My check gauges light came on while driving tonight and my volt gauge was on the low end on the "safe" zone. I just replaced the one battery(drivers side) because it was boiling and very hot. and the volt meter would fluctuate alot. What do you think is causing this? PCM going bad, bad grounds? Thanks ahead of time.

 

Anybody got any ideas?

 

On my '98 12v, when the check auges lite started coming on, it was time to replace the batteries. That ended the lite problem.

both batteries load tested good. Any other ideas. if i have to ill replace the other one also. I dont know why the one boiled and now i am having a low charge symptom

 

did they load test them when they were unhooked or were they still tied together?

 

I did it with them unhooked. and out of the truck.

 

Chec the alternator, same thing happend to me and the voltage regulator failed. Just an overcharging alternator or a shorted battery causes the battery to boil and get hot.
