Ground locations

[rturbett]

Just waiting to hear the responses.. this has nothing to do with altimeters and dirt....

Is there a list of all the grounds and their locations on a 1980 m20 J?   I'd love to clean each location.   

I've gone through the service and parts manual, but can't find what I hoped would be there.

Thanks,

Rob

It will depend on the serial number. Grounds will be shown on the wiring diagrams in the service and maintenance manual Vol 2 (or in envelopes in the manual if you have an old paper copy).
