Yamaha G2 battery drain
Hello,
I have a Yamaha G2 that is getting completely redone. Its already been lifted & has bigger tires with more to go, however I still have a battery drain problem I have yet been able to pinpoint. There is a slow draw on the battery even with the key switch turned off. It drops from 12.7 to 11.8 and so on by morning and keeps dropping. I have a brand new battery. I have already replaced the voltage regulator & starter solenoid. I have traced the electrical system and have re-wired a lot of connections that were not done correctly from who ever had it last. I have checked after installing the voltage regulator that it is charging correctly. When the engine is running max voltage is 16.3, I'm assuming that is ok. My next area of question is the starter generator, can this cause a slow battery drain if its bad? I'm hoping someone has had a similar problem, any input would be great! |

Re: Yamaha G2 battery drain
Just replaced starter generator with new. So far have replaced starter solenoid, generator, voltage regulator and still have the same slow draw even with key turned off.
I have checked and cleaned the positive battery terminals. Brand new battery. Everything runs great, except for battery draining after a few days. Any other thoughts on what the issue could be? |

Re: Yamaha G2 battery drain
You should use a meter to determine the current draw and the unplug things one by one until you find the thing causing the draw. A bad battery will also self discharge.
