Funny to watch as an outsider. I bet the group and the leader all hated it. ^^^^
Welp, the 911 seat will now recline. The motor was fine, as I expected. It is of course a DC motor with a blue and a black wire. The black wire had a cut in it, and I can only guess is somehow it got under the seat rail and got pinched. That or the CIA broke in, using extraterrestrial technology and cut it just to be mean to me.
The outer plastic sleeve had no sign of a cut or damage, so it is a mystery. Anyway if I was smart I could have just opened up the covering sheath about a foot and found the problem and not had to mess with the expense and time of the upholsterer. But first I would have to be smart.
It is weird the plastic covering for the two wires had no marks or indication it was damaged.
The wire is fixed, and if I apply 12 volts the motor runs. So just two more 40 mile round trips and some money to get it back with leather. Then 4 difficult little Allen bolts to get back in and some connections and I will have a 911 fixed and it will recline!
The offending wire.
The naked seat back.
The motor is up inside the grey headrest part on the right. In the bottom photo about where is curves back away is the area where the wire was broken. It had some bends in the plastic after 35 years but no breaks.
