    Ground wire

    Okay, seems like everytime i get 1 problem solved, i get another. So this time i have a drain on my battery. I came out to a dead battery the other day. Replaced it and the next day dead again (today). As im running through all my wires, i noticed this ground that connects to the firewall...the truck runs fine without it and seems to run better actually but is it necessary? ThanksClick image for larger version.

    Righty-o. That ground lead has no place attached to the rocker cover. Using alloy as a ground point will cause a weird electrolysis thing - all ground leads need to be anchored to a ferrous material like the block, chassis, exhaust system etc.

    most have a ground strap to the head on the last exhaust stud, and it goes to the little post on the firewall.

    I just checked the photos from my teardown, and mine is exactly where DroppedMitsu says, the aft-most exhaust stud.

    Looks like some dingus guessed where to put it back.

    (I've done that.)
