The gremlins have been found and repaired. The gremlins were as follows:
- The biggest and potentially most dangerous gremlin was the 45-year-old umbilical cord. It looked good where it was visible, but once it passed through the banana wrap it had a section about 6" long that had been rubbing on a pass-through hole where the grommet had disintegrated. The following leads had been completely severed:
- Green -- Running Lights
- Brown -- Right Turn
- Blue -- Charge Line
- The following leads were chaffed but still working
- White -- Ground
- Orange -- Backup Lights
- The only lead that hadn't been damaged was the Yellow -- Trailer Brakes
- The second issue turned out to be the license plate light. The six-year-old license light and holder that I purchased from Airstream was so badly corroded that it wasn't grounding properly.
- The third issue was a clearance light that had been damaged in a hail storm which had resulted in water infiltration that led to corrossion causing a ground problem.
- Two fuses had blown in the Suburban, but it isn't clear whether this may have been related to some of the trouble shooting that we did.
All that remains now is to replace the two weakest clearance lights and a few burned out bulbs in the other marker lights and I will be ready to depart for the International Rally.

P.S.: Had it not been for my friends who helped with this project, I would have had to cancel my trip to the International Rally. They stuck with the project when I had to seek an air conditioned room when the heat index rose to 103 degrees on Monday -- and today it hit 105 degrees. I miss the dry heat of Western Kansas -- it was so much less objectionable than this wet heat.
