We got a text back from Cart this morning and the lady said the bottom pair of gates are going to be replaced in November's stoppage. I hope the paddle can be made to work meantime
-
Thanks Mike, we did try closing the gates after escaping and they didn't look much different closed either way.
We helped the next boat through with our carpet and then the third boat owner turned up with a barge pole about 2 1/2" dia which he said he stuck down from the top on these occasions. Also worth knowing about.

Good Morning, we have just had great difficulty getting through this lock due one to top paddle out of action and big leakage between the bottom gates. I've tried ringing Cart but still too early, we'll try again later.
We ended up using a piece of old carpet and a pole to bock the gap.

Last week we got to the top at Crofton just as the guy had locked the gates for the night, so we had to spend the night there. We had an interesting walk after the rain stopped. I started wondering why the banks are so high when there is actually plenty of water in the summit pound?
Also, there is enormous headroom through the Bruce tunnel. Was this to enable the top pound to be kept very deep in order to create a reservoir?

It might do, but we are not on mains at present, thanks

Thanks all for the excellent advice, I'll be back on board on Friday and not use it until checked. Also thanks for the safety tip..

On our boat we have a Victron phoenix multi plus inverter 12 2500 120 and seem to have a random fault which cuts it out maybe once a day - all three red LEDs come on at once - Overload, Low Batt and temperature. It is in the engine room (not ideal, I know) but has not been over 40 °C since last summer. I plan to rig a fresh air duct to feed air in below it before this summer. I don't see this fault in the manual I have downloaded (can't find the actual manual on their website): https://www.victronenergy.com/Manuals/PhoenixMulti/UKISM010004000-rev08.pdf
Anyone have experience of this, please?

it looked to be very strong wth no insulators. a lot of effort for a hammock, though.

We came south through Braunston on the Oxford today never passed as many moving boats in my life! Just north of Braunston we passed a boat which has stayed in my thoughts all day, I wish I had stopped and taken a picture. It was grey I think, 50' long ish and was very tidy but had a very strong, well made sort of washing line high above the roof between two strong stayed masts.
Anyone know what that is about, please?

That periscope film about PLUTO was absolutely fascinating, what an acheivement! Thanks for sharing.
Cheers

It is a dark place, but we have had no trouble there leaving ours in summer, but its probably quiet at this time of year. Glad they didn't get in.

15 minute walk to Preston BUS station. Train from Preston to Burnley.
We live near Preston and have found out that ALL the Eastbound busses running over the road bridge at the North end of Preston railway station stop there and will take you to the bus station. You won't have to wait long for one to come along.

Fault tracing is all about testing stuff and proving it works,
Right I'll have a look at the brushes but the other day when I shorted the green wire to ground there was loads of power going through

Have you checked the brushes on the Alternator?
It was new less than 12 months ago. I have just bought the top one off eBay thanks for all your help I'll report back when I have tried it.

It looks like the Adverc is not working
It is beginning to look like that. I have another of the same model on another sea boat, so I will see what that does at weekend when we launch it, and then try swapping them over. At least they are made in Wolverhampton, and are repairable.
-
I have checked again where the red adverc wire goes and it is to the domestic isolator switch right next to the battery.
I'm afraid turning the pot seems to make no difference i.e. 6 turns clockwise then back. 12 x anti clock then back. And the voltage remains at about 14.3.

s this to confirm that it is correctly wired to the correct place inside the alternator
Yes, and I won't make a habit of it.
Will try the pot adjustment tomorrow, thanks.

The Adverc light should not flash, so something is wrong
It wasn't flashing with the bulb in series.

The 14.8 comes from the Trojan data sheet, though I have spoken to Trajan about getting them quickly charged in winter on a liveaboard boat and they suggested giving 15volts a go.
I have the Adverc set to 14.8 volts on its higher voltage. I top the batteries up at engine service intervals which is 200 hours. However in summer when we are doing longish days almost every day I drop down to 14.6 volts.
Four of my Trojans are now at the end of their life and use more water, and at the last 200 hour check the tops of the plates were just peeping out at me, but these are 6 years old on a full time off grid liveaboard.
"OK to carefully short that fly-lead to the alternator case with the engine running while watching the battery voltage"
I'm back at the boat now and have just done the above with the battery at it's highest voltage - 14.3. It immediately shot up to 15 or 16 and the adverc lamp started flashing. There seems to be a lot of current going through the green lead so the next time I did it through a 10 watt 12v bulb. The bulb glowed normally and the voltage climbed to 14.45 and now remains there.
I have had the back off the adverc and the pot is obvious so now I propose to turn it clockwise a couple of turns then try again with green lead connected?

you can temporally connect the fly-lead to negative with the engine running with well charged batteries and the charging voltage should go jump up
When I get back to the boat I shall disconnect this fly lead and measure the voltage on it with engine running through start-up to full voltage, that might tell me which side of the rotor it is connected.
The red Adverc sense lead is extended right the way to the battery + terminal.
I have rung the new alternator supplier and am going to send them a photo of their connection in it and see if I can change it, alternatively take it back to them to do it.
Luckily, I have a spare standard alternator that I can fit meantime.
"Once the Adverc is working you can persuade it to boost the charging voltage by putting a couple of diodes is series in the sense lead". that sounds like a good idea, I'll get some ready to take.
"Trojans like about 14.8 volts so the Adverc should provide this during the high part of its cycle." that is what I now aspire to, in order to keep my 4 new babies thriving.

The Adverc should have its own indicator lamp in addition to the standard ignition lamp. This should be on before the engine starts and will flash to indicate (some) faults.
Yes, it does have one and it acts just like the ignition lamp, and it is the left hand lamp on the box I added with the bypass relay below, and the one thing that changed when I fitted it was that the alternator kicks in immediately the engine starts rather that as it was before when I had to rev it a bit to clear the ignition light:

So after about an hour or so, longer with very discharged or faulty batteries there are no signs of the charging voltage and current moving up and down at roughly 20 minutes high and then 20 minutes low.
Thanks, Tony for an easy -to - understand explanation, I'll go through it all later and ring the people who modified the alternator.
No, I have been watching for the Adverc cycling it, but it doesn't.
It must be a negative controlling Adverc according to its label:

I have never pulled my priming levers past the point where they start pumping as they felt rock hard and I thought I might have be going to break something. Are they normally hard to pull? Engine is a great starter always.
