Your golf cart's battery is a very hardworking group of cells. There are all kinds of things that it is responsible for, like getting the golf cart running, maintaining basic systems, and running all of your accessories. It's no wonder that if your Yamaha Reliance Starter Generator is such an important part. Sure the battery gets the starter side of things running and actually starts the engine. Once it is running, however, the generator side of things takes over and starts to recharge the battery. You can imagine that if you lost either side of its functionality, you would be dead in the water. If it can't start, there is no way it's charging, and if it can't charge, it may start, but it will not stay running for long.This golf cart starter is not a hard part to install. It can be a little heavy and awkward at times, so having a buddy there to help is a great idea. Ask about a Yamaha OEM service manual today when you call Buggies Unlimited to place this order. I will go a long way in helping.
