Hey all
Recently I've made several posts about the electrical problems I've been chasing down in my truck and I have another lead as to what might be the problem...
Very long story short my 1991 F250 7.3 idi ats turbo diesel with e4od tranny is in limp mode and I've been trying for about a month now to get it back up and running. I've tried checking fuses and sensors and a whole lot of other stuff and I've discovered that I have continuity between the load side of fuse 18 and and my chassis. I don't think that is normal? I compared it to another Ford truck of the same generation and it didnt show continuity, leading me to believe there is a direct short to the chassis.
At the same time, I recently was provided an electrical wiring diagram for the instrument cluster in my truck (fuse 18) and it shows that a 'dual brake warning diode assembly' is on that circuit. I have no idea what that is, but I am quite curious about it because my truck began to have this problem immediately after a failure and replacement of my front brakes. Can anyone tell me what the dual brake warning diode assembly does and if the brake failure could have killed it, causing some sort of electrical meltdown or short circuit?
