I was able to get a quick reply (email) from MAC Tech Support, and the diode across the master relay for our '81 J is a 1N2483. Alternate IN5060 or GE3720.

Interesting story from a Mooney pilot, somewhat related to this topic. http://www.aopa.org/pilot/never_again/2007/na0704.mp3

Great info! Thank you. I believe the part number and specs for the diode are in a MAC drawing that I do not have. (The wiring diagram for the airplane only shows that a diode is present, not its specifics) Tomorrow I'm going to call MAC Tech Support and attepmt to get a PN, or at least some of the specs.

So, with regards to the old style relay 6041H231 I have a question.... Our '81 J recently had an electrical issue where a ground short smoked the jumper cable between the two smaller terminals on the master battery relay. (Old style H231) The wiring diagram depicts a diode between these terminals, but I haven't had much luck locating a part number or spec for the diode...... Does anybody know if the newer style relay, H105, requires this same jumper w/diode, or could it have possibly been build into the newer design?? Or does anyone have any info on the diode I'm referring to on the master relay? Any help is greatly appreciated!

I simply pull out the seat bottoms, creating a void. Then the seat backs fold forward after pulling a release lever. As the seat backs are at a 45 degree angle, I pull them (the cushions) off of the back support, which then folds completely down to allow a flat cargo compartment behind the forward seats.
