I have long since given up trying to diagnose automotive problems other than the most obvious. The Colonel, bless him, persists:
I’ve been hunting gremlins in the electrical system of the Magnificent Honda. A loose hot wire to the backup light switch was grounding on the transmission housing which I discovered after meticulously examining and cleaning the instrument cluster whose gauges had ceased to function. A clever diversionary tactic on the part of Satan.
About the only time I can find a ground is when I’m too close to a live wire.
Then again, Lucifer does not give up:
Whether I have fixed a speed sensor problem remains to be seen and the mysteries of cruise control await further investigation.
Still, “keeping a homespun Honda going for 27 years and 420,000 miles is no small accomplishment,” and the guy with the 16-year-old Nissan with 163k on the clock agreed.
