Ouse on Board?

I agree but as we are a charity and have young people on board we think its a sensible option.

I'm after one of those stickers that show the danger areas on the boat around the tiller and not to walk down the sides or on the roof. I can find one on Ebay which just shows the tiller area but its not quite what I want. Im sure they usually say British Marine on them but cant for the life of me find them anywhere.

Thanks all. In response to Ditchcrawler, there is nothing on the D+ terminal (see photo). I too thought it must need some form of excitation but perhaps being for the leisure batteries its in-built to the unit its self, self-excitation as it were? DMR - I dont normally run it with the isolator off, I was just doing some testing as I needed to be sure that it wasn't battery voltage. I did it with the isolator on as well and as there was no spike when the engine started I made the assumption it wasnt producing any voltage, either from not exciting or just being knackard. Sir Nibble- I dont have a part number of the one we have because a bit of research has deduced that its no longer supported and had been uprated to a 150A version - part number RDG201102021 which I have found stockests of. Lastly - the alternator was working fine, the last few times when I have started the boat I have had to "blip" the throttle to kick the alternator into life then its been fine, but the other day the warning light came on mid cruise making me think it is the alternator rather than wiring (although I'm still open to suggestions of other causes). I have attached a picture and as you can see there are only 2 connections. Sorry for the quality and angle, I took it to see the label rather than an over-all image of the alternator but as you can see, nothing on D+. The contact with the small wire on is for the warning light and I'm not sure what the last contact is for. There are no signs of and snapped or damaged cables which may have vibrated off etc. I believe its always been like this. At the end of the day its a boat, and like all the other toys in the garage, I shall probably just throw money at it until the problem goes away! Thanks everyone for your thoughts by the way.

thats with the isolator off (so batteries disconnected). with the batteries connected it was 13.2 but no change between starting and stopping the engine.

1.4. I think it was

Yes the warning light is on when the engine is running and there is no voltage coming from the alternator. Can you recommend a specialist?

Our domestic alternator has died and I am struggling to find a replacement. We have a Barrus Shire 40 engine with a 140A 12V alternator. I was going to just replace like for like but cant seem to find a supplier anywhere. The Barrus website is as good as useless. Are there any direct alternatives that would fit either new or overhauled? All help appreciated. Thanks (as a side note, I checked the voltage coming out of it today and it was nothing so likely it is the alternator or elements of it)

We offer training on board our own Narrowboat in Cambridgeshire or we can come to you (subject to suitability of boat etc). Narrowboats and Cruisers catered for. We are a charity so all fees go back into keeping our charity running making prices quite competitive. WWW.OUSEONBOARD.ORG.UK

Finally got ours finished and ready to go. Not a bad job but I'm pretty chuffed.

Thanks for all the ideas. Sometimes it helps to have a few ideas thrown around. MK1 made so will make a better version out of something tomorrow. Cheers all

Yeah this is my thinking if nothing else comes to light.

Todays job, trying to sort out the shower. Turns out the mixer just needed a good clean up, however it is missing the knob. I am struggling to find either a suitable knob or something to use as a knob. The main problem I'm having it that its a 7/8" drive which the knob would need to slot on to. All the ones i seem to be able to find online are small spline drives. Any suggestions? Its usable as it is - just, but with wet hands its quite a small knob to grab hold of at the moment There are no part numbers on the mixer unfortunately.

Best addition so far. Excuse the dodgy paint job, this has since been rectified.

Cheers all, I am going to climb down and inspect with torch and mirror, no problem doing that. I have a new relay on its way and a bulk load of 15 and 25 amp fuses so can do a little experimenting (one thing at a time though). You would think being an avionic engineer this would be a doddle but I think we are blessed with much easier to follow diagrams (with internal workings of components). I hate working with coloured wires all leading to boxes, however Flyboys diagrams are much better to follow so i may steal those

Yes that would make sense. It has to be something causing the fuse to blow while the engine is operating. Ive got a feeling the solenoid and starter are one assembly....£££
