hellododge friends.
I recently ran my older battery dead camping. We had a hard time getting it back to town after jumping it. It would die while idling, but I was able to restart it several times in our way to buy a new battery. We bought a new batter,installed it and drive about 200 miles, no issues. Yesterday we had been driving about an hour when the check gauges light came on, the battery gauge was not reading anything. We figured we would be needing a new alternator. We left the battery on to charge overnight and drove to auto store to have the alternator tested. On the way to the store the battery gauge was running normal. The battery and the alternator were both tested and are in good order. So I’m scratching my head. I have a long haul trip back home and don’t want to have any unexpected trouble on the road. Any ideas on what could be going on? Help would be much appreciated.

 

Cables, grounds and connections would be the places I'd be checking.

 

The alternator could be on it's way out and with all of the strain to recharge the 2 batteries could've cause a temporary overheating and shutdown.

 

Okay Incase anyone else ever has this happen! We checked all connections, everything was copacetic. We decided to go ahead and make the 1200 mile drive home. An hour and a half in the electrical gauge tanks again. We go to an autozone, they test the alternator and it’s bad! Should have had a second opinion! Thanks for the responses and help. Cheers. We made it safe home to missouri

 

Cool. Welcome home.
