Hi Blodger ,
thanks for that ‘info’ I was half suspecting I’d hear something like that, as you can probably guess I’m not over confident on the electrics side of things, and to be quite honest with you, I asked at my local boat yard and was given those two options, it makes one doubtful of who you should trust.
I know your advise is right, and I should sort it out before spending any money, I only wish the yard could have given me the same advise as now my confidence in them has gone down somewhat! (are they just after my money) Guess I’ll have to buy a voltmeter like you suggest but I’ve not got a clue where to stick the wires to test anything and I’m concerned about causing any damage to the electrics.
Thanks again jonny.
