Fairline Sprint: I have an electrical fault problem...

[Chi Man]

Fairline Sprint: I have an electrical fault problem, all additional instruments are non-operative, all factory fitted are working (i.e. Volvo gauges working, revs, fuel etc) lights and fridge working, but the depth gauge, VHF radio, chart plotter, FM radio, anchor windlass etc are not. Checked the main fuses on the dash all ok, checked all the individual fuses for items all OK, battery cut offs not on, trip button by battery charger not tripped, looked at switch panel in side cabin all connections ok. Any ideas? Is there another fuse box I do not know about? Any help appreciated or has anyone got a wiring diagram they could let me have?
Thanks
David

manual won't help - you will simply have to follow the leads back to the batteries and establish how they have been wired.

they will have been 'used added' at some point, and there is absolutely no reason to assume they will have followed any standard approach at all.

however, if they have all gone, it suggests that there is either a single source, or earth, to the auxiliary 'circuit' to be found somewhere.

have you had the boat long? has this just happened?

was the boat once called White Eagle (have to ask that!)

Thanks Duncan, that's probably what I will have to do, had the boat since April and all been fine until now, boat is called Avon Sprint (not Fairline sprint -my typo), think it started life on the river Avon as I bought from a guy in weston super mare, not too advenurous a name, thought about changing it but have been told to change a boat's name is unlucky!!.
Cheers

Fairline Sprint is the model - sounds like it hasn't been named, or the previous owner de-named it (or the one before that!) which many do if they are going to re-use the name on their next boat.

good luck.

Call it whatever you want ...every single boat I have bought had its name changed.

Get yourself a multimeter and start testing where the power is/is not. What initially looks like a good connection, can very well turn out to be a bad one.. I say this, as a faulty fuel pump on my car, had me buy a new pump, have half the dash out looking for relays etc to find the problem was infact the spade connector at the pump end 1mm from the end of the spade.

I have found a multimeter has been one the best buys I have ever made.
