Hi guys I am having trouble with over voltage.
with lights on voltage stays at 13.8 with out lights on 16.5
What would be that problem Regulator? if so how do I check it.
It sounds like either you battery is dead or the regulator is bad. I had this experience with my 500. The way their regulation system works is that it need a constant 12 volts in from the battery to run, otherwise the current from the coil is sent directly to the bike's systems. I had a dead batter and had to pull start is, as I started riding I turned on my lights, they were bright blue like xenon lights for a second then they burned out. After doing some research and talking to dealers I found out of the design flaw in their regulators.
To test it make sure with the atv off that the battery has around 12 volts. The only other thing to check, is make sure that the bullet connectors that connect the wiring harness to the regulator are connected, also you could try unplugging them then plugging them back in.
Hay guys thanks, One the Battery has checked out ok and will take a charge and will hold voltage after the charge. I do not know how the Voltage regulator would go bad but it is after all just a part. Where do you get a used one? Or just pay Polaris the 125 for the Dam thing.
Should I replace the Battery at the same time?
I always thought that when a Voltage reg went bad it did not charge not over charge, But if a lot of guys are having trouble with the same item does Polaris have a recall on this?
It's not that it is overcharging the battery, it is not regulating the raw power coming from the magneto, and all that power is going to the atv's system which is not designed for anything over about 12 volts.
