single wire Alt. & Amp. meter

I have a single Alt with an Amp. meter. I was not aware of a real problem as I have the car down for body repairs, however I took the gages out for another reason & found the Alt. wire to the Amp. meter had burnt the connector off the gauge. The wire is a number 10 gauge which should be sufficient as I under stand and the connection was tight in that a portion of the ring connector was still tightly under the nut on the post. In view of this condition I am now going to rewire the whole car, as this car was build in 1985 with about 50,000 mile and has a home built wiring system, however I am interested in knowing just what went south in this set up. I did do some rewiring under the dash a couple of years ago, when I replaced all the glass fuses with the bayonet style fuses, however I can't understand how this could cause this. I'm also getting the feeling I should be replacing the Amp. meter with a Volt meter.

I would appreciate any answers or recommendations (I have read all the survey results related to wiring harnesses & as with everything today, it seems impossible to reduce each to the lowest common denominator for evaluation)

Thank you

Doc here,

If you are now running a single Wire Alternator, you will have to go with a Voltmeter. There are no provisions for a standard AMP gauge, or light in the Single Wire circuit. In the stock harness.

Or you could go back to the 3 wire after your harness repairs are complete.

Thank you Doc

I'm told that it would be much safer to replace the Amp with the Volt which I guess you are saying would make any of the harnesses work?

Thanks Again
