Guys,
I believe my bendix mag failed but wanted to ask for advice before shipping it down to tropic airpower for another rebuild.
I have 5 hours in the air and everything has been performing well, but today when I performed my Mag check prior to take off the mech mag failed. For info I have one non-impulse Bendix and with a light speed electronic.
I checked my P-lead and checks good in both key positions (off and selected). I noticed that the mag body was grounded so had someone spin the prop and noted it remained grounded throughout rotation after removing the ground wire and P-lead.
Next idea was points were not opening - so removed the mag back cover and rotated mag and confirmed points were opening. Checking conductivity across the two terminals it never dropped even with contacts/points open.
After messing around and with the help of a hangar mate A&P we figured out that the wire to the coil was constantly grounded. The question is "this isn't suppose to be grounded right? and this means I need to return the mag?"
To clarify this is the one wire that goes from the mag coil to the points connector.
Thanks
