    I dropped in a new Optima battery...while installing and tightening the Positive cable, I allowed the ratchet to touch the frame and start-a-"sparking". Now, I have no headlights, no interior lights, the starter turns over fine, but no ignition. Oh yeah, ALL of the fuzes under the dash check good - not one of them is burned out.

    Any thought from the field??? /forums/images/graemlins/confused.gif

    You might have burnt the fusible link.
    I don't know exactly where it is, but you will only know if you test it.

    Watch for the muzzleflash!
    Check for the fusable link on the firewall between the heater and distributer.... /forums/images/graemlins/thumb.gif

    check the small wire from the positive side og the battery to the alternator and make sure its tight! That controls all your computer stuff. Also check your ground.

    Along with the fuseable links on the fire wall don't forget the ones on the starter as well.

    Yep, check the fusible links. Theres a "junction block" for the fusible link (power) leads on the firewall, towards the drivers side top, black piece of plastic, all red wires going to it. You can check voltage there.

    Just an FYI for the next time.... ALWAYS install the positive battery cable first. Then no part of the truck can complete a circuit to ground while you're tightening the clamp. /forums/images/graemlins/cool.gif You only have to avoid the negative post(s) on the battery.
