hi seadoo fans..... i am new.... very. plz bear with me.
1999 seadoo speedster had it out about 12 times. RAVE blade broke. late week... replaced.
i put the boat in the water, ran her at about 5000 RPM for about 30 mins.... ran great sounded great.
parked it for some fishing.... shut off boat. fished, swam... yada yada ...
tried to restart.... NO POWER
there is power to the horn and blower and lights ... i try to start boat.... no power to engines and the horn and all accessories/ electrical components die. i turn off hard power switch. turn back on... some times the components power return. sometimes not. everytime i try to start engines, everything dies. battery is brand new.

plz help me


i miss my boat
thanks in advance for any help

Sounds like the battery disconnect switch could be bad? If you can cycle that and it works sometimes I'd lean towards that. You should have power going to it from the battery and then coming from it to the 2 black boxes by the resonators. Simple to check with a volt meter. But given your description that very well could be the problem. Check with a meter before you go and buy one.

It's just a hunch but you kinda confirmed it in your post.

do you know the average price for this item?

 

[racerxxx]

Nope, here's the part number

It's a commercial part. If you pull it you can get the part number off that and search that.

well i pulled the black box out , the water proof one with the solenoid in it..... cleaned all connections. and she fired up very well, put in water and she died after about 20 mins... so while in water i took all connections out of that box and moved wires around a bit basically turned the lid upside down and then put it back in the box.... she fired up and i drove her to the dock .... while driving to dock all my gages died and the motors were still going strong lol its a nightmare but at least i wasnt stranded.... soooo i think i have a bad wire leading into that box..... any advice ?
