I have a 1990 dodge w250 (360 gas with 130k miles). It runs great mechanically, but about a month ago I lost power to almost all accessories on the highway. It died instantly. The only electronic components that still seemed to function were the vent blower, the headlights, and the windows. Not even the starter. My mechanic checked the ignition switch, and he said it's still good. He thinks it's a fried wire harness? Maybe he's right. I haven't had any luck.

Is there anything else I should check before I start parting it out?

 

Aren't there some fusible links down at the starter on those??

 

You nailed it! There was a blown fuse link on top of the driver side wheel well. Runs like a champ again!

 

I have a 93 Dodge Ram 150 LE 3.9L with electrical problems. No horn, dash lights, brake lights, radio, or hazard lights. Replaced turn signal assembly, delay relay, and flasher no luck. This truck runs great but it had been sitting for 8 years it was my step-fathers and mom couldn't let it go after he passed. I see no signs of rodents chewing on any of the wires and all of the fuses in the box are good. Any and all thoughts on this issue are appreciated.
