I need some help. Last week my engine and battery light came on along with drop on the voltmeter. Eventually the bike died and I had to push it home. I replaced the battery as it was very dead now and it was 2 years old. Probably due for a battery. After replacing the battery I checked the stator output and it checked out good.
This morning I went for a ride. After about 30 minutes the voltage dropped down to 10 on the meter so I turned around and came back home. After letting the bike sit for an hour or so I started it up and the voltage is back up.
t sounds like the voltage regulator but I don't know how to check it and be sure before I spend $200 for a new one.
Anybody help with that??

check the wires going into the case for your stator it could be it heats up and looses contact cold its charging hot it expands and discharges

 

Mine did that it was the voltage regulator . It also spiked the volt gauge one time,everything put out a over voltage code.

 

One more thing to check is the main power coming from the battery/main circuit breaker, feeding the fuses. I had a bad connection there and it caused the voltage to drop.

There is a method for checking the voltage regulator that involves checking the continuity. Good luck
