You could check your TPS. I have a GM truck that did that when the TPS was toast. It made it force shift but also the the lock up in torgue converter didnt work either.

I put rock auto struts on my Bonneville with original springs. I might of got them in the LeSabre section , think it was these

Happy to say it is finally fixed, with the help of Harofreak.

I changed the PCM as that's where the draw was at. Then it wouldn't relearn the security, so this told me that next thing is to try changing the pass-key three security module. Went ahead and got that and the ICM along with ...

Thanks for the links

Harofreak is getting me a new pcm for a good price. If that don't work those vidios will help.

After waiting 8 hours car starts, battery didnt drop at all during this time. Shut off then after a few amp draw is back and jumping from .27-.69. I pull #8 pcm fuse again, put back in and it does just like before and drops off. so something on this circuit is not wanting to shut down. Thinking of ...

I was mistaken, that was the IGN. This car makes me crazy trying to figure this out. Yesterday the draw was at .34

Today it had huge draw .79 so started pulling fuses.
drop is amps going down
37 hvac batt .02 drop
29IGN .07 drop
25 has.02 drop
21 audio .45 drop
7drv mdl .02 drop
I then pull radio ...

This parasitic draw has gotten worse. So took meter to it again and found fuse 30 under seat to be drawing, it has IP next to it . trying to find what it goes to. I'm guessing instrument panel .

Started car with out that fuse and none of the gages worked. so looks like I need a new cluster or ...

New alternator and two wire harness installed. Battery load tested at interstate good. Battery goes dead in two days now. Gauge still reading dead in car but is charging.

The wire on alt. thats supposed to be 12 volt is reading none. Probably was before, that new meter is funky and not impressed ...

Called shop today to ask about second harness, tells me its the same that u need two. He is telling me one goes on alternator, not so i find out after searching that part number on line. I find that one goes to each cooling fan, jumper wire with a diode in it. Lucky the same seller had one more wire ...

Took it in and they said there was a tsb00-06-04-055 for this car which calls replace alt and install two jumper harness, one being part no.12165487. going to have to call back to find out the part number for second harness but found the one for $16.00 shipped (ebay), they wanted $200 for it only ...

In your diagram it shows coming from the dash integration module. Do you no where that is? Maybe part of cluster.

YA i thought it was strange, how it could get that high.

It wasn't plugged in, just touched 12 volt to alt. I do think something is wrong with the pcm though, and it might be my other couple issues

I'm getting 5 volts at B


getting 38 volts at D

thanks 95... I'll try that.

Earlier I used a test light to trigger the alt. on the L terminal and the alt starting charging.

I think the L terminal is B on your pic.

Is the PCM in or under the air box.

I think I've done something to the charging system (maybe ECM). Put known good alternator in and still no charge. Checked all fuses and are good. I'm at at loss. Car does run just no charge as of yesterday.

Got my gauge and still not seen amp draw after two hours just watching meter max never went over 1.8 mA. Was going to go for a ride and now alternator not working. Got one from junk and its not working thinking I might of done something. Will try to get alt going tomorrow. Then back to the draw.

I ...

Car drained battery after 4 days, so ordered a meter with memory & blue tooth.

Received the test switch today. Really no change in the readings I was getting before, .01. Went for ride came back, one thing I noticed when turning switch on and off I get a relay in the car that clicks, this is with the meter on, also the dash does some cycle thing when switch is closed.

So I ...

I have one of these at the shop I partner at with a friend on the weekends. It helps track down current draws like you are having and you don't have to worry about frying a fluke meter etc because you went past the 10amp max most meters have.

thanks ddadler.

What I did yesterday was put the amp meter inline and after it all shut down I never got more than .03 amps( is 30MA ?) watching up to 20 minutes. From what your saying is it must have hard wire hooked up then first then meter hooked up after that unhook hard wire. maybe this can ...

Was just reminded last year when hooking up battery the car alarm came on and didn't want to shot off till started car. It just did this when hooking up meter to read amps at battery but just one honk then the flashers came on for almost a minute.

Note battery is fully charged and held all night ...
