Had to replace the auxiliary battery again, battery is 8 months old.
O'Reilly warrantied it and the guy told me that the previous company they had making the batteries for them was having quality issues, the one I just put in should be more reliable... I hope.
That old battery only had an 80% charge even though I attempted to charge it with an agm charger.
The battery tester tested it as Good but with only 80% charge, it's the only thing I can think of that would make it give the error code.
put the replacement in, started the jeep, no error messages.
I wish I had my multimeter with me, I'd like to know where the aux battery wires end. I took what I thought were the two grounds from the body after removing the main battery and they were still sparking each time they touched the body.
Anyone know if the aux battery charges while driving or does it only feed off the main battery?
