    Hey, I was on the trail last night. and just after I locked my hubs I got in and my truck died, (ran smooth, then nothing)
    Got out and many of my mechanically inclined friends determined that the ignition coil on top of the distributor failed.
    After replacing this And putting it back together we didn't get it to start but we took off the coil cover and the electrical current was arching all around the wires within the housing ( when trying to start it) and I went back and got another One and still had the same effects?
    Please help my friend and Ihave no Idea right now what it could be.......Any Ideas would be greatly appreciated.

    replace the cap and wires... give the inside of the cap a light spray of WD40 to get rid of any moisture...

    did you drench the engine?

    There is supose to be a metal peice that also gets screwed down with one of the screws that holds down the coil and it goes up to where the wires connect. It's the ground strap....is that in there? Did you put the rubber pad and Dielectric grease down where the contact spring goes?

    Hey if you anyone that ha a VAT 45 battery tester or you could just go to a shop, but it could be that your battery is overpowering the coil. Too much energy from alternator, check your battery voltage, making sure it is no higher than 13.1 or so.
    Just my 2 cents.

    Do you have spark at the plugs?

    Sounds like typical HEI ignition module gone bad. Check for spark and if you still do not have it you have a bad module or
    pick-up in the dist. Let us know what you find.

    It definately sounds llike somethings loading up BIG TIME. Kind of all dressed up with nowhere to go. Other than tearing apart the distributor and replacing the module and pick up it sounds like another distributor is in order. I picked one up at Autozone a few years ago and it's been returned twice with no q's or hassles. Good luck, let us know what it is/was!

    Just a thought check the insulation on the wires going into the cap. My last dist. had no insulation what so ever.

    Are you getting spark at the plugs? Maybe I'm not understanding this correctly, but put the cap back on and see if it is.

    Maybe you have already? If you are getting spark, I'd be thinking fuel pump for an "all of a sudden" no start condition.

    just some more ideas.

    Why insist on counting when the ring gear has the tooth counts stamped in?

    I'm not sure what kind of insulation that I would need to do to the distributor...and to others it seems that the power is coming in the red wire and just arching over towards the back
    part of the housing

    You don't need to insulate the distributor, just check to see that the 3 or 5 wires on your distributor are still insulated. Maybe one of them is grounding out on the case?

    ???Where does current go to that is looking for ground, it appears to me that if you screw down the coils black ground wire that current still stays in the top part of the cap, unless there is a wiring within the cap that goes to ground, I'm just not seeing it???
    And JJ there is about 1/4 inch of wiring exposed on both the red and yellow coil wire

    I'm not sure but I think that black ground wire is more of a bleed wire. Theres alot of voltage going thru that coil, up to 25,000 volts. The other aluminum strap is more of a ground/neutral.
    I was telling a buddy about this he was thinking maybe a broken shaft in the distributor. All that juice is being loaded up and it's not moving whjere it needs to go?

    A broken distributor shaft or maybe the camgear fell off. In other words the rotor isn't spinning and distributing the charge to each plug wire. Remove the cap and see if the rotor is spinning when you crank the motor.
