no power captain

OK, start by reading this article..................

You could have trouble with the fuse link, or with the bulkhead connector, with the ammeter itself or it's connections, or what is known as the "in harness splice." This is a splice in the black ammeter wire a few inches down into the dash harness. Only way to tell is to try and eliminate other stuff, then untape the harness from the ammeter black wire down into the harness until you find the splice

Pay particular attention to the diagram below, which is from the article I posted:

Functionally, power comes from the battery (red), to the starter relay, through the fuse link, through the bulkhead, and to the ammeter red terminal.

Through the ammeter, power goes down the black ammeter wire to the big welded splice, and branches off to feed several items, including the ignition switch, headlight switch, fuse panel "hot buss" and maybe a couple of other things

Not part of this problem, but as explanation, the black continues on, back out through the bulkhead, and connects to the alternator output terminal



WHAT I WAS getting at by using a test lamp is that if you happen to be mistaken about the ammeter being connected, or maybe getting to poke around in there, you can start a firestorm that is only protected by the fuse link, and that is damn poor.......protection that is

Since you had the panel out, my big suspect would be the ammeter and or it's connections. EVERYTHING goes through there

Your top suspects, somewhat in order are:

The fuse link, the bulkhead connector terminals, the ammeter terminals, the ammeter, and the welded splice.
