I changed the Battery in my 2003 two years ago to a Optima Red Top just for this problem, I didn't want to come out some day and have battery acid eating away at the PCM. The Optima is a gel battery so there's no chance of acid leaking down. It's a crazy place to put such sensitive electrical components. :W

killian.
looking to do the same thing on my 04 Z06 this spring. Still has original delco right now. What is the catalog # you bought and is it the same dimentionally as your original. I have red tops in my 67 and 68 and love them. But i keep tenders on them always.

GM has had this problem before, a buddy of mine had his battery blow up in his 82' and guess what was right next to the battery in the battery box (and it ain't the washer fluid bottle). They could of at least made a separator or put it in the other compartment with the jack in the C3's then and remembered the lessons learned for the C5. I guess I need two Optimas myself.

I had the same issue with my '98 about 6 months after I bought it. The battery had already been replaced but the mess hadn't been cleaned up. My first sign of trouble was when the PCM started throwing codes and reduction of engine power. Kevin was swamped at the time and couldn't get to it right away so he suggested I take it to the local Chevy dealer and at least let them diagnose the problem.

When I called him back to tell him the stealership was insisting I needed $3400 worth of repairs... well, his exact words aren't suitable for print. :L

I took it back to him: he cleaned everything with a 50/50 baking soda solution, coated everything he could with plastic, fabbed up a battery tray and (I think) replaced my tac module. Along with a few other things the bill was under $500.
