check the battery in your multimeter.
If the battery in the meter is low you will get funny readings.

Time for patronising question! You do realise its 24V electrics so the batteries should read around 27V if fully charged? Sorry if that was obvious to you already. Pete7 has a copy of a P22 manual on his website. http://www.polar-ribs.co.uk/ I think it might have a basic wiring diagram in it?

Hi I have checked multimeter battery fine I expect 27v at the battery but the charge light has gone out and three of the trips have tripped out nav lights is one auxiliary charger circuit is another the boat starts fine when I bought the boat some one had had the dash out
and put it back with about six screws missing and the tacho was missing! I have got Peters manual but I cannot recall a wiring diagram.

You wouldn't happen to have two 24v batteries in series, would you? (27v x 2 = 54v - kinda close to 55v.)

If it's tripped everything could the regulator be broken?

It sounds like a regulator fault, you dont say if its 55v with the engine running and 27v with it not, but if it is then I would go for that.

You don't have the battery isolator switched to Off, do you? That would account for high readings on the charge circuit (and probably won't do your alternator any good.)

Do you get the 55V across the battery terminals with the motor running?
