Just got new 12v batteries however when I put the voltmeter across one, it shows 17V, is that OK?
Should be looking at about 14.4v with the engine running and about 12.8v without. A very good book on the subject is Boatowners Mechanical and Electrical Manual by Nigel Calder
Evening all, just popped over from the dark side, certainly a lot quicker than the other site, suspect I will be one of many fed up with YBW
