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?
