current situation...electronic ignition,ballast resistor,fire wall regulator..stock 60 amp alternator...Dash voltage meter bypassed by aftermarket amp meter....everthing works fine.

installed chevy 1 wire alternator(100amp) and connected black heavy wire and nothing else.

amp gauge now reads slightly on negitive side of zero and battery reads 12 volts when running.(outside meter reads 12 volts as volt meter disabled,see 1st paragraph)

Do I need to disconnect the firewall regulator ?
What do I do with the two wires going to it ?

Thanks in advance...thanks moparts
