I am having a problem with my interior dome light and headlights dimming, both when idling and driving. Batteries not fully charging also.
I have been to a mechanic and they checked the alternator and both batteries (had an extra battery installed under the hood due to having a truck camper that I live in in the bed of the truck. (See attachment) This mechanic was the one that said batteries were not fully charging.
The alternator is good, but the the batteries are not charging fully. Is the extra battery causing the problem? Do I need to install a stronger alternator or take out the extra battery?
have the same problem?
