My í83 XT550ís rectifier/regulator is faulty. I donít know in what way, but there is no voltage over the battery.

If the rectifier/regulator failure results in too low resistance the stator probably will burn (too much current).

If I disconnect the rectifier/regulator the voltage will go up, but how high? Is it possible that the voltage will go high enough to destroy the isolation?

Zecatfish, thanks for the info. I have enjoed reading about your work on your XT, good stuff. I have not yet tested the DIY CDI since I donít know excaclty how the stator will react if I disconnect the rectifier unit, and since I donít know how much current the stator is pumping out now, I donít what to run the engine for more than couple of minutes at the timeÖ.
If you just unhook the reg/rectifier and leave the wires open it should not hurt anything and run it off the battery.

The XT is a three phase stator. You need to keep that in mind if you go aftermarket on the reg/rectifier. I wish I could help there.
PM Big Ed XT Fan he might have one.
