    96 XP electrical problem?

    I have a cousins 96 XP that is giving me fits! Last year I thought the small black wire was broke and we had a problem with grounding (typical 96 XP problem) I ran a jumper ground wire to the battery and it ran fine for a while. The connections are still good but the damn thing is doing it again. It runs fine out of the hole and then it just hits a wall and will not accelerate past about 4000.

    Choke does nothing for the condition
    new fuel lines
    new overhaul of carbs
    rectifier is clear not cloudy
    jumper wire from the coil to the negative battery cable in place

    I was leaning twords mpem. Anyone else have any ideas? Luckily I can swap out mpem's and black boxes pretty easy cause I own 3 of these damn things. Before I do that I wanted to take some advise.

    Things I can think might cause this:
    1 dirty internal carb filters
    2 water leaking into exhaust from manifold to head pipe gasket
    3 water spraying near the air box, I had found a leak one time spraying from those casting plugs right into the airbox, the only way I found it was running in the water with the seat off.
    4 bad rectifier, allows ac current through scrambling the computer
    5 restricted exahust, bad hose, waterbox or something crawled up in there
    6 coil breaking down
    7 once in a while bad spark plugs cause wierd things
    8 sometimes the simple trimming of the plug wires help

    that's all I got , hope it helps

    Typical bad rectifier. You cannot tell if it is good just by looking at it.

    I think so too. I replaced it already and it did not help. Going to try a spare MPEM tomorrow. Thanks for all your help!

    Double check the fuel lines at the fuel tank. There are markings to tell you where each should go. Make sure they are all in the correct spot. I had them installed incorrectly on a GTX once and it wouldn't get up to speed.

    Sorry if you stated it but do you have the grey tempo fuel lines?

    Fuel lines are up to date.

    It seems that this one had a piece of foreign matter on top of the main jet! It looks like a piece of hardened turpentine, almost string like. Not sure how it got there but, it turned out to be a partially blocked main jet. That is why when I would choke it to see if it would improve the situation it would only sometimes react.

    Thanks for all your input everyone.
