    Kind of a urgent question, the truck was starting just fine with the Optima blue top charged, yesterday I drove a little to far and dye on me..the whole afternoon/night I spend charging the battery (with t h e optima 400 charger) to full and the freaking thing still those not start, y I u only hear a small ''relay'' click but nothing else..did a blow a fuse, is it a lever to turn/button to reset that I don't know about..??

    Today is my three year old birthday and I need to run around all over the city for hours on end and with out the truck I'm fubar..

    Okay I think something is Wonky here

    How can the truck run with out the 100A “main fuse”

    The other two look okay but the one on the left side is just missing

    The “missing” fuse is normal. Nothing goes there. Check continuity with your multimeter for the other fuses before replacing them.

    Might be a good idea to start new thread since the problem at hand might be more than just the alternator.

    Sorry I keep asking silly questions but in a hurry (is going to snow tomorrow)

    Here are the three wires from the stock alternator

    Here are the ones from the sequoia, as you can see none of them match

    Where do they go..??

    For '98... Not sure if wire colors for your year are the same. Basically match up the IG, S, L leads on the vehicle with the correct position on the 130/150A alternator. The "M" lead on the alternator is not used.

    Here's your pic... Look at the wiring diagram. The "M" is not used.

    How can you tell what size alternator you have? I called my parts guy at the dealer and he asked me whether it’s an 80 or 100 amp.

    Just want to mention
    IG: Ignition 12V comes in when the ignition is on
    S: Signal. A wire runs directly to battery (through a 7.5A fuse located right on the battery positive clamp: Should say signal)
    to monitor the battery current
    L: Light in the dash
