Charging voltage

[badkarma68]

I have owned my truck (2018 Ram 3500 mega cab 6.7) for about a month. The battery light and low voltage warning has been on about 15 times so far. It is very random when this happens. It comes on for a few minuets then goes out. It can happen when its first started, while going 70 down the road for hours, just about anytime. It has never charged above 13 volts. I have the 2 alt. Setup if that m ales a difference. Can anybody tell me what their trucks charge at?

Thanks

The normal range for just about any vehicle is usually 13.8 - 14.4 while idling. Use a good volt meter at the battery.

Hi badkarma68,

I understand why this would be concerning. If you decide to have this looked at by the dealer, let us know. We'd be glad to help with that process.

You or Have someone add a 1/0 ground between motor where batteries ground and truck frame with soldered & heat shrink connections with a anti corrosive paste. Its Likely the dealer wont do it. Not in the warranty protocol for this issue If the grounds check good sitting still running.
