'06 FS650C converted / Burns headlight bulbs!

RE:

Where did you buy your stock parts and how much did they charge you for them? What are you doing about the kick stand. Sorry I can't hlelp with the problem...

I had the same problem and when I measured the voltage, found it increased with rpm's to the point it burned out the bulbs. The fix is well documented and involves sending your stator unit to Trailtech in Oregon for a rewind, common ground connection and a rectifier install. Price is very reasonable and service great. Call them to get details. Once you do this, you'll have enough stator wattage to run your lights and recharge your battery.

What are your voltage readings at the battery when the bike is running at low-mid rpms?

Stator/Rotors typically output 60volts A/C. This power is routed to a voltage regulator/rectifier which converts in into 14.4volts D/C.

Greetings,

Your lighting system is A/C, and there is a rectified D/C system for charging the battery.

There are a few possiblities here:

#1 Your regulator is not grounded, and thus has no where to shunt the extra Voltage and that is why your light bulbs are burning out.

Or, #2, your voltage regulator is no good.

Typically, the electrical system, lights and battery, is grounded to the frame at one or more points to the frame, as well as the battery. And I think this might be the missing link as you have not mentioned putting the starter or a battery in it. If memory serves the ground from the regulator goes to the ground or negative on the battery which is then connected or grounded to the frame. And if you do not have this connection to a battery that would explain why you keep over voltaging your a/c lighting system.

What do you think?
