The Ents

Hi Bod'sSR2, Our SR3 has 40 psi(g) cold but when hot drops to 5 or 10 psi idle, 20 psi at revs using 15/40 Morris oil. Some years ago I checked out the crank and B/E bearings. They were fine, the crank showing no ovality or undersize i could measure with a normal mike in the confines of the crankcase. Stop worrying, I think if I were you I would stay with the warning light! Mike on Balthazar.

Just drov e under that aqueduct and the leak has reduced considerably. It always has been a bit damp, give it a while and it’ll be acceptable, I guess. Ic e was not a problem last week. The road aqueduct is maybe 100 yards East of the river aqueduct where the breach occurred. Mike.

Wow, that is food for thought. Thank you. So what would be the fix for that? Silicone spray? Mike.

Yep!

Yes guys you are correct. The RCD at the supply into the marina is rated 100ma. My error I’m afraid, should have gone to specsavers.. But interesting meeting with the Electriciam. He first tested our bowt which passed with flying colours! Yippee! at that instant the whole marina tripped! (Yippee, but I didn’t say that.) with our boat not connected. So this poor bloody electrician has a real problem. The boat next to ours has a shoreline plugged into a galvanic isolator and the euro plug is full of rainwater. He disappeared and changed some RCD stuff and unplugged other suspects’ boats. Later, much later, he came to our pod and tested the earth which was OK at 60ohms. However as soon as he put his tester into our pod socket and began to test the RCD at the pod the main RCD at the marina tripped at a very low current, I couldn’t see what sadly. Sorry. So we have what my dad would have called a right pig’s ear. I left the poor fellow still working his socks off at 4.30pm! At least I know it is not our bowt! I must thank you for your comments so far and look forward to reading some more of your thoughts this evening! Mike.

That would be interesting. I shall try to. Mike.

Yes, it all somewhat backwar in priorities i think.The Electrician is coming to the marina tomorrow....

I think the only thing the marina manager would let me plug into is my,erm, sit upon!.

Ah. Forgive my ignorance. Mike

Yes, I believe the RCD on the jetty, each jetty has its own RCD as well, is class A and 30ma, the one for the main marina is class B and rated at 10ma. Mike.

On my Pod/Bollard there is a trip, I assumed it was just for current overload. Are there circuit breakers that do both residual current and overload? Mike

The DC currents which trip class B RCCBs are generated maybe by motor speed controllers chopping the frequency or perhaps a smoothing condensor leaking to ground (look I am just reading from ‘tinterweb, I do not necessarily understand.) Mike

Good question. When trying to reset the trip it would not reset, just flipped out again. They then isolated the jetties one at a time until it turned out to be my jetty, and so on to my pod. There are two boats on this pod, only mine was connected. QED. But I have never managed to make it trip, only at 3.30am when I’m not there. Mike.

I hope not to be sloping up or downhill! Yes, first thing I did was to make up a new shoreline. All connectors quite dry. Mike.

Thanks for the replies guys, yes it has been fine for 8 or 9 months, Scottish power fit a new unit and immediately the problems started. But clearly there is some problem with my boat? Mike.

Hi All, My Marina power provider has just fitted a new unit in the main supply. My boat now trips the main RCD at 3.30 in the morning, three days running! Everything goes off including the freezers in the cafe. I am in the doghouse and disconnected from the supply. So where do I start? Yesterday i made up a new shoreline, did some simple tests for shorts with a normal DVM and found nothing obvious. I then had the Stirling inverter/charger working, an electric drill and grinderette working for maybe two hours with no fault. I could not stop on the boat last night so disconnected everything except he Stirling. The boat’s 230v system was not connected. The only thing running was the Webasto diesel heater, programmed to come on at 3am. I guess that was completely irresponsible of me because the marina went off at 3.30am this morning. Maybe when the Stirlings cooling fan came on? Roumour has it that the new RCD is a type B and so will be tripped by stray DC currents which my charger may generate. Now this is quite beyond my skant knowledge of electrikery. Do I now have to fit a new charger? Do I fit an isolation transformer? Any advice will be cheerfully received. Mike.

Yes, well done CRT and the contractors, Keir.

Sorry, don’t know. Original dates were 21/22 Dec,

Glorious sight, the bywash at Wardle running well! Looks good doesn’t it? Not yet open to boaters, there are 3 CRT boats waiting to shift muck and barriers tomorrow. Mike.

Water now only about 12” down, at 3pm today Fingers crossed. Mike.

I apologise for the quality of the image, it was lagging down. Both dams now removed. water maybe 5 ft down, counting bricks on the bank. More on Monday i expect

I was stood by the towpath barrier for the works. It is situated 50ft past the steps down to the Nantwich road. I was maybe 300 yds from the bridge. (A drive and a wedge for me...) Mike

It is the bridge Byron Stanthorn lock. On a good day you can see the lock gates through the bridge ‘ole! Mike.

Same thing, I think. mike.
