challenger 1800 caught air landed then dies

[joeydubz]

hi alll
today i went out with my girl on a 97 seadoo challenger 1800 and it has been running great, but today we went a lil crazy doing around 50 hitting a wake from anouther boat and we did catch a lillte bit more air than usual and just as we landed it died and would not even fart or pop but still turned over
so after rowing it back to shore to home(live on a lake) i checked all the fuses under the front right cockpit and all was well
but i pulled the rear engine fuse cover(charging/mpem)near the engines i noticed if looking at it strait the top left fuse was popped
i replaced it and hooked up my lanyard and got one beep and then it popped again
tried replacing twice and still same
turns but no start.............wtf happend
any help is much needed

I had this same incident happen to me, only it was in a car! HAHA
Since the fuse keeps blowing, it sounds like something in that system was possibly jarred loose and you now have an open circuit. Electrical problems are definitely the WORST and the most difficult to track down. I would start looking for a loose ground wire...maybe a component moved slightly and the wire is now shorting out against metal...something along those lines.
Good luck!

x2......start with the switch on shifter. If no, start where you have power (battery). Might have a broken pick-up #9

i thought i burnt my mpem but luckilly i found a thread that someone had the same problem....just unhooked both tachs and vroooom
thanks for the help and now i am gonna avoid hitting waves and catching air

Im confused what actually happened and how unhooking the tach fixed it. Did you just unplug it and the boat works fine? Did you hook it back up after it started again?

I'm confused also! Certainly that is not the fix in the Challenger troubleshooting guide!?!?

I had the same problem on my challenger last yr there is a electronic capacitor that brakes in the tach and causes the fuse to blow u can pull the tach apart and bring it to a radio repair place and ask them if they would solder the capacitor back .I did and my tach works good now.

:lol:
WOW! If that works, that is OUTSTANDING!
My F250 had the same issue with teh overhead computer...since its in the roof, the heat would eventually "melt" the solder that held 3 transistors onto the board! Took it out, soldered back into place, VIOLA! Computer works again!
