Can a shorted stator be repaired. the wires entering the stator are OK.
Does the flywheel come off easy enough to take a quick look at it?
After inspecting and testing the charging system I found a defective rectifier. So like an idiot I installed the new one and fired up the motor. No charge, same story. I removed and tested the diodes in the new rectifier and they appear open. The stator seems intact at 1.2 ohms but the yellow/Grey side is shorted to gnd. The red + wire is good to the solenoid post (batt).
Looking at the construction of a bridge rectifier with the stator taps grounded, there shouldn't be current through any of the diodes.
Only a reverse battery connection should over current the diodes. Worst case is if an opposite pair of diodes went the stator would have 12 amp through it possible melt some insulator material allowing a short to the engine block.
Trying to do a weekend lake trip tomorrow and may have to just go without a charging system.
