08 rxp 255 quit on the water

[Rossp]

I have an 08 rxp 255 that quit on me out on the lake back in July. I’m just now getting around to trying to diagnose it. When I put the key on the post I’m getting voltage to everything in the fuse panel but nothing is happening. No gauges beeps or nothing. Does this sound like a ground issue or possibly a pcm issue. I’m not sure if the pcm commands the ground side of the circuits or not. Any ideas?

Sounds like the 30 amp relay in the fuse box.

I believe I swapped the relay out on the water from another ski and it didn’t work. I’m not 100% so I ordered a new one I will give that a try

Replaced the relay yesterday afternoon and it made no difference

I think your next steps would be to test the start stop switch and the dess post and be absolutely sure your battery is up to snuff both volts and amps.

Dess post is new and the battery is tested good. Could the start stop switch keep the gauges and fuel pump from running?

If the start/stop switch is stuck in the start/stop mode you won’t get power anywhere.

Got the issue fixed. Ended up being a bad ground connection. Cleaned all the grounds up and it fired right up.

That is awesome to hear! Which ground location do you think was loose or corroded?

I believe it was the battery ground to the block. I temporarily bypassed that ground by running everything directly to the battery and that’s what fixed my issue.
