Amp gauge vs volts gauge?

No electric wipers or heater.

All other gauges are mechanical except the fuel gauge and that is a new 12v sending unit. (Not sure how well that will play with the 6v fuel gauge?)

Looks like the new Alt is 90 Amp.

I believe this was a "6V positive ground" system but I'm not 100 percent on that. I'll have to refer back to the book.


I totally forgot about using a resistor. I have not worked on a old ignition system like this in a long time. Should I just buy a 71 dart Coil and resistor?

Thank you very much for your time and advice!
