Hi I have recently purchased a 98 gsx ltd I bought the ski as a none runner and was told it wanted a new mpem but little did the seller no that it only wanted a new earth lead from the battery and fired up , my problem is tho tat when I put the dess key in I get no bleeps and the info display doesn't come on.i have tested the buzzer and it works ok, can an mpem be partially damaged to cause me this problem and can I test the clocks myself to see if there ok any help would be great cheers

I had a similar issue with a 1997 GTX, one way to go is to replace the gauge but they run a few hundred even used (depending on the exact gauge). I went the replacement route only to find that the power wire going to the unit had gone bad. Pull the bottom of the hood off and look at the wires to make sure they are all in good working condition. I would then do a resistance test across the power wire and ground wire for the gauge, if there is no resistance then you have a bad wire in the loop.
If the wiring looks good and you are pretty sure the gauge is shot, I would disconnect the plug that goes to the display, pull the power and ground wires out of the connector and hook them to a spare 12v battery. Only do the 12v test if you believe the gauge is already shot because I have heard Seadoos can be tempermental with battery voltage. I think the voltage concern is only for jumping the ski but not 100% sure, so better safe then sorry.
If the gauge lights up then it is good and you problem is else where, if it doesn't then your gauge probably needs replaced. Good luck.

Cheers for that I have already stripped the front panel down and found bad wires and repaired them I bought another display of eBay but didn't work think I was sold a duff one but I'm going to do the test and see what happens
