Bad Volts!:09/20/2007
Several small lighting problems on the truck have been bothering me, but not enough to move them to the 'Do It Now' list. My 'Do It Now' never was short but the night before the right side lowbeam of the headlight burned out and that was the straw that sent me to sorting electrical problems.
There was that left headlight, I couldn't get it to adjust right. The left front parking light was out and the left turn indicator stayed lit whenever the lights were on, a sign of a short or a poor electrical ground.
So I pulled into the Walmart lot after work to pick up a headlight and bulbs and looked down and saw why the left headlight wouldn't adjust right. The previous owner installed the headlight upside down. Well, that's a easy fix, but I felt like smacking myself in the head for not catching it earlier.
Onto the turn signal problem. Swapping the left side bulb didn't work. I didn't expect it to, but who says you can't get lucky. At least the front parking light started working, after cleaning out a lot of dried white grease, one out of two. The wiring harness has several grounds. The bed lights ground to the drivers side frame rail just behind the leaf spring shackle. After cleaning, no fix. The cab section light harness grounds on the drivers side of radiator support, hidden by the horn, After cleaning and sanding the contacts it's fixed.
