening of the throttle plate. With the accelerator pedal fully up you should see an at rest of the throttle plate against the idle adjusting screw. Kind of think of it as you would a potentiometer as a position from at rest to full wipe. Once you have made all the proper throttle open and closed positions then you can adjust the governor. That is the number one part of governor adjusting that is often missed. Each manufacturer has top governor settings listed in their service manuals so refer to that for correct settings.

Common question two is tied into this same question as above. “My gas powered golf car does not have any power”? As you can see the governor and throttle opening has a lot to do with power. Based on those settings being correct then we move on to other area’s of power loss.

1) Low compression can be a source of lost power

2) Intermittent spark can be a source of lost power

3) Water in the fuel system can be a source of lost power

4) Air leaks or vacuum leaks can be a source of lost power

5) Mechanical “drag” such as brake drag, tire pressure, wheel alignment ETC….

6) Charging system that is always in full charge mode

7) Restricted exhaust

8) Wrong drive belt

9) Drive clutch filled with dirt and debris

10) Driven clutch spring or sheave movement wrong or broken

11) Drive or driven clutch sheaves worn out restricting belt movement

As you can see from this partial list it is never just a cut and dried one answer of area sort of thing. There are multiples and you have to follow procedure to recognize or find the exact cause. But from experience the most common cause is failure to have full throttle and or air leaks. Briefly air leaks (vacuum leaks) can be in the air cleaner box, hoses, carburetor mounting, or throttle shaft. I am not saying to jump directly to those area’s I am just saying that is most common. Just do not rule out the other area’s and look for quick fixes.

If all is well you can always add torque gears or driven clutch torque spring for added power. This eliminates the need for drastic changes like governor removal.

TS (JulAug13) - AC Motor Drive Systems

By: Matt Vallez

Over the last several years we have seen the increased use of AC systems in golf cars. The most telling development has been E-Z-GO installing an AC system as standard on their RXV golf car. In past articles I have highlighted an AC system for golf cars and discussed its advantages. Well, it is here to stay and there are some big improvements. Whether golf cars are your profitable business, your dependable local transport or your enthusiastic hobby, you want the best performance you can get. With AC induction motor technology, you can get more, much more. But that doesn’t mean you have to go out and buy the newest generation golf cars that come straight from the manufacturer with today’s latest AC motor/controller systems installed. Instead, get one of the new AC Conversion Kits that let you upgrade your existing car, and get the most out of your vehicle investment.

What’s the AC Advantage?

Just a few years back, AC motor drive systems were the new frontier in EV technology, building on a progression of Series and SepEx® motors. Today, they’ve been proven – in every usage application and environment – to deliver more performance and programming than DC generations past and present. The advantages are considerable:

Efficiency: When correctly configured, AC systems do a better job of converting electrical to mechanical energy.

Speed: Not only can an AC system achieve higher speed, it also has better power characteristics at higher speeds.

Maintenance: AC’s brushless technology puts a lot less wear and tear on the motor, thus requiring less maintenance.

Simplicity: Construction of the AC motor is much simpler, another maintenance plus.

For many fans of AC EV technology, drive quality is the overriding factor. If you’ve ever driven an AC golf car, you can’t help but notice the exceptional difference. The system is more controllable, accelerates more smoothly, transitions forward to reverse more smoothly, and overall delivers more feeling of control with less drag.

The power issue is also significant: high efficiency translates to longer battery life so the golf car goes further on the charge. And with the improved torque of today’s AC systems, these cars become faster and more rugged. They can actually be modified for all-terrain use, to go up hill and through rocky terrain. Hunters and outdoor enthusiasts take note … there is definitely an increase in torque.

One more point – an uncommon occurrence but still an important advantage: In the rare event of a failure, an AC system failure mode brings vehicle safely to a stop.

Package Deal: AC Conversion Kit Contents

Nivel Parts LLC has a new AC System Conversion Kit on the market that has everything you need to successfully implement a conversion. The comprehensive kit includes these components:

Activation wiring harness

Power cables for the motor to controller connection

Inline fuse for power circuit


Dash Display Meter

AC drive motor

Wiring diagramming instructions

Curtis AC motor controller (500 amp)

Nivel created this kit after observing how long a well-kept golf car can stay in circulation. “It’s not hard to keep the body in good condition, especially since most golf cars are not out in severe weather,” says Roger Kramer, an Engineering Manager at Nivel. “The chassis often remains in great condition even as the motor and drive system become outdated. We started thinking what we could do for our customers who want improved performance but can’t see their way clear to replacing a good, solid vehicle. This way, they don’t have to replace the whole vehicle – they can get a new high-performance electric golf car for the cost of the kit.”

Industry News - July/August 2013


Bubba Watson teamed up with sunglasses maker Oakley and a hovercraft company in building the futuristic cart, which can go over water, sand and greens without damaging any surface.

Neoteric Hovercraft in Indian builds crafts for recreation, rescue, commercial and military customers. New ones are offered for about $65,000, but refurbished models can be had for about $15,000. Engines range from about 50 to 100 hp, some use Hirth motors and others use Fuji.

The first challenge, according to Fitzgerald, was to incorporate what you need from a golf cart into the hovercraft. The video shows Fitzgerald and his team fabricating parts for the machine.

“The big advantage of the hovercraft is that it has a footprint pressure about 30 times less than the human foot,” says Fitzgerald, “so that by hovering across a green you leave absolutely no trace.”

Watson says he gets a lot of stares and laughs, but once people see how efficient it is, they want to drive it and forget all about playing golf.

As National Lightning Safety Awareness Week (June 23-29) approaches, the good news is the number of lightning-related deaths in the U.S. is on the decline. But that shouldn’t be a sign for course operators to lessen their efforts to educate golfers about the dangers of lightning while on the course.

An average of 35 fatalities was recorded by the National Weather Service (NWS) over the past decade (including a record low of 26 in 2011), a 33 percent reduction over the previous 10-year period. From 2006 to 2012, eight lightning-related deaths have occurred on golf courses.

“Of course, even one death is too many, and that’s why golf course operators have a responsibility to be diligent about the safety of their golfers,” says Robert Dugan, president of Thor Guard, the leader in lightning prediction and warning systems for golf courses.

Dugan said operators can uphold that responsibility through a combination of education and technology.

“A lot of people just don’t understand how dangerous lightning really is. They don’t realize it could be 100 million volts of electricity coming at them faster than they can blink an eye,” he said. “Operators need to continually remind players of the dangers and adopt a strict policy regarding play once a lightning warning has been issued.” Dugan, whose Thor Guard systems are in place at some 1,500 courses in the U.S., said course operators must be “absolutely sure the people using your facility know what it means when the horn (signaling a high lightning probability) sounds and know exactly what to do.

“Communicate any way you can, including with signs and starter’s instructions,” he says. “Only the most sophisticated technology can predict a lightning strike. Your body can’t predict it. So when the system goes off, you have to believe there’s a reason it went off and you should react immediately.”

The downward trend in lightning-related deaths is attributed in large part to more golfers hearing and heeding the warnings, said NWS meteorologist John Jensenius, who initiated the first National Lightning Safety Awareness Week in 2001. “The message is very simple: If you can hear thunder, you can be struck by lightning and you need to go indoors immediately,” Jensenius said.

Thunder is certainly a strong indicator of severe weather, but the vagaries of lightning include the proverbial “bolt out of the blue,” which comes without warning. Advances in technology, such as Thor Guard’s lightning prediction and warning systems, can help educate golfers while giving operators, their staffs and golfers early warnings of severe weather.

Thor Guard’s ThorPCX software gives course operators, members and guests access to accurate weather conditions and timely forecasts. And thanks to the new ThorMobile system, the data is available through mobile devices such as smart phones and tablets, so golfers can monitor severe weather data from the course or practice range.

There’s no excuse for getting lost at the Cranberry Highlands Golf Course in Cranberry. Their golf carts are equipped with GPS. But distances are measured not in streets, but fairways. Golf course supervisor Craig Walker says Cranberry Highlands is the first in the area with the 2013 model.

“They actually came out with a walking GPS device,” he says, “and located every trap, the contours of the green, the tees. Every feature of the golf course is located on here in that picture. It’s great. It tells you how far it is to different bunkers on the course. So it does give you exact yardage to help plan your next shot. And those constantly change as you move the golf cart.”

He uses a par 5, 507-yard hole as an example. “I know I have to hit it at least 258 yards to get past that bunker,” he said. “Or I can just lay it down the middle, like normal and have my normal second shot.”

But will old school duffers take kindly to this golfers positioning service? “We do have some people it takes a bit longer to get used to,” Walker said. “Their first time, yeah, they have a little problem with the technology. But we found by the second or third round they fall in love with it, just like everyone else.”

Bluebirds are attracted to the tall fescue grass, planted in cooperation with the Audubon Society. But don’t try to drive one of those carts into that grass. The GPS will stop you, right in your tracks.

It even seems to know when you’re hungry.

“All they need to do is touch the screen,” Walker says. “That’ll go directly to the menu. So if I want a Philly steak and fries, I can just add that to the order. And that order will be ready for me in about 20 minutes.”

Eventually, he hopes, the GPS will even find lost golf balls.
