Okay, so I have an 87 Comanche. Every now and then when I push or release the clutch pedal, all of my electrical will cut out. Sometimes the motor will turn off, and sometimes power will come back fast enough to keep it running. I've replaced the battery, alternator, and refreshed all the grounds I can see in the engine bay. I've also checked up under the dash and can't see any wiring that's touching any part of the clutch pedal assembly. Anybody have any idea what could be going on?

 

Click on the link in my signature and do a complete ground refreshing as in post 1. Do the stuff outlined in posts 2 and 3 also. Don't skip any steps.

Is your firewall cracked where the clutch master mounts?

Anything in the engine bay near the clutch master moving/wiggling when you step on the clutch?

 

I was looking again and found fluid on the rubber boot on the clutch master. I think it might be leaking on to the fuse panel.

 

Should not cause complete power failure . It will however eat up fuse box and cause indivual circuit issues ....Been here done this ...

 

Have you check the main harness mounted on firewall that connects to back of fuse box yet ?

 

Not yet. Haven't had the chance to tear it apart. I still drive it everyday.
