Cox electrical in Atherstone is another. Repair will be considerably cheaper than replacement. Agreed. Midland are charging £350 for a 90A replacement. Balmar wanted £650. I was told Beta ones were £200 ish. Repair is the answer if bust...but what is broken if it produces 40A at 13.6V? Would one of the phases going give that effect?..or is it the internal regulator that has gone? ...or something else? Link to comment Share on other sites More sharing options...

Beta are quoting £278+VAT for the like replacement (14V 175A IA1196 ALTERNATOR 11.203.340541). Although I will be checking with them if its regulated to 14v or as some other people have mentioned in previous posts to 14.6v As I'm betting on this being the problem if in the end it doesn't turn out to be that I can just return it for a refund minus postage.

cuthound Posted April 22, 2018 Report Share Posted April 22, 2018 Have you measured the voltage on each alternator a d battery with a digital multimeter? The analogue panel voltmeters are notoriously inaccurate. Link to comment Share on other sites More sharing options...
nicknorman Posted April 22, 2018 Report Share Posted April 22, 2018 (edited) Right, there is a lot of misinformation on this thread. On our boat we have a Beta 43 with a 175 A Iskra alternator and a Mastershunt. Normally on starting we get 150A or more on the Mastershunt current indication. It drops to around 100-120A fairly quickly. Once the batteries approach fully charged (and the Mastershunt is pretty good if set up correctly) the current will of course fall right off and the voltage will reach 14.5 - 14.6v. So there are only two possibilities, one that the alternator is defective, the other that there is a high resistance connection between the alternator and the Mastershunt. The latter seems unlikely but easily checked by measuring the voltage actually on the alternator connections. If it is still 13.whatever at low currents, the alternator is faulty. One thing is certain, it is nothing to do with the batteries. It is nothing to do with split charge systems. It is nothing to do with the engine alternator nor engine alternator voltage showing on the engine instrument panel. Ok, three certain things.

DasDsm Posted April 22, 2018 Author Report Share Posted April 22, 2018 Thanks all, really helpful to confirm my suspicions. New alternator will be ordered tomorrow. Btw.. I don't know if there are usually always the same belts with a Beta 43 and 175amp alternator but having trouble finding a decent place to get a spare. Looking at the current one it's coded as 6PK1170 So any advice on stockists would be welcome. Thanks again all. I'll update once new one fitted.

Chewbacka Posted April 22, 2018 Report Share Posted April 22, 2018 If I remember correctly the 6pk means it’s a poly v belt and 1170 is the length in mm. So if you have a reasonable amount of adjustment then a few mm either way will probably fit ok. Google will give you a good selection as will many motor factors. A quick google shows Honda and Audi both use an 1173 belt. Link to comment Share on other sites More sharing options...

nicknorman Posted April 23, 2018 Report Share Posted April 23, 2018 (edited) I just ordered all 3 belts (we have a travelpower so a second polyvee belt), 2 oil filters, a fuel filter and a thermostat gasket all for £105 incl delivery, direct from Beta. Came quickly. Doesn’t seem too bad. Edit: just looked at the invoice, £19.95 for the belt and £5.90 for delivery + Vat.

The belts last 1500 hrs or more so as a boating expense, £25 or whatever is inconsequential whereas an early failure of a belt leaving one with no domestic power is a “big deal”. The Amazon belt seems unbranded, the Beta supplied ones are Hutchinson, made in EU. Link to comment Share on other sites More sharing options...
nicknorman Posted April 23, 2018 Report Share Posted April 23, 2018 If you want cheaper, I’d go for this on eBay, Gates is a top brand.: https://www.ebay.co.uk/itm/Gates-Drive-Belt-For-Audi-Citroen-Nissan-Peugeot-Renault-Toyota-Volvo-6PK1173/172786451711?hash=item283ae004ff:g:fk0AAOSw6dNZb3h9 By the way, my belt is an 1175 and there’s plenty of adjustment so I think an 1173 would be fine to replace an 1170 unless the adjustment is very near the limit.

Always keep a set of "used" belts on the boat that can replace a failed belt in minutes, just because a belt is new and from a decent make / supplier doesn't mean you are any less stuck if it snaps after 10 hours Link to comment Share on other sites More sharing options...
DasDsm Posted April 29, 2018 Author Report Share Posted April 29, 2018 Just to update: I've swapped over the alternator for a new one from Beta and charging much better now and voltage has gone from 13.6 to 14.4 while charging. The alternator was pretty covered in black carbon brush particles so looked like it was pretty worn. Now what to do with the old one? I'll probably look to get it refurbished and then see it on. Thanks all for the help. D Link to comment Share on other sites More sharing options...

If you are still looking for someone in the watford area to overhaul your alternator i will check out details of the person i've used a number of times over the years.
