    I have some bad news for you. First, there are a couple of fusible links down at the starter itself. I would check those. But, that isn't the bad news. Don't just check the fusible links, check the endpoints of the wire (or as close to them as you can get) with a meter as well. Not too long ago I had a similar problem. My fusible link going to the two post deal on the firewall was good, but I still wasn't getting power. However, the terminals were showing power. Turned out that the wire had broken inside the insulation. When I found a wire that had a good fusible link that showed hot on one end and dead on the other, I knew I had found my culprit. Tugged on the wire some and the insulation finally snapped revealing the break in the wire. Spliced it up and I was good to go again.

    So, I would follow the power wires from the starter to the fuse block and other various locations. Use a meter and keep checking until you find one that is not conducting. Then check for a fusible link along the wire. Finally, check it for breaks, burn throughs, cuts, etc.

    I know this doesn't help too much, but at least it may get you started.

    tx85gmcguy nailed it... happens to the best of us. Good luck with your repairs... its a pain in the @$$ to hunt down the exact place where the wires fail. Not to mention, now its cold, and the wires aren't going to cooperate very easily. [​IMG] Good luck!!!

    Glad to see you found it. I know I just about panicked when I lost power to 2/3rds of my fuse panel, but all my fusible links were good. Didn't really know where to start. Once I got started with the meter and found the bad wire, I was quite relieved.
