I have been trouble shooting my 04 800 rev with no spark. Stator puts out 3 volts AC between all 3 wires. and I am getting voltage out of the regulator, but nothing at the coil wires. Would the pick-up coils cause this? or could the MPEM be bad?? such an expensive part to buy and try without any testing. Just wondering if anyone has had problems with this part. I appreciate any input.
