Hi i have a stupid problem, with my car off battery voltage is 12.4 volts and the when its running i have a voltage of 12.2 volts and it drops and keeps dropping and when the car is shut off and eventually when u shut the car off it wont start and will need a boost, but if u let it run for a short time if the voltage says 11.2 and then u shut it off the battery goes back to 12.2, and i followed all of the steps in trouble shooting the alternator. The alternator is brand new and has been tested by two different people and the battery is also good.
With the engine off, ignition off, I have battery voltage of 12.2 at the black/orange wires and battery voltage at the yellow/white wire. there is continuity in the white/black wire.
With engine off/ ignition on, the amp light glows. so i disconnected the harness and have 12.2volts at the connector with the green/red wire, reconnected the harness and probed the connector and have 3.7 volts.
Start the car and the voltage is 12.2 and drops.
please help me im banging head off the wall!!!!!!! Thanks,
