  1. Adding fuel to the fire, today it was reported that a parliamentary group has decided that increasing the bio content of fuel from 5% to 10% is a "no brainer" in light of the increase in CO2 emissions from new road vehicles, due to the flight from diesel to petrol. I guess it will increase cases of bug in our fuel whatever colour.
  2. Piece of 6mm perpex, carefully cut holes to fit instruments (it cracks) then get labels printed and placed on the bottom side, you need 'backwards' print so you can read it. Then cover the whole back with sticky back vinyl, gold looks like brass, and silver looks like polished steel. Cut the holes in the vinyl, after stretching flat, with a scalpel. Mount with a bevel edge (look at picture frame) moulding, put instruments in holes and wire up, your done.
  3. I would check the panel first. There should be 20 volts between the terminals and when connected via an a meter you should see a few amps on a sunny day. It is highly likely the panel is duff, stuck down panels rarely last more than a couple of years. It will not be enough to run a fridge but if good will cope with lights and pumps.
  4. Goat chains. Can't be shaken or snatched out. Also much quieter no clank clank as boat moves.
  5. With that air draft. Check if you can get through Nottingham I seem to remember a fairly low bridge. From Nottingham down the trent fine.
  6. I have found that CRT employees are generally helpful knowledgeable and very good. Not all wearing CRT shirts/jackets are CRT, some/many are volunteers who rage from very good and helpful, to like to sit and watch the boats and don't help, to little tyrants who know best and you will do it their way or else. Contractors staff on the other hand will probably be on minimum wage, zero hour contracts, so they want to make the job last and have little incentive to use their initiative, if indeed they are allowed to. They also have no idea if they will ever be back to the location so have no ownership.The other year I was going through a lock in winter and there was a man pointing the bridge parapet, it was below freezing and only going to get colder. We chatted and he said he knew it was a waste of effort, he then pulled out his phone, took a picture of the work to send to his boss, to show he had done the work scheduled by the 'system'. later four months later we saw that the pointing had been redone that day so the first effort was indeed wasted, but contractors do as they are told, no more and if they can even less.
  7. Interestingly suggestions that slowing down will cut pollution particularly with ships. They already go slower than they used to and the speed is dictated by the balance of cost of fuel (faster uses more per hour) and the time between ports (crew cost) they have sophisticated computer models to work this out. Maybe we will all get allocated lock times and have to adjust our speed accordingly. I have seen a rapid growth in 20 MPH zones ostensibly to reduce pollution, but does it?. My car requires the use of a lower gear at 20 MPH than it does at 30, engine revs are virtually the same, surely the volume of engine emission is linked to the RPM maybe with a little bit less nasties due to not working so hard. But I take 50% longer to traverse the 20MPH zone so the volume of exhaust is actually higher! Still these people know their science, or are they arts graduates who find maths and science to hard.
  8. Could it be something to do with the Victron periodic equalise, that battery getting fractionally higher volts than the next, and the next even less and so on.
  9. Can't see RNLI being happy with battery boats unless they can do 25 knots for a few hundred miles like their current diesel fleet which are built to last 50 years. I also can't see the required investment in canal side charging points even if there is enough electricity to supply them as well as the electric for home heating, car charging, office heating and everything else.
  10. Prize goes to those who suggested earth / negative. An example of why soldering on a crimp eye is not good. My hull connection like many goes onto the engine bearers, unfortunately when climbing around in the engine bay they make good foot holds, result a lot of flexing of the cable. This had 75% broken inside the black sleeving, so it looked good, felt fine ,but wasn't up to the job of carrying the starter current. Thanks for your help.
  11. My compartments bone dry, it does have a bolt down watertight top in the well deck though.
  12. I assume CRT have measured the boat, because not all builders use the same tape measure. My boat is supposed 57 but is 56.9 my friends boat is also 57 but is 57.8 long so there is a big bit of stretch in builders tape measures.
  13. Almost done that with jump from old battery to starter contact started fine that is when I decided to bypass the isolator as basically that was the only difference. My memory isn't that great these days so possibly still had new battery connected when I jumped to starter which would make more sense. She who must, is now demanding coffee and cake so I shall give in and sleep on it
  14. Yes the meter only goes up to 300 and shows OL so I know that it is above 300 amps but don't know if it is 400 or 600 for example. If there was an earth fault surely we wouldn't get the current flow we do, similarly if it were the solenoid or brushes why would doubling up the cranking amps with two batteries have the desired effect. It seems as though the engine is taking more power to turn it over, strangely enough this did start after I got the most enormous teddy bear round the prop, it didn't stall the engine but made it cough and I stopped it, then it was hard to start, probably the last time it did so on one battery. But as said the engine is in neutral so I can't see any connection.
  15. I had problems a few weeks ago starting the Isuzu 42 engine, if I jump leaded from the domestic started fine. Got to the marina went home got a new battery 950 CCA so far so good. I have fitted it and again it won't start the engine unaided I can jump lead domestics or the old battery and instant starting. The alarm goes as normal when the key is turned in all cases, there is a clicking and the engine tries to turn on one battery, on two batteries louder clicking and engine starts as it should. I have checked all joints, unbolted cleaned and rebolted, and bypassed the isolator to eliminate that. The old battery was 7 years old and 1000 CCA. Someone has mentioned starter motor bushes, any other ideas. I understand 700 CCA is the recommended battery by Isuzu. Volts drop to 11.6 at battery not sure about starter motor end, the clamp meter snows overload on the 300 amp range so something is making the engine hard to turn, and it is out of gear.
