Fixed yet ? At least you've still got the sunshine. Rog Sunshine is gorgeous. Still moored in Stratford, original fix didnβt work. Itβs gone away again to be looked at, but chap wonβt be back with it until Monday. He is also bringing a used replacement, in case original is really broken beyond repair. Not a problem really, jumped batteries to starter so charging is fine. Solar also doing well. Son and gf with us, so we are partying before the lockdown gets us. At least this time we will be in the boat π Good luck with it - sounds like you have it in hand, Telemachus advice was Bob on π»π Iβm steadily pulling ours to bits ahead of its winter layup next weekend, onto blocks until mid Feb 2021 is the current plan π° Itβs not as horrendous as it sounds tbh, taking the seat/bed ply and dinette table to work to strip the old varnish off and treat them to a couple of coats of new yacht varnish. Water system all drained down, engine and gearbox oil changed, upholstery removed and cleaned, the old girl is looking a bit bare and spartan at the moment, Iβm trying to get ahead of the curve in case we have another bloody lockdown π‘

Best way, have a cold beer and let someone else do the work. Nemesis will come up with a snide remark about paying for convenience. Anytime soon..... It wasn't a snide remark - more an observation of a basic truth. The more convenient something is the more it costs - usually. Marx understood this but he phrased it slightly differently.

This is probably totally wrong but I would have simply measured the voltage at the suspect alternator with the engine running, carefully avoiding flying belts. If there was 14.4V (or so) the problem isn't the alternator. If not, the alternator is fooked, whip it off and get it fixed.
Is my reasoning flawed?

Not far off to be honest π worth expanding that youβd measure between the frame (casing of alternator) and B+ terminal and expect to see >13.8v (old ACR and A127 regs often hold the voltage that low) modern tackle should be in the area you mentioned π»π

It did occur to me if there was an external regulator maybe that is where the burning smell came from.
Or perhaps a burnt split charge relay.
Not sure if anyone uses those anymore probably more likely to be a diode based splitter if there is one. Not that it would be needed on a dual alternator arrangement.

If there was 14.4V (or so) the problem isn't the alternator. If not, the alternator is fooked, whip it off and get it fixed. Is my reasoning flawed? A little bit flawed in that external influences can affect an otherwise serviceable 9 diode alternator. I am thinking of a short to ground (-ve) on the wire coming from the warning light and connecting to D+ terminal on the alternator. The D+ terminal is internally connected to the 3 field diodes which generate the current for the rotor (controlled by the regulator). So if that terminal is shorted to ground via the warning light wire, that shorts the field diode output and thus no current available for the rotor, = no power generation. Id agree that a faulty alternator is the most likely cause, but there are other possibilities and when it is quite easy to check for these possibilities, it makes sense to do so before forking out for a new alternator which is not 100% guaranteed to be the problem.

Quite so, I just bought a new servo for my van and was busy cursing having to remove the m/c to fit it when I decided on some simple tests and found it was the one way valve in the vacuum hose jammed solid. Doh! Now I daren't send the servo back for a refund because as everyone knows if I do that the one fitted will actually break.

Whilst waiting to get it fixed, am I being naive to suggest a jump lead from the starter+ to the domestic battery+ will put some charge in whilst the engine is running? Just remember to disconnect it when moored. The original post did ask what to do.

Clarence is fully operational again. Bit of a saga but new alternator now fitted. Not impressed with Barrus. Anyway, all is good with us.

Are their after sales services any better? Barrus simply werenβt interested in helping. In the end a new alternator was sourced from a company up north. Very good, reasonable cost. Was the first time Iβd had dealings with Barrus. Hope not too need them again. Mechanic chap turned out to be a diamond.
