    Question about 1998 SPX MPEM

    I have a 1998 SPX here. Ski won't power up and all signs pointing to MPEM being bad. Part number on MPEM shows it's the same as a 1996 XP and has a manufacture date of December 1995. Is this really compatible with the 1998 SPX? I checked the diagrams and it does not look like the part numbers cross-reference...

    That one is confusing. The old number won't match up with the SPX and there is no new number. Some of the ski's (SPX's for example) don't match up on the old numbers between different years, but the new numbers do.

    Junior, The MPEM is different on the 98 and 99 skis with the 787(800 motor) Any electrical grey box from 1996 thru 1999 will work on your ski. It could be from a 1996/97 gtx,1996 xp, 97/98/99 spx.

    Now that I think about it; I recall reading somewhere that the 98's wouldn't interchange with any other year.

    Nope, that is the wrong MPEM. The 1996 used a two box system, MPEM and CDI, whereas the 98 SPX is a single MPEM ski.

    278000510 (same as 96 XP). Manufacture date shows December 1995, which makes sense since it's meant for a 1996 model year XP.

    Nice! I'm still confused though why a 1998 SPX has an MPEM in it meant for a 1996 XP. I bought the ski from the original owner and supposedly it "only needed a new battery"
