I just picked up a 1992 D350 dually
I have a FSM on order, and I have tried to make out the electrical diagrams on the top of the forum, but I just cannot make out colors and descriptions off those diagrams.
Anyway, I have these issues:
no brake lights
no clearance lights at all
no e flashers
No horn
Turn signals do work (all 4)
headlights do work (high/low beams work)
brake light switch does work
wipers work
dash lights do work (at least the ones with good bulbs)
I have 12v at fuse 4
no blown fuses
no obvious open fusible links
the overall condition of all my harnesses is good and unmodified
I'm expecting a manual next week, but I really would like to know if anyone can point me in the right direction before that. I am about to install a new multifunction switch, but would like to know if anyone can give me a few test points to verify it is bad before I swap it out. Also, is Mopar OE the only way to go, or is aftermarket suitable?
Thanks in advance
