  1. Just to amplify that a bit. You need the terminal voltage of the batteries. Buy a cheap digital as Tony suggest but run a pair of thin wires all the way from the battery bank to where you sit. Battery bank connected to one end, voltmeter connected to other end. Virtually zero current drawn therefore no voltage drop. Simples? N

    Confession time: Te threads have been stripped for some time. What I did for the last couple of services was to insert some bits of fine copper strands stripped out of scraps of wire that I had. They worked fine but I thought that there might be something a bit more refined. Thanks for all the suggestions. The problem with buying old jobbies to canibalise is that they might have just the same threads stripped!. N
  3. Done that. Thanks for the email address. N
  4. Here's my contribution sent to editor@canalboat.co.uk: Dear Sir I would like to add my voice to the protests about the appalling behaviour of your contributor. With manners like this he is not a worthy representative of the magazine that you work for. My comments refer to the evidence on this YouTube video: http://youtu.be/ldoVS0idTBw With boat handling like this he is not fit to offer advice to anyone, especially the novices who might be reading your magazine. Here are some of the more obvious mistakes that he made: Passing ahead of the large white boat seen in the distance. He should have left this boat to port and turned under his stern. Failure to appreciate that on a first come first served basis the cruiser from which the video was filmed clearly had precedence. Approaching a mooring while running with the current. The correct way is to turn and approach while stemming the current. This gives best steering with minimum speed over the ground. Deliberately ramming the cruiser as evidenced by his operation of the tiller. Putting his partner at risk. (She was standing on the gunwale during the deliberate ramming.) I look forward to hearing your comments. Yours faithfully N A Cooke Just noticed the date of the original post! Methinks I am a little late in making my thoughts known! N

    Thanks, Mr D'arth. Drilling and rethreading would seem the most satisfactory way. I had heard (read?) that you can insert a thing like a spring into the hole to produce a new thread but I suspenct that this would mean drilling out a larder hole and rethreading with a tap would be much more satisfactory. N
  6. I have a this here heater which has done valiant service for the past 15 years. I have occasionally cleaned the glow plug and once or twice cleaned the flame detector but now I have a problem. The two cross head machine screws that hold the glow plug boss in position have stripped the threads of the alloy casting into which they screw. Ditto a couple of the hex machine screws that hold the fresh air fan assembly to the alloy body. Is there a sensible way of sorting out this problem? Nick
  7. I wholeheartedly agree. We did it oursleves the last time and would have saved ourselves a lot of trouble if we had done the same again.
  8. Thanks all. This all confirms what we know is the case. They have done a really rubbish job! Now we need to decide the next steps... Nick
  9. Reply to Mr Cuthound: Would you be willing to say how much you paid and who did the work? N
  10. I could possibly say but we are moored at Tardebigge Old Wharf and the boat yard, which also hires out lots of boats (reasonably painted) is the closest one upstream from us. Nick
  11. Sorry, error: It was only the cabin that they were supposed to take down to the bare metal. N Only the cabin. I said the wrong thing in that reply. N
  12. About as naff as they come. And one of the staged payments was to strip the hull down to bare metal! I don't think that I bothered to take a larger shot. It looks OK from a distance.
  13. When we bought Theodora she was soundly painted in a plain maroon colour. We didn't like that much so I prepared for a new paint job merely by keying up the topcoat (There was no rust.) and SWMBO set about painting her with undercoat and top coat. Very nice she looked and after five years she was still looking very good. After seven years she was begining to look scruffy and after another couple of years we decided to have her professionally done. The instructions that we gave were that we didn't want a high gloss shiny job. That was not our taste. We paid a booking fee and then lockdown came. We paid a couple of staged payments but could not inspect the job because of lockdown. When we eventually were able to inspect the finished job we were perturbed to discover much that was wrong with the way that the boat had been left dirty and untidy. Things had not been put back. The MPPT controller had been destroyed because the electrician didn't understand how to wire up the panels and much else... So far I have not paid the balance but am negotiating an agreement where the balance is reduced according to how much work I will have to do to reinstate poor Theodora. In addition, because the paint job is suspect I am going to require the yard to give me a written guarantee that they will repaint her if, as I suspect, the rust comes through in various places. I have attached photos of some of the suspect areas. The wording of the guarantee (if that is the correct word) will state how long the paint job should last. This will be the length of time that the guarantee will last. So my question is: If you have paid thousands of pounds for a paint job, how long would you think it should last until a few rust spots appear and how long before a complete repaint will be needed? Nick
  14. I think that jump leads may be the way to go, but I must test the starter battery. The whole set is very old! Thanks for all the help. Nick
  15. Having fitted the new Victron controlle as advised elsewhere and discovered that it is vey good and done an experiment or two I now have some answees and another question. I tried fitting connecting the output from the MPPT to the alternator/engine battery side of the relay. This should have meant that the Smartbank advanced woould have treated the solar panels as a normal charge source and charged the engine battery in preference to the domestics until it was fully charged. At that point it should have energised the relay and included the domestics. Smartbank certainly tried to do that but at times the charging current was so low that it did not energise until Smartbank Advanced's "Hold" function was activated. It would hold for a few minutes and then deenergise the relay for another few minutes then go on to hold again. The result was that the intelligent charging feature of the MPPT got really confused by the repeated changing of the battery bank size from 90Ah to 600Ah. The MPPT would go on to different charging regimes (absorption, bulk, float) when what it really needed was to stick with bulk. I have now changed back to Gibbo's recommendation to connect it directly to the domestics and all is well except... ... for the fact the the solar panels no longer charge the engine battery. This is a nuisance. Dow anyone have any thoughts? Nick
  16. If I recall correctly lots of mooring rings were installed, then a person tripped over one so they cut them off and now you can't moor! N
  17. I think that it was on the Middle Levels prolly close to Upwell. N
  18. Hm... 900kVA. Do I run a mobile paoer station on a narrowboat? 900VA it is. Nick
  19. I have just looked up my spreadsheets and find that for my Kipor rated at 900kVA I have been getting an average of 87 hrs per 13kg bottle of propane. HTH N
  20. That's all very interesting. Perhaps I won't add that to my list of complaints, which, I have to say, is rather long. N
  21. I am coming to that conclusion but will open it up at home when we get back. Living without a fridge in this weather is not easy... But we are going along with no. 1 son and family on their hire boat and that has a workign fridge so life is still pretty good. N
  22. There was welding work. The solar controller can be explained by the wong reconnection as described in the other thread. The inverter has been showing signs of failure for a bit even before Theodora went in for painting. The indicator light had been unreliable and there was an occasional beep from it. It was working after the paint job and survived until 5 days into the present cruise. All the fuses looked ok but when I tried to take them out (they are 35A rated) i needed pliers to remove most of them and then broke the holder when removing one of them. It rather looks as if even if it was repairable before it no longer is. 😢 N
  23. Thanks. I haven't checked the fuses! I will do that next but since the fault has been gradually appearing over the years, starting with the indicator light not working, I don't hold out much hope. I'll be back... N
