I noticed that I had a new warning light show up on my dash yesterday. I didn't know what it was then. The letter A with a circular arrow around it and an exclamation point. I didn't have time to address it then. Today, a Sunday, I was running errands and got home. Went inside and then came out to back it out of the garage to clean the wheels. After that, I tried to start it and got barely a click of the engine. Hooked a battery charger/cable up to the battery and it started immediately. Still got the warning light. Turned it off for a minute. Wouldn't start again. Hooked it back up and started off the charger just fine. I feel like the issue is either a computer glitch or some battery issue. I've read some posts about the secondary battery. Anyone have this same issue with car not starting and that warning light?

When I bought my Jeep the battery was dead. Dealer replaced it however that killed the 48v battery and I got the ESS not available warning. Dealer replaced the auxiliary battery and that fixed it.
