Factory ammeter

Reason for the "MAD Bypass", though that disables the dash ammeter. Some owners instead install a dash voltmeter. I added a shunt diode to my 3 1960's Mopars so that increasing currents begin flowing direct from alternator to BAT+. The ammeter is still active, but doesn't peg. My cars have the 1965 bulkhead connector with buss-bar feed-thrus for the higher ALT and BAT currents (retrofit to my 1964). Posted the details years ago.

Thanks for this info! That sounds like a very clever solution, but I want to make sure that I understand it correctly. Did you put a high current diode in a wire path directly from your alternator to your battery, so the current would bypass the dash when the alternator voltage got to a certain level higher than the battery voltage? And, did you remove the 2 bulkhead connector terminals and replace them with solid metal feed--thrus?
