Alternator Swap

Postby Sundar » November 26th, 2019, 10:50 am

I swapped a QG18 90A alternator into my RB20DET, cause the previous was undercharging. When i try to start the car the dash cuts off and the engine shuts off immediately after. what could be the issue here?

I got thru, the GPS needed to reset. Btw the qg alternator bolted in normal with the exception on the tensioner.

So the gps unit was causing the alternator to undercharge?

No the original unit was undercharging hence i had to replace it. Installed the QG one and then this problem started. I think its the harness to the GPS tracker that has a short or some loose connection that causing the ignition to flicker on and off passing through rough road, which my poly bushings not helping. tomorrow i'll investiquire.
