I couldn't find a definitive answer and what I have found contradicts other things I've found both here and in the service manual.
Can anyone definitively tell me what the grounding scheme should be on a '69 coupe? I've heard that the negative battery terminal should have a jumper to the fender, but the service manual doesn't seem to show that and most parts sources don't specify a cable with that feature.
Also, where are the ground straps supposed to be? I've had a host of issues that I think are likely due to bad grounds and would like to get them sorted out.
Well let's see. There is one small braided ground from the back of the pass side head to the firewall. Another just like it spanning the front subframe/firewall near the oil filter location. there are lots of grounding wires all over the car for various systems like the headlights, parking lamps, tai lights. Lots of them under the dash. There are even thin metal pieces that ground several nits together like behind the instrument cluster. Several on the body. Some ground through the body of the device itself to the engine block. I don't know where you would find a complete list of every ground for every part but if there were one it would be a long list.
