1997 Challenger - NO beeps

[Jaxjag]

I just purchased a 1997 Challenger jetboat. It now has a new battery. The prior owner tried to jumpstart the old battery w/ a running vehicle. There are NO beeps when the lanyard is put on the post. (It was beeping before the jump.) The lights & blower motor operate. The fuses in the grey box next to the ski post are good.

The HIN is CECA2165C797 - single engine 787.

1. Is it probable that the MPEM was damaged?
2. Where is the MPEM located?
3. Is there a way to test it?
4. Where can I download or purchase/download a Service manual for this boat? I tried this site, but he does not have the 1997 Challenger manual. http://articles.richardhartman.net/jetboating

Thank you for your assistance. I am looking forward to getting out on the water.

We do have that manual....

We do have that manual in our library, all you need to do is sign up for premium membership!. Your mpem is in the back engine compartment on the starboard side, there you will find the fuse block. If your lucky, the 5 amp fuse popped before any damage occured.
Up front, lift the latch over the steering wheel and pull out the storage compartment, where the fire extinguisher is, and you'll see another fuse block for your forward electricals.
Let me know if you have any problems!
I have the 97 Challenger.....great boat!
Never jump a pwc/boat with a running engine!

To add to seadoosnipe...never charge the battery connected to the boat or use a jump box as these things surge the electrical system and causes electrical problems that get real expensive.

Jump starting....!

When jump starting a PWC or boat with another vehicle, you're leaving the door open to possible electrical damage.
The charging system to most 12 volt DC systems is 14 vdc. So, when you hook up a dead system to the 14vdc, you could do permanent damage as soon as you do.
If you are in a jam and need to jump, always make sure the other engine is shut down, therefore only providing electrical current from the battery and not the electrical charging system. If it's a car or other 4 cycle engine with an alternator or generator, see if you can disconnect the negative lead to their battery or un-plug the snap plug on the back of the alternator. Alternators and generators store a small charge in their capacitors..........this can discharge to your battery when you hook up.
The advice is, don't jump a battery. But if I was stranded with my family and someone offered to jump me, this would be my procedure in protecting my electrical system.
