    Grounding questions

    Sarge or who ever else has done a Battery relocate.

    First off, if you have not done this or are going to, follows sarges instructions. Works out GREAT!

    ok, now, i couldnt do it exactly like sarge did because my turbo is over their and i didnt want all that shit next to that enormous heater called a turbo, so i split the factory shit up and moved it all to the passenger side.

    My question, whats the best method to adding another ground strap from the block to the frame.

    the first one, i simply ground off the paint that covered the holes for the battery hold down tray and grounded their. all my grounds from the passenger side are their.

    Is the alternator internally grounded? or did i loose a wire somewhere??

    i bought some self tapping screws and was wondering if that would be sufficient for a second ground strap. Obviously, ill grind the area clean down to bare metal the attach the ground via the self tapper, i believe that will be fine since it will be bare metal on bare metal, just wanted the advice from the pros. i believe i have all my wires re hooked up. i left the ground off the battery so i dont fry anything.

    here is a quick pick of my new terminal that i did. You can that there is three wires, one of which is the alternator, the positive from the battery and the alternator wire. Every connector was put on the wire with solder. and they are solid This is just mock up, i will be undoing everything to paint the box, and loom the wires and move them all behind the brace, dont need anything interfering with the steering linkage.

    is a self tapping screw good enough for a ground strap to the frame?

    Couple of things. First...I would enclose your positive post there. I just used a cheap ass electrical box from home depot and spray painted it red Or get a rubber gromet (cap) or something.....looks good though man.....The alternator is grounded to the block.

    You want to ground the block to the frame. Then ground the battery in your trunk to the frame. Just come off the block....a bolt on the alternator.....something..... and ground it to the frame.

    sarge, i have a stupid question, i have a -10 bung on the driver side of the oil pan, well above oil level and im not using it now.

    can you think of any good use for it? may run a line off it up to the top somewhere with a breather for another place to vent crank case pressure? or is that terrible idea??

    Are you forced induction? Blower/turbo?

    If your blowing the dipstick out.....and you have vented the oil fill cap and the drivers side valve cover...then yes....but only if you have vented the other two area mentioned and still blowing the dipstick out.

    i actually havent even started the car yet with the new setup. Was just trying to think of a good way to utilize that bung since i spend the time and money on it, lol.

    i have plans to vent both covers yes.

    Well....I would be aware of venting moisture into my sump. You need to allow pressure an avenue to escape but you do not want to over do it and have a oil filled moisture trap.
