I’ve had a long list of problems starting with a blown asd relay. After replacing it, I blew the wire that feeds the key on 12V supply on the ignition switch because the two connections it makes to that wire with the key on that is the blue wire and black/white wire, are both showing little to no resistance to ground. I traced them back to the fuse panel, fuse 17 and 12 are showing ground on load side with fuses out. I’ve traced the blue and white wire coming out of fuse 17 every where and I’ve disconnected it on several plugs. I’m lost now, any advice would be appreciated.

 

What do those two circuits feed?

 

17 in the fuse panel feeds Gauges. Warning Lights,
Speedometer, Overdrive lockout, and seat belt buzzer

12 in the panel feeds turn signals, van conversion relay, and antilock break module

 

Ok, the black/white wire feeds fuses 9-12 in the fuse block. The dark blue wire feeds fuses 17-18.

Pull all the fuses fed by one of the wires, see if you still have continuity to ground. If you don't, start putting fuses back in, one at a time, and retest. Test ALL of them, one at a time. I would not be at all surprised if some of the circuits don't show continuity to ground, depending on what a particular circuit does.

 

with no fuse, the 12 and 17 slots on the load side are grounding out

 

Actually, that isn't really a surprise.

Is fuse 12 the control side of relay, or the load side? If its the load side, that should not be going to ground...... Same for turn signals. ABS? Possibly. Unplug it, and test again.

 

Does the dark blue wire lead to a plug on the transmission casing, under the van? There is a sensor on the transmission which might be your overdrive lockout. That dark blue wire might be grounding out on your transmission casing. It happened to me and took me forever to find it. I taped it up with electrical tape and it stopped the short.

 

I found that, so you just taped up the sensor?
