Thanks eq1. I started trying to fix another ima battery. I grid charged it for 3 cycles then I measured the voltage on each stick. They all came in between 8.45 and 8.54 volts. This seems fine to me...but what the hell do I know . Then I tested the ptc strips for voltage and they all had between 1.4 and 1.6.v Does that mean I have a short somewhere? I thought they were supposed to be 0.0.I skimmed through that thread, there should be enough to get the problem solved. Two problems mentioned were a blown fuse #24 (underdash) and a corroded connector/ground I think on the floor in the area behind the seats behind the rear speaker panel...
0.09V resting difference may be of concern unless they've been sitting a week, and that might be okay.Thanks eq1. I started trying to fix another ima battery.

Yes I think you are right Willie. I was doing the ptc strip test wrong. I went back and read the thread and Steve told me to put one probe on the ptc and the other on the stick to see if voltage was there. That is what I was supposed to do. That will tell me if there is a short in a strip. I will do that tomorrow. Thanks my friend.Looks like you hit the "olhms" key by mistake.

I would suspect:I went out to try to test the ptc strips again...the right way. I got 0 voltage on one then I tested a stick again to make sure I had voltage there. I didn't. I cant find voltage anywhere now. I don't know what that means but it sounds like a short drained my battery.
I also have a main seal leaking. I will go find a thread on that to see if I can replace it from the outside.
I added #4I would suspect:
1) operator error
2) instrument error/failure
3) short drained the battery
4) Something catastrophic happened to the battery, and it's shot.
Confirm the voltmeter works on another battery before further troubleshooting.
Ok, I will toss em. ThanksPersonally, I'd sh!t can all the sticks. Something bad has happened. I've seen sticks in a much better state be unsalvageable.
Everywhere you've seen corrosion likely means a leak. Anything at or near 0V has likely been shorted due to the leak and the PTC strip - dead.
I suspect that pack was grossly overcharged and some point, and it's ruined.
My advice is to abandon all hope and ditch all 20 sticks.
Not sure if it's been mentioned before, but since you're talking about shrinking sticks, that means you will have bare sticks at some point. If you ever get the idea to install all the bare sticks in a pack for testing - DON'T. It will catch fire. The rubber in the case is conductive.
Steve
EDIT: your results explain why it wouldn't go above 120V. All the more reason to avoid ALL sticks in that pack.
Thank you. I'm really glad to hear it. I'm one who has difficulty resisting the urge to tinker, and these stinkers don't deserve no tinker.Ok, I will toss em. Thanks
