Well the oldman's truck battery light keeps on coming on every once in a while, he keeps on telling me to fix it, so well here i go


The truck has two brand new batteries swapped in not too long ago, but the battery light continues to come on every other time he drives it, it will only stay on for like a minute but it keeps on coming back and its annoying the crap out of him.

I tell him to take it to the dealer since its still under warranty, but whats going on, he thinks its the alternator.

 

Might be a loose connection for the light at the battery.

 

had the same problem on my 03 psd it was a chafed wire. just my .02

 

thanks, i will check for that tomorrow in the morning. The dealer did have to pull the motor out to replace the headgaskets, so it could have been damaged, i will check

 

I checked what i could see, and i could not see any chafed wires. i did not remove anything to check deeper into the engine bay.

idk

 

sounds like a bad connection

 

This looks like as good a place to ask this as any, My batteries in my 07 are not holding a charge, not even overnight, I have time, so whats the best battery to replace mine with? I have the dual battery setup.

 

I personally run optimuns

 

check ground wires at front lower of engine for loose connections . i run interstate batts.

 

could be a worn out belt and or a bad pulley or tensioner.
