Hello,
I'm new to this forum and to Toyota as well... I have an alternator question for a 1999 Tercel, and I hope someone can help me... I just changed my alternator (for a good rebuilt directly form the dealer) because the battery was overcahrging (around 17 Volts) and the Battery Light was on the the dash. The battery light was still on, so I figured that the battery was finnished so I bought a new one at Costco.
Now the battery light still comes on intermittently, when I rev the engine it stops but it comes back on at idle. I discovered that in the
3 wire harness that plugs into the alt, the "S" wire is cut just before the connector but if I giggle it it sometimes is OK. Do you think that that's what's causing my Battery light top come on? What does the "S" stand for, I assume that "IG"= Ignition and "L" = Light. What does that "S" terminal do exactly???Thanks, Eric
