Travel power - doesn’t work, can anyone help?
dmr replied to kingbillymatt's topic in Boat Building & Maintenance
Turnbuckle, eBay, I think the shop is McGill Motorsport. They look good and work well. They don't provide any axial restraint like a conventional strap, but mine has worked fine for maybe 10,000 hours so I am happy. I suspect on some alternators there might not be enough clearance to get the rose joint in and aligned with the bolt hole. -
Maybe the Red Lion at Cheddleton? but looking at the www it looks much posher than I remember it. Can you still get the Badgers Arse? it as very good.

dmr started following Narrowboat stove flue, coming out of sidewall. , Caldon canal and Travel power - doesn’t work, can anyone help?

It was all a long time ago and a bit alcoholic, and on the way back your mate turned up with a large quantiy of west country cider. I think we went into the Foxley but there was also another pub further on, I can remember a bit about the inside but little else, ill have a play wih Google Earth and see if I can remind myself.. We all went through the tunnel in your boat and it fitted easily. To the op....its a lovely canal with a lot of variety and interest packed into a relativelt short distance.

dmr replied to kingbillymatt's topic in Boat Building & Maintenance
I think mine is nicer, but there is much less room on the other side of the engine to do the same on the TravelPower. -

I have exactly the same issue, and a similar bit of wood. The belt wrap is not good so getting just enough tension to stop the squeal is quite difficult. Pretty close to the top of the todo list is to make a better tensioner based on a turnbuckle (like what the rally people use for adjusting suspension) but I can't find a good convenient mounting point on the engine so a difficult bracket might be needed. I believe Ed sells a freewheel pulley upgrade that might or might not help the squeal. Looking at his website he is a busy man these days and has turned his attention to lithium installs and big alternator upgrades, so Cox might be a better bet as he does a quich turnarround, but you really need to take the travelpower him (walking distance from the canal at Atherstone). The brushes are a fairly easy job to do but the bearings do need replacing routinely, though this mostly applies to the old "blackbox" model. If you neglect to do this they will fail and the rotor will hit the stator., I know this 😀. -

There you go, working under a bit of influence can be quite productive as long as you don't overdo it. 😀 -

Thinking about that green light a bit more ... 😀 On my blackbox travelpower that green light only comes on if the Travelpower is working and the voltage is good, if it gets loaded too much (at lower speeds) then the green light goes red, so that light must be actually monitorig the output, its not just any old green light 😀, so if the light is on then its almost certain that the Travelpower is working and the problem is within the wiring, switch, or Victron. -

dmr replied to kingbillymatt's topic in Boat Building & Maintenance
So it sounds like the Multiplus is handling the switching of the Travelpower to the mains wiring. I don't know anything about the Victron, can anybody on here help?. Note that the Travelpower is unusual (or at least the old blackbox model is) in that it does not produce a conventional 240 volts but instead makes 120 on the live and an out of phase 120 on the neutral. Is it possible that somebody has got the neutral-earth bonding wrong? -

dmr replied to kingbillymatt's topic in Boat Building & Maintenance
If the green light is on then the TravelPower is likely working. Its possible that the mains wiring, selector switch, or some clever electronic switch inside your inverter (if you have one) is to blame. If you are confident with mains electricity and have a multimeter then you could measure the voltage at the TravelPower box (if you have access). There are few people about who can fix problems with the alternator, if it turns out that the Travelpower silver box has a fault then Cox Auto electrics at Atherstone are probably the only people who can still fix them (he did mine about two weeks ago 😀). -
Narrowboat stove flue, coming out of sidewall.
dmr replied to 19Granny66's topic in Boat Building & Maintenance
Maybe the stove was relocated and it was discovered that there is wiring above the roof lining? Assuming no such problems it really won't be a huge job to sort this out. Those who have the skill to cut and weld steel make surprisingly light work of this sort of thing.- 66 replies

Cell phones innit? 😀 I reckon you know all this, but the whole country is divided up into little regions or cells, otherwise there would just not be enough bandwidth (radio frequencies) for the number of mobile phones. Each mast can have several cells going off in different directions (or even overlapping) and they are of variable size, bigger in rural areas. I guess the mast uses clever aerials to control the shape of each cell. So, adjacent cells will use different frequencies but a cell a bit further away can re-use the same frequencies. My fancy router tells me which cell I am connected to and then I can look on the interweb and find out where te mast is and the shape of the cell. I like "cellmapper". Its interesting that it says I am just outside the cell but I get a very good signal. My smartarse router also gives me signal strength and various measures of signal quality. I've wasted whole days of my life looking at all these silly numbers. and forgot to say, the Wagon and Horses appears to be the local Sunday venue but its not my cup of tea (oe even pint of beer), did you try it?
-
There aresome very obvious patterns to all this. Up here Sunday late morning and afternoon are bad. Our cell is mostly residential rather than work so I wonder if everybody watches films on Sunday afternoon? or maybe its all the eBay bots 😀??. Very late at night is a good time to get really good speeds I don't know what the capacity of a typical cell is, it would be interesting to know how many people doing huge downloads are needed to slow things down.
-
I still reckon there is the "new customer bonus" on new contracts. Once youve written a good review and told your mates how good it is then the speed will start to drop off 😀. The experts here tell me this is not true but I have seen it happen several times. Boat next door has just got a new Lebara sim and was seeing an 80meg download speed.

I appreciate that 2.4 has better range but lower speed (and more prone to interference), I need the range which is why I did not choose the 5GHz router. I also appreciate that the router does not prioritise any device (though my wife suspects that I have found such a setting😀) but it really does appear (from first hand experience and testing) that some devices get a lower performance when sharing the WiFi, the challenge is to understand why this is. I've just had five minutes playing now and my phone is faster if there is no other active (but idle) Apple device in the boat, but I need to repeat this tests lots of times to get a statistically significant result. Lebara doing 49/21 on the PC right now.

We got the lower tech Teletonika router as its "always on" and I read somewhere that the new higher spec one uses more power. We need wifi right through the boat (sofa at the frint and bed in the back cabin) so I assume that 2.4G is the better option. Maybe I should have got the better one and put the PC on 5 and the Apple stuff on 2.4 (if that is even possible). There does appear to a bit of a pecking order when two or more devices share WiFi and the Windows PC always comes out on top., but even with the PC off the Apple stuff does not match the speed of the PC
