She didn't want an adventure she said.....just to go to Sams. I assured her things where different now. The old truck was being forged almost daily into a dependable driver.
OK
So we are driving along on a 2 lane road at night on our way to Sams when I decided to switch the high beams on. Instead of the high beams I got a complete blackout going 40 mph. This was not what I expected and certainly not what Kelly desired. As she firmly gripped anything close I jostled the headlight switch until I finally got the lights back on.
This "short" happened a few other times that night. Anybody have a good idea as to the probable source of the problem? My guess is the switch. | | | | | Joined: Jun 2000 Posts: 454 Shop Shark | | Shop Shark Joined: Jun 2000 Posts: 454 | Did it only happen when using the high beam switch? If so, I'd suspect the high beam switch. If, on the other hand it was happening when turning the headlights on or off, I'd suspect the light switch. High beam switches, because they are exposed to so much water, dirt, etc. are often the culprit. Also, before spending a lot of time on the switches, check the wiring and wire connections.

The headlight switch has circuit breaker in it that might have become weak, or maybe you've got upgraded headlights that overcome the circuit breaker.
You may want to use a relay for the headlights, or get a newer headlight switch that can handle more amps.
