1997 Yamaha gas over voltage issue
Hello BGW, I have a 1997 yamaha gas that is over charging the battery. I replaced battery,and I have replaced voltage regulator 2 times and also put a new starter/generator on it. At about 30% throttle I am getting 17 plus volts at battery. Can anyone lead me in the right direction here??? Help

I get 0.137 when I check it from battery negative to black wire at at regulator. Regulator is connected and this new generator is an advanced brand unit. Regulator is aftermarket market,but I have tried oem also with same result. Battery is brand new flooded style.

I did just find a black wire that comes off the negative battery terminal then has a butt connector that was unplugged. Plugged it in and still get high voltage.

I was just about to post when I noticed that CP241 linked to my thread from last month.
I did all the checks for opens, shorts, current leakage that CP241 helped me with. In the end I gave up and am just driving it. I really wish I had checked (and wrote it down) the voltage I was getting over previous years. I suspect it's been over charging since it left the factory. But, after having several dealer mechanics tell me that that is sorta normal for Yamaha's I'm moving on but will keep an eye on how long the new battery lasts. |

Make sure the black wire is grounded on the vr if you haven’t already done that.

I've been thinking of trying that with my cart but have been hesitant to cut off the factory connector. Would be easy enough to do though.
