Car 1: 1990L Gold Sedan



iTrader: (0)
In he case of the alternater being bad, I am trying to find out if the ECU and TCU on 1990 L sedan is reactive to voltages less than 12.5... as I have just found & fixed mine after it would only do 12.8@3000 rpm and at city type driving it was only putting out about 12.2...battery still held up but i have heard that this condition can upset the system performance by staying in open loop till it passes 12.4Volts...and it can affect other parts of the electrical.... relays and senser readings...anyone know about this????????
