Answer 1

I finally figured out this problem and found that this problem also occurs in some newer Models (early 1990s). The problem is an open ground coming from the wiring connector found under the stearing column. The way to troubleshoot this problem is to: Physically look at the wires on the side of the connector that comes from the stearing column side, any that look discolored or rippled check for connection on both sides of the connector. If that shows good, then trace back the deformed wire to where the insulation starts to look malformed or discolored and stick one of the OhMmeter probes through the insulation and the other at the connector and check for continuity, continue to do this until you find no (or high resistance) continuity. Once you find the bad section of wire, cut it out and splice in a new peice of wire using the same gauge wire. (or as close as you have as long as it is not smaller gauge). On my 1988 it was a white wire midway on the connector.
