electrical problem on 1967
Started my TI car the other day, it ran for about 5 minutes, then lost almost all the 12 volt juice, the car kwit, the horn did work, was not the battery or the 12 volt disconect. Put a charger on it and wiggled the harness behind the fuse box at the same time and things went back to working. What are your thoughts.

Keith - I'd take a look at the Fuse Panel connector focusing on plastic pieces the pins are in to see if the plastic has melted around any of the pins causing them to be loose and therefore making poor contact. This problem can occur if water has run down on the Fuse Panel causing an increase in resistance that causes heat and then the plastic around the connector melts. I had this problem with my 66 Chevelle because the windshield seal leaked. Good luck. Pete -
Re: electrical problem on 1967
The red 12 ga wire that goes from the engine compartment into the fuseblock area is badly stressed during normal use, to say nothing about 40+ years of age. That is normally where the cause of the problem you described is found. Search the archives for more...Bill Clupper #618Comment

Re: electrical problem on 1967
Keith: As the others have mentioned, this is a common problem due to the heat generated by the red wire running through the firewall connector behind the fuse box. Take off your fuse box and take a look. You'll see the plastic around the little connector pins has melted to the point that you no longer have a nice positive connection. The fix is to "hard wire" the connection with a short piece of 12 gauge wire that you splice into the red wire and eliminate the pin connection altogether. Tape it back up neatly in the engine bay and no one will ever know the difference. I'm no electrical guy, but I did this on my 66 several years ago and haven't had a single problem since then.
