"Reverse protection diode?"

Just measure positive to ground. If zero see if unit has any "reverse protection diode" or (unlikely) MOV, etc. Otherwise, you have a over load somewhere else in unit.

Diode is good if on the diode test of DVM, you get a infinite reading hooking up leads one way, and a reading with leads reversed. May want to "float" one end of diode to be sure. Wink
