    trouble shooting 98slxh

    Today, into the water. Starts and runs but won't go over 2000 rpm . MFD red oil warning light on but I changed to premix and put a om reducer in the Blue wire . Need to find the thread on doing the premix but can't find it in search.

    Change out the carbs to another rack but still ran the same. Installed new battery which is fully charged, Installed new CDI which is brand new from Watcom.
    Is the ski in limp mode do to the oil light being on? Engine shakes on bogs with any throttle at all. Compresion is 140 plus or minus 2 on all three.

    I have to imagine it defintely has something to do with the oil level.

    I am pretty sure a 33 ohm resistor is what is required to fool the system into thinking the oil tank is full. Did you make any other changes?

    MFD should read FULL oil if the 33 ohm resister was installed correctly.

    Instead of going to the oil sender, the 33 ohm resistor must connect between the blue MFD wire and the black wire (simulating an oil sender at full position = 35 ohms).

    You can check the resistance from inside the electrical box, and at the MFD connector to the wire harness. A multi-meter should show 33 ohms (plus or minus a few) between the Blue and Black wires. Pin 2 is Black (Ground) at the MFD 8 pin connector, and Pin 6 is Blue (Oil sender).

    The Blue wire going to the actual oil level sender in the tank should be disconnected.

    Be sure your 33 ohm resistor is solidly connected to the Blue and Black pins inside the electrical box, and protected from shorting.

    Thanks for stateing the instructiions so clearly. I'll be back on the water in no time
