Disconnect the ammeter
ammeters were used on cars with generators with no need for a high output as the power needs were minimal. when high output alternators came about you do not use them and have a voltmeter instead. A overheating condition can happen as all the power(amps) pass through 1 little wire and ammeter and will burn down your car. Not a good idea to still use an ammeter. You also need a fuse link out of the alternator to protect the car wiring.
amps used in old car; heater fan-5 amps; lights-6 amps; ignition 4 amps; radio-1 amp; total 16 amps.
amps used in modern car; heater/ac-10 amps; rad fan -25 amps; lights -6 amps; ignition- 8 amps; ecu- 5 amps; abs ecu-5 amps; radio/stereo -10 amps; power windows-10 amps; power seat- 6 amps; fuel pump 6 amps; wipers 4 amps; total 95 amps.*so a 100 amp 1 wire alternator would be needed.
