Drove my truck last Saturday night with no problems. Didn't drive the truck at all on Sunday or Monday. Went to crank it this morning and the battery was dead. I recently installed an AFM delete module on it, but I've let it sit for 3 or 4 days and had no issues, even with the AFM module plugged in the whole time.
Okay, so I unplugged the AFM module and put the truck on my battery charger, 2 Amp charge rate setting. Went out about 2 hours later, and the ammeter gauge was pulsing between 4 Amps and 6 Amps, and the battery wasn't accepting charging. I checked the connections to be sure they were good, even repositioning them, and the battery charger still pulsates. The battery is a Carquest Gold with a manufacturing date of 07/18.
Thoughts?
