I am the proud owner (or sucker) of a Red/shale 2000 STS with 140K on her. It has a couple of issues (rear windows being one) that I will get to eventually but the one I need to start with is the battery is not being charged. There is no B1911 code like I get on my 97 STS when the battery won't charge and the red battery symbol on the dash does not come on other than during the 2 or 3 seconds all the lights come on after starting the car. Alternator is new (1000 buck water cooled Delco one) replaced by the guy I got it from a short time ago (like 2 or 3 weeks ago) along with a new battery. Dash display says "BATTERY VOLTAGE 11.8V OK" like the car thinks everything is fine but the volts are really that low. He took it to a garage and they told him it was the "computer" that was bad, hence the reason he dumped it. I assume the output driver in the ECM for flashing the feild in the alternator is burned out and I don't mind replacing the ECM if thats what it is, but is there anything else I can check before I head down that route. Can I put a jumper from the positive terminal cable to the "F" (or "I") terminal wire on the alternator to see if it will charge without frying anything, that way at least I know the issue is between the alternator and the ECM. It may be the wire, or it may be the ECM itself, but I can check the wire with an ohm meter when I start fooling with it. Got to get rid of at least one of my 97's before I worry about this one. At least I don't have to do HGs on this one (yet).
