I was curious if anyone knew which wires tell the pcm that the battery is charging or to turn off the battery light on the dash. I replaced the alternator with an after market that is not an OEM replacement. So i currently have the stock wires that ran to the alternator taped off. The blinking battery light is a little bothersome so i was curious if anyone has done something to get rid of the warnings in the dash. Ie, do i just need to ground the stock wires, thanks for any help.

FYI, trucks an 03 SSS.

 

L terminal turns the alt on, F terminal is the reference back to the PCM. If you have your codes scanned you will see a Generator F Terminal code, that it what is illuminating the battery light. I can't remember what the code number is exactly, but it will show in your DTC codes, then you can disable the code in your tune and the light will go away.

 

sweet, ill try that
