    Seadoo spark irb problem

    Hi everyone.
    I was hoping to benefit from your community wisdom.
    I have a spark that has an ibr problem. When I start the ski I get an immediate alarm and the the ibr symbol is on. The ski start and runs fine. I have taken the unit out and test the motor for direct operation and it works fine. Before I buy a new ibr unit I was hoping to rule out the loom. There is a section where the loom has been repaired near the ibr connector.
    does anyone know the best way to test if the ibr unit has failed or the wiring is at fault? Could anyone help with a wiring diagram so I can see whatís what and test each wire.
    any help is much appreciated.
    Thanks
    Zac

    Also there was a little corrosion on the ibr plug pins. But it looked like there was still good contacts.

    By the sound of it, you should clean and re-do all the connectors and wiring.

    the ibr is unexpectedly sensitive to any unexpected/out of range sensor inputs reported by the motor controller and will throw a tantrum with just a small nudge

    it literally has to be space travel ready and all splices must be soldered

    having a code reader is very helpful in pinpointing the actual fault, but you can't go wrong sanitizing the wiring for starters

    thanks for that.
    All joins are soldered and look good.
    could you help me with a wiring diagram to trace and check continuity of each wire.

    service manuals can be purchased from a number of vendors on line. You can order the factory manual right here on GH ( use oem parts link above)

    if you spend a little time searching, I'm sure you can find the wiring diagrams for your ski posted somewhere, but since the wiring appears clean you have to face the prospect that the ibr controller is toast

    you might want to check the ibr mechanicals. remember I stated the system was sensitive?..what its sensitive to is unexpected current draw during initialization so a binding bushing can trip an alarm as the gate starts to check its travel range. The IBR uses a current feedback system to determine how much "brake" is needed after looking at the throttle position, the steering position and the brake lever position

    at the least, spray the pump down real well with silicon spray or xps lube.

    the IBR stays in N during engine idle, it only moves when throttle or brake are applied

    the IBR main logic board rivals any PC on the market

    sorry the news isn't any better, that's one pricey MF'r

    I though that sparks were throw aways when they expire on warranty.. Toss it out and buy another for a couple bucks.
