AC compressor ground wiring

[Christian Doerk]

Hey guys,

hope you can help me one more.

I'm wondering how the correct wiring of the AC-compressor ground should be. If you do it like in the original shop manual on page 13-45 (Fig. 13-32, marked red), the compressor does not have any contact to the ground, because of of the rubber shock absorber of the compressor. So there must be an additional wiring from the compressor to somewhere with ground. Currently my wiring is attached to the bolt where you can adjust the tension of the belt, but this is not very practical.

How was it originally in 1964? Do you know?

Jason, thank you for the photo. I think this solution is the best.
But in the shop manual page 13-44, Note 37a. (Compressor Removal and Installation) #6 the text is: 'Disconnect clutch coil wires and remove screw securing ground wire to compressor'
So it should be correct on the compressor.

As I found out, with some more investigation, one car does have the ground on the compressor, another on the right thermostat housing, another again does have a longer wire, which connected to a bolt on the engine block etc.

@ Dan: rubber mounts on the rear of the compressor?! I don't have rubber mounts there. Is it possible to take a picture?

Compressor switch feeds the compressor via black wire (page 13-26 in 1964 shop manual). Black/White wire on same connector ground to right side thermostat housing bolt from factory.

  Here is a lo res picture.. I'll try to find a better pictures:
