I have tested the resistancce and it checks out OK at 23 ohms
I have replaced the sprague, rollers, and springs with a Niche setup
I have tried a new armature plate
-The old one is straight but had grooves
-The old one sticks to the magnet much better than the new one does
-I can’t turn the old armature by hand when engergized
I cut the plug off the diff to eliminate the possibility of a bad plug – same results
Magnet ridges are even as I checked with a straight edge
When i run 12v directly to the diff from a battery it turns with more resistance but doesn’t engage the outer hubs.
Is there anything else i can test before ponying up for a new differential side plate and magnet?
Thank you so much!
