    Ok guys this one has my shaking head.

    Our 1995 Chevy 2500 pick up. Has a 350 in it.

    The problem is:

    The trucks charging at 14 and when you trun the head lights on it drops to 9, and once you pop it in to gear the truck dies.

    We swiched the Alt and put a new batt. in the truck..


    Any one have any clue ??

    Not that uncommon actually, it's usually do to a poor connection.

    Couple things to check...

    First, check all the grounds between the battery,engine and body for good clean connections making sure to also check the cables where they're crimped to the terminals.They love to corrode the cable strands up under the insulation.

    Next, check the wires at the starter that have the fusible links in the wires (not all trucks had fusible links at the starter but take a look).They have a bad habit of corroding inside the plastic fusible link cover and creating a lot of resistance in the feed circuits that supplies power inside the truck.
    Last, check all the connections and fusible links under the plastic panel on the pass side of the firewall at the buss connector bar.

    I would say check the grounds as well. Also you might have a short in the headlight system. Does everything work ok with the headlights off?

    Ok guys here is an update. There were a few wires that were in need of new ends, so we fixed them. The Main cause of the problem was the grund wire that goes from the block to the body was in bad shape, it breaks by just touching it.

    So we replaced the ground, and its as good as new.

    Thanks every one for your help.

    Nobody mentioned using DIELECTRIC GREASE to protect newly cleaned connections. Put it in junction blocks before you plug them in or back together, it keeps the water and dirt out. Make sure you get all the grounds cleaned and greased. Most of the lights and fuel pumps will have their grounds connected under the hood.
