Did charging dead RV batteries driving kill my Jeep Alternator?
Question first, then the scenarior.
Can charging 2 6V batteries while driving kill an alternator and battery?
I have two 6V batteries. I left them at the RV repair to check/charge (they were dead)...and they didn't get around to it. They told me I could charge them up while driving 8 hours from San Diego to Phoenix. I drive a 2007 Jeep 3.7L, 6cyl, 2 WD.
About 4 hours into the drive, the red battery light when on, on the dash. I didn't do anything about it (face palm).
I parked in Phoenix, then used the car for about another 60 miles, not pulling the trailer for the next two days. The battery light was on 1/2 the time.
The car ended up malfunctioning (eg wouldn't start or drive well and had lights flashing intermittently, and gave a U?141 code on the ODB), so I had the dealer check it out. They diagnosed need a new alternator and battery. The alternator is original (175K on the car), the battery is 1.5 years old.
So here is my question: can charging those 6V while driving kill an alternator and battery?
Thanks! Love the answers on this forum.
