Hello all, new to the forum. My '83 na is failing the insulation test when tested at the harness. If i check the switch itself on the throttle body, it passes. The only advise the book has from here is to "check harness" (thanks book) I've peeled back a good bit of insulation to expose and follow the wire, looking for trouble, but can't seem to find anything obvious. Any advise or thoughts on this matter much appreciated.
