Hi - my ski ended up on it's side (mpem) down and after i'd righted it the main fuse (15A had blown).

Tried several times in the garage to get it going with repeated fuse blowing. Popped all the mpem plugs and made sure there was no water in them. (there wasn't)

Then ski started fine on the hose and I thought it was fixed. too easy

A week later 300m of normal running down the river it popped the main fuse. Changed fuse on the water and the ski would start and then stop after two seconds.'

Back in the garage discovered the ski would start and only run if the start button was kept depressed. As soon as i let go of button it stopped.

Any suggestions ? I've pulled the mag cover and all looks good
