found good news,went got alternator checked ,it failed.just to be safe went too couple of places.3 places couldnt check alternator,couldnt get it too ground ?????? so im assuming this is big part of battery problem.local shop here been around long time,going too rebuild 150. ,and they will stand behind it.also found out batteries still under warranty.this truck normally sits alot,have everyday car too drive.but hope problem is know gonna b fixed.have new hpop too have put on.then thats it for this winter.next winter wiil be bigger injectors,stage one turbo.dont need race truck,400 hp would be plenty,800 torque,just for pulling camper.

glad you are making progress

Do you have intercooler? if not get a pyro gauge at a minimum before bigger injectors

Most that tow go wit T4 to keep things cool. Do some homework first before getting parts.

Thumbs up

Address that trans before adding a lot more power. I bet a low stall converter, big cooler, and a shift kit would take it far.

Good on local shops, I always prefer to use them when available. Invest in a battery tending device if you are able to do so, this will trickle them to keep fully charged. Keep us posted on the outcome of the rebuilt alt. I had to swap mine in a pinch as the rectifier decided to overheat!

You just had a long thread about truck not charging and finished with it was fixed. Why did you start a new thread with the same problems? I guess I just do not understand.
