Wil

ok thanks

Faulty pump was 25psi and as the Morco boiler never performed that well I thought I'd give 40psi a go. Think that's wise?

I don't have a calorifier. Just taps, shower, and a morco boiler. Reckon 40psi is ok? I actually ordered the 40 psi one yesterday so would need to amend the order 1st thing in the morning if it's not!

Know anywhere I can buy one in London?

Thanks for the suggestions. Well a par max 4 be a straight swap out? Ie same connectors?

I took everything apart, cleaned the filter, blew through the pipes, and ran the pump by itself. There seemed to be no suction created by the pipe even though it was vibrating lots

What do you mean by Air Lock? Trapped air pocket?

My Par Max 2.9 stopped working today. It spluttered for a minute or two and now wont pump anything. The motor does however continue to chug away and the unit vibrates as much as it used to. There is just no suction created. I opened it up and couldnt see anything wrong, but neither could I see how the thing was meant to work! Does anyone have an idea of what might have gone wrong? Cheers Will

Does anyone know where I can buy a cheap morse control for a narrowboat? I need one of the dual function ones where one lever controls throttle & gear. All they all really £150+ ? Cheers W

Right yes, it did occur to me that I could use two matched leds, one as an emitter, the other as a photodiode. Didn't realise ldrs had slow response time. Interesting about the ac waveform! What is the w terminal for on an alternator?

Thanks. I should have some time to try these suggestions out over the next few days and I'll report back. I did think I could probably make a nice digital rev counter using an led and ldr + microcontroller

Hi, thanks for the responses. I'm aware of the need to rev the engine and do this just after I start the engine. The red light goes out and stays out until the engine stops. I haven't been home since yesterday so still haven't checked the engine/alternator model. I think the engine is made by Perkins. How can I check the rpm of the engine and alternator? There are no dials or gauges for this. The person who was on the boat before me claims the batteries charged fine at idle which is what made me think it may have been a slipping belt.

Hi. I'm trying to troubleshoot a problem with the alternator on my narrowboat When the engine is idling the voltage at the alternator is low, around 12.5 - 12.7. Afaik it should be something like 13.8 - 14.2. Is this right? Does anyone have a list of things to check to start narrowing this down? I'm not quite sure how the to check for a slipping belt but suspect that's worth a look. Let me know what info would be useful. I'm not sure what the alternator is but will check. Thanks Will edit - sorry, realised in my sleepy haze that I might not have been that clear about something. To start with, I'm only assuming that the alternator should be charging properly at idle. At higher rpm, the voltage goes up to around 13.9, and the batteries charge. I've just been told that I should not need to do this

Thanks. Will check them out
