Will post back with resolutions

Thanks again

Your voltage readings are in-line with mine. It's not until the battery is recharged that at idle the voltage on the ACC will read around 13 volts, mine varies between 12.7-13.3. I wouldn't worry too much about the specific values as there is also apparently a resister in the ACC to limit the voltage going to it to keep it @ a safe level. Correct me if I'm wrong but the alternator should be putting out around 14v...

I've had strange issues w/ my battery in the past, but, how is it starting firt thing in the morning or whenever you drive it? Does it seem weak to crank? If so I would replace the battery to be a good start.... Ever do a VMI @ the stealer to see what your car may have had done at a stealership in the past, could point you what to focus on????
