ok ive got a multimeter to see how many amps my car puts out when since I took out my module but, I'm not quite sure how to use it and what to look for. If anyone can help it'd be appreciated.

Ok i got the multimeter on there and its putting out less than one amp now that I have the module removed. Cant really tell the exact number since its not digital, I just know it didnt move past the first notch. Also, right after I removed the module the power to my door locks, and the door chime was restored. Would it be safe to say that the module is bad? I actually feel like I'm close to getting my problem resolved.

I didnt test it with the module in, I just kept in mind the 14 amps it was putting off when the shop had it. I was a little lost on how to hook the multimeter up and the older guy who lives next door came and put the contacts for the meter on each of the posts sticking out from the battery. I will test it again tomorrow with the module back in and see if I get a different reading than the one I got when it was out. If my neighbor and I had the multimeter hooked up wrong let me know so I can correct it and get a proper reading.

Ted, I did what you said and checked my ground busses again. They were both dry and free of corrosion. I checked the locks as soon as I finished and still got nothing. But like I said earlier they were restored along with the door chime when I removed the module. Hope this helps.

Here is a long-winded post and somewhat of a write-up on what I did to track down a parasitic drain. There is a lot of fluff in there, but hopefully I described some of the process and steps when using my multi-meter that may be helpful to you and others.

You need to disconnect the negative battery cable & connect the meter between the battery & cable. When I checked this on my 89 the meter would show over one amp & you'd hear the chime. After 5 - 10 seconds the PCM will go into a power saving mode & the meter would show .03 amps.
You can also pull a fuse and connect the meter to the fuse terminals. This will tell you how much current each circuit is drawing. There are also some fuses under the dash on the passenger side.

Yea I guess he did hook the meter up wrong. I will try it the right way today. I did notice that since I removed the module my battery hasn't died. It usually discharges overnight when I leave it hooked up but that didn't happen. Also I don't have a digital multimeter, it'* an analog one but I doubt that it matters.

Still haven't gotten a reading I can see off of the analog multimeter I have. The good thing is my car has started several times and my battery hasn't discharged since I removed the module. The next question is does anyone have an idea of where I can get one. I've called the junkyards around me and no one has any.

Most likely they don't know what they have.. Or what the part really is... There were a series Of Buick, Odls and Pontiacs that all used the same module from 92-95
