So I been working on the power windows and found a bad fused link that feeds the heater/ac and powerwindows. I know it usually is a 20ga fusible link into the pink/black and they have been done already. Now the weird thing is a brown wire tied in with the pink/black wire. The manual does not show and brown wires connected to fused links and im curious if this is what has been blowing the circuit. Does anyone have first hand knowledge of this?
When I was replacing the fusible links on my 92 W250 last year there was a brown wire feeding off of the pink/black wire. Sorry, but I don't recall what brown wire was supplying, but per my shop manual it feeds the wide open throttle cut out relay.
Pics below include a shot of the wires in my truck prior to the fusible link replacement and a pic from my shop manual.
Looking at the wiring diagram, the pink/black feeds the ignition switch from the battery through the fusible link. Per the diagram, that brown wire is supposed to have come from the ignition switch, not before it. Either it was a factory service bulletin, or someone else rewired it to take the load off the ignition switch.
