    Red wire to negative terminal black wire to positive terminal. The red wire melted from the negative terminal to the alternator then from the alternator to the voltage gage

    I assume you disconnected everything. Remove the battery. It’s probably fried, but check it anyway. Any number of other things could also be ruined. Remove the alternator and have it tested also. You might luck out but don’t count on it. There should be a fusible link installed in this circuit and from your description was not. Remove and replace all suspect wiring and check all the remaining wiring for continuity just to be sure it’s ok. You can find wiring diagrams in the reference library on the left here. You’ve got a mess on your hands but you are lucky it didn’t go up in flames. 

    Good Luck.

    If you’re running an electronic distributor or a points replacement module, it is likely fried.

    Module will do it. That was the first thing that got killed. You could also go back to points and condensor, at least for testing. It is the old car person’s tradition, after swapping in the Pertronix, to keep the points kit in the car’s on-board spare parts bin–“just in case.” 

    Sometimes they do come in handy.

    There is one thing RJL is forgetting. Punctuation. LOL

    I’m thinking of a small trailer for my “car’s on-board spare parts bin”. Not a lot of room with a front engine for much else.

    I thought your parts bin was Dave’s Sharpie mobile.
