When your Yamaha Ignition Relay for G16, G20, G21, and G22 models starts to go faulty, it can be like a slumber party gone wrong. A first, it will work fine, just like when all your friends arrive to marathon watch your favorite show. Then things start to get intermittent. The spark will come and go. This causes the cylinder to preload. If that happens, you will get a backfire that sounds like someone shooting a firework off under your carriage. Very similar when those two friends who don't like one another start to bicker. It's only a matter of time before the sparklers get ignited.
The stock relay on your Yamaha will eventually quit altogether. This is normal as they are only good for about 50,000 sparks before they start to give issues. It can be like a vanishing trick. One minute you are cruising down the road, and the next, your performance just disappears out of nowhere. Hopefully, you will be fortunate enough for this to happen near home. Having a caddie towed is not a cheap endeavor. This is why we recommend replacing the Yamaha ignition relay as soon as it starts to give you problems. So if it sounds like independence day or New Year's is following you around town, let's get it replaced before riding you are riding shotgun in a tow truck.
This golf cart part is not hard at all to replace. We would highly recommend having a buddy there to help. Anytime you are doing anything with electricity, you should have a spotter. If you are smart about it, you will convince them to install it while watching their back. Maybe you are crazy like us and like this kind of thing. Whatever your methodology, call Buggies Unlimited for the best deal on what you need.
That is a great question! This could very well be causing the issue. It could be a few other things as well. Things like the stop switch, key switch, solenoid or a few other things. All can easily be tested so you know you are buying the right part to fix the issue the first time. Please give me a call, 888 444 9994 ext.3 for tech support. Have a volt meter handy and be close to the golf cart. We will figure it out together!
to supply power to the ignition system
Yes it could be. Be sure to check all grounds and try a ground from the engine to the battery to make sure there is not issue there. Those relays will weld themselves internally.
my problem was I got no response when I hit the gas peddle. This part resulted in my cart starting right up. I found this was my problem when I unplugged it, and used a wire to bypass the relay and it started.
More than likely its not the igniter, you have a dead short to ground, I would start at the start stop switch under the gas pedal
My G22 is second hand and rebuilt by the former owner. I do not have a white wire at the front of the engine. Seems like you have a short somewhere, check for frayed or pinched wires.
It will not.
It will be $91.95 plus shipping and sales tax.
