Yamaha G1 starter generator test
Just throwing this out there for anybody like me that didn't know how to test a starter/generator. This is how I tested mine and there may be other ways to do it, but this ended up being pretty simple.
First off there are 4 posts on the starter each should be stamped A1, A2, F1 and F2 as in the diagram above. There should also be a green wire and a red wire coming out the side of the starter. I disconnected all cables and wires prior to testing. Connect post F2 to the positive terminal on your carts battery and A1 to the negative terminal. Now if you connect A2 directly to F1 your starter should spin forward. For reverse connect F2 to positive terminal of battery and A2 to the negative terminal. Now if you connect A1 directly to F1 the starter should run in reverse. The last thing I did was check the Ohms running through the red and green wires. To do this use a voltmeter set to Ohms (looks like an upside down horseshoe symbol) touching the green wire with one probe and the red wire with the other you should read about 5 Ohms. Hopefully this will save you some time if you were wondering if your starter was bad. Took me a while to figure out on my own without a repair manual. |

Re: Yamaha G1 starter generator test
That is the proper test, except the voltage, if the regulator is ok, should be 14.5-15.5 Volts. 17 volts would indicate a bad VR. - RAY

Re: Yamaha G1 starter generator test
Just my opinion and years of experience with batterys, generators, Dc motors, and charging systems. What ever happened to using an ammeter to check charging current? All battery chargers read in amps. So why are we just looking at voltage as the reference? You can over charge a battery on just 3/4 of an amp. Not very noticable on a cheap volt meter. There are some very nice shunt reading ammeters available on the market.

Re: Yamaha G1 starter generator test
I was just about to try this test because my cart stopped running unexplainedly, but I decided to check my connections first and I found an old quick disconnect connector I didn't like. I had no loose connections so I replaced all of my terminal rings and the cart started and ran great.
I popped off the dust cover to check my brushes and they looked ok so after all of the lurking around this forum I've learned a lot about electrical work and my cart. Thanks all! |
