Yam G9 runs fine but doesn't charge
I have a G9. Brand new battery and it keeps gradually draining. I always keep the key off when parked and have no lights etc. I charged the battery back and then it will stay charged for 3-4 days but then will die. I figured something has to be draining it or maybe the starter generator is not charging it back?? Any way to check if the starter generator is charging?

Re: Yam G9 runs fine but doesn't charge
The testing procedure has been posted many times before here, but I can tell you the small wires on the generator are for charging, and the voltage regulator is on the rear fender as is a couple fuses (opposite the clutches). Check the fuses and wiring to each before you do anything. Fuses and wiring problems are common in these old carts, but that is good because its cheap to fix.
This should be similar: http://www.buggiesgonewild.com/gas-y...runs-down.html And the wiring diagram should be in a sticky post above. In general put a DMM meter on the battery and it should charge at fast idle and raise the voltage a little. If not test the generator, if that is good and fuses are good/etc then odds are the voltage reg is bad. Edit: Smallblock beat me to it anyway lol. |
