i noticed my volt gauge was low-so i popped my hood and noticed that the battery on the passenger side was venting out battery acid and making a hissing sound. what gives?? looks like the battery is going to explode! is this a sign of overcharging? bad regulator? bad alternator? am i able to start the truck, then disconnect the battery, so i can get it to the dealership?

 

Sounds like battery has a internal short.YES IT CAN EXPLODE! Its covered 3/36,Don't make ANY sparks near it.

 

Please fill out your signature so we know what year and options you have.

If it were me, I'd take that bad battery out and drive it to the dealer in some other vehicle. Then put the new battery in the truck and then drive the truck to the dealer or Autozone to see if the charging system is doing OK.

If you don't have another vehicle, then the next thing I'd try is disconnecting that battery altogether, cover the battery cables with rags or tape so they don't short, and then run on just the one battery. The batteries are wired in parallel so it's possible to run on just one.

 

Bet charge system is fine.Battery is shorted internally.

 

had charging system checked. alternator is bad!! dropped it off at the dealer
this morning

 

Alt.will not check correctly with a bad/shorted battery.Needs two GOOD batterys then recheck charge system.Lots of Alts.replaced without need because of this.

 

gotcha!. thanks!
