Got a working Hirsch antenna from a reputable dealer that's bench tested.
My big question - why am I getting +12V with the ignition off at pin 5 & 6? I'm getting +12V at pin 1 which is to be expected. But pin 5 & 6 shouldn't be +12V until the switch activates them. I pulled the switch out at the dash and I'm still getting +12V at pin 5 & 6. No idea.
On a possibly related note, I just blew my glow plug relay fuse. Possibly unrelated though because I'm still finding some dodgy stuff from PO's. There was a 40 A fuse in there, but it's supposed to be 80 A.
Help appreciated! wiring from my w123 (pin 5&6 have the shorter wires) Antenna plug
