Does anyone know the resistance spec on the stator for a 446?
I have zero between either of the two output wires and ground, but across the 2 output wires it reads no resistance. (like i was to put the two DVM leads together) Is this stator fried? I never had it on the engine and would like to save some time by determining if its good...
Thanks,
Andy

Do engine running test on 2 wire from stator set meter to 0-50 VAC test 2 leads see what VAC output voltage is check engine speed at full throttle transaxle in neutral safety first. output rise with engine rpm's if get 25 VAC good stator range volts can go from idle 10 VAC to full throttle 35 VAC. Engine needs 3600 rpm's to reach 25 to 27 VAC common. I know have problem with charge and not charge that not in stator does not intermittent the meter set to 12 VDC traced back battery or battery to regulator help find problem at connection points wires switch gauge.

Your first test proved that the coil is not shorted to ground......meaning the laminations the coil is wound on. That's good news. The second test shows that you have continuity....meaning that the coil is not "open" due to a broken or burnt-off wire. i don't know if there is a OHM reading on these stators but if there is, it would be pretty low. Based on your tests, I would form the belief that the stator is just fine and well worth hanging onto. :thumbsup:

As Gator pointed out, you will know for sure once it is mounted to an engine and a test while the engine is running will reveal how much voltage the stator is capable of making.
