At this point I really don’t know what’s good or bad on battery voltage. The dealership that I purchased it from is pretty small. I just hope they know something about the JL. I’ve only seen one other JL on their lot, so? 14.7-14.8 all the time seems high to me. Seems like it would burn the battery up being that high all the time, but who knows. Just hope they figure something out. I actually miss driving it.I was just at the dealers and I discussed my high voltage with a tech. I told him it was running around 14.7. He said 14.7 is acceptable, but 14.8 is a problem. For now, I'll just keep monitoring until it goes up or something fails.
