    No Beep, But Gauges work

    2000 Seadoo XP
    my beeper does not beep when key is inserted. gauges work, trim etc.

    I did checked all of the 6 or 7 fuses on the mpem
    is there another fuse I can check?

    This is driving my nuts


    I have already tried 3 different buzzers.

    voltage reads really low when I have the meter on the buzzer terminal when i stick the key in. apparently i'm getting too low or no voltage. I read several threads on here but none with the similar problem
    I also read the manual and helps nothing.

    First thing to check is the pins in the MPEM connector. Look at your wiring diagram to find the two pins for the buzzer. The female pins in the MPEM connector are extremely fragile. What often happens is someone is having a problem (like your previous owner...), and they try to diagnose wiring problems by sticking DMM probes, nails, whatever into the MPEM pins, and ruin the grip. Go down to your local machinist supply house and ask for a #54 drill bit. (.055, same size as the male pins on the MPEM...)

    Note that inserting a 1/16" drill bit (.0625) will ruin the grip of the pins....

    Find the two pins, and insert the drill bit into the buzzer pins to test for grip; should be a slight friction on the bit. (forget the "ooh" "aaah" nonsense....)
    I bet you will find that one or both of the pins have no grip. If so, you need to pop off the front part of the connector to get access to the pins, and using a fine pick under magnification, bend the three tangs on the pin inward. Then test again with the drill bit.

    While you have access to the pins, you can inject 12V into both wires to test the continuity to the buzzer.

    If neither of these hints work, it is possible that the MPEM is bad. I've seen a couple that do this. (I have a 97 GSX that works great, but has no buzzer output out of the MPEM....)

    i think its going to be the mpem is bad not giving a chirp chirp. i checked all the connections and looked fine, and plus the old owner wouldnt bother to even disconnect a wire. (i know how he is). like i said i get a small voltage, but not enough to power the buzzer. I guess i'm only going to have to be based on my pisser to make sure the engine does not overheat.

    If you can't fix the buzzer (or even if you can), get some thru hull fittings and mount the pisser(s) someplace on the hull where you can see it all the time.

    Here are some pics showing this on my XP-L. I had two incoming water lines from the pump, one for the engine and one for the pipe. I put them on seperate pissers.
