Thanks Steve,
I finally got to spend a little time on this thing today. I do not have a load tester so I just took it to Autozone. They said that the 12v battery is bad. Showed fully charged but not holding as many volts as it should? Car starts fine and I've driven it around some and it seems to function decent without the IMA assist. I did not have a chance to replace the negative and other 2 cables as you suggested. The battery is only a year old. So is the fact that the IMA/battery system is not functioning properly killing the 12V battery? I assume I should get the other issue resolved first before changing the 12V?
