Electrical Bulkhead Connector Question
I am getting 12 volts from the starter to the bulkhead connector but not getting power to the fusebox at all. When I backfed the fusebox from the battery, everthing worked till I drove it around the block and shut it down. Now nothing but the horn works! I have taken the bulhead connector apart and checked both sides. All looks ok. Should I just plan on a re-wire??? Does anyone have any words of wisdom?

Check your ground straps & cables. When you checked for 12vdc in the cockpit, you probably ran the (-) VOM wire to an "assumed" ground...and it showed no voltage. I doubt that the fuseblock is the problem; more likely a bad ground to the passenger compartment.

Thanks for the quick response!
I made sure I had a good ground for my (-) VOM wire. When I first ran a hot wire directly from the battery to the fuseblock (bat) pin, everything worked including turn signals etc. and I drove the car around the block. When I shut it down everything except the horn quit working. Oh yea, and the interior lights still work with the door open.
Hers a little more history. I bought the car from my uncle last year. He had it since 78 and blew the engine in 95 where it sat until I bought it. I rebuilt the engines, suspension, brakes, everything except the wiring! When I went to start it initially I had no power anywhere in the fuseblock. That is why I backfed it from the battery to see if it made a difference. It did, at least for one trip around the block.
I am thinking about a re-wire but I cannot tell how the Engine harness and the front light harness separate from the outer bulkhead connector. I called Lectric Limited (harness manufacturer) and they told me to pry the 2 harnesses apart from the BH connector with a screwdriver. I am not sure if I want to do that.

Thanks for the tip. I don't remember seeing any fusible links at the horn relay but, I will certainly check again. There were 2 links near the starter and I made sure both of them were good. I made sure I had 12 vdc going all the way into the bulkhead connector but have nothing coming out. I took apart the bh connector, looked at both side of it for burns or damage, and I took the fuse block off the inner bh connector and there was still no aparent damage. Any other thought? Thanks Again!

Thanks so much for the picture and info. I went out and looked and mine is just like the picture. I have not checked those links yet but I did check the one near the starter originally and it was fine. I was thinking there were 2 near the starter but I guess I had it backwards. I will check those 2 at the horn relay as soon as I get back out there.
