Tracking down an intermittent electrical problem. GPs energize intermittently when driving (at least indicated by instrument panel orange GP indicator lamp). First thing to look at for any electrical problem on these cars is the wiring-- Bosch soybean-based biodegradable insulation wiring.
Sure enough found bundles of the degraded insulation wiring at the 4-pin GP relay connector.
Managed to re-insulate, using a mixture of Liquid Tape, electrical tape, and heatshrink tubing. Problem persists so I need to investigate the wire runs further.
