No problem. (RatRace recommend using petrol with a higher octane rating in my rebuilt but normal compression 1800 K series engine. I forgot to ask why.) Jonathan

Well done Jonathan

There's a big open area the other side of Horse Guards Road that doesn't get used much... ;-) Jonathan

We haven't got to 25 but I'll buy the next batch from China. If there is anyone who wants one and hasn't let me know please do so by Monday night (29 April 2013). Jonathan

Quoting Jonathan Kay: Advice please: In general do you ever get the potential difference but can't get enough current because of poor connections on low-current circuits the way you often do on the high-current starter circuit?Thanks: people clearly think this can happen. Jason's "bypass with a good connection" method should identify this. I'd use that on both the earth and feed (both upstream and downstream of the switch) sides before changing anything else. Jonathan

I've wasted a lot of time in an MoT inspection and in my garage trying to make the foglight work when the headlamps weren't on and dipped. But I thought that seeing >10V across the unit excluded that... ? Advice please: In general do you ever get the potential difference but can't get enough current because of poor connections on low-current circuits the way you often do on the high-current starter circuit?

Quoting Krismuss: I was nearby today too, round at the IoD! I also worked on 10/11 Carlton House Terrace a few years ago. I was at the Royal College of Pathologists giving a sort of farewell talk, that's number 2. Then we ended up in the bar of the ICA, as I often did in the '70s. Jonathan

*arrowup* *arrowup*Ah, got it Jonathan

That is strange and you've done the right tests. I'd play with the connection of a known to be working bulb in the bulbholder yet again. Has it ever blown fuses? Jonathan Edited by - Jonathan Kay on 27 Apr 2013 17:15:37

Quoting BigCol: ... new sender looked far too difficult to fit... Just to be sure where the fault lies: * Can you disconnect the cable as close as possible to the sender and open and close the circuit and watch the gauge at the same time? * Or measure the resistance from the sender terminal to earth with the engine running and not running? (Can someone who knows more please advise if all electric senders work by varying the resistance to earth?) Jonathan

I hoped this bit might: Quoting Jonathan Kay: From the Assembly GuideConnect the red lead from the starter motor to the battery. Also connect the black lead on the main vehicle loom to the starter motor on the same terminal. NOTE If a battery master switch is fitted, there will be two red leads; one goes to the battery, the other to the starter. The brown lead is already connected. Connect the brown lead from the alternator to the starter. Connect the brown/red wire (covered with black insulation) from the chassis loom to the starter solenoid.

Does this thread and the one to which it refers help? Jonathan Edited by - Jonathan Kay on 27 Apr 2013 10:54:15

Snip at £250,000,000. I happened to be walking past this today. I think it's number 18 that's for sale, but there weren't any signs up. Jonathan

Usual advice: Look at lots. Don't fall in love with one. Take a friend: you've got that covered. Jonathan

Have you fiddled with anything recently? Switch on and off a few times. Any improvement? Disconnect and reconnect all connections to the main light switch. Any improvement? Do you have a multimeter? Jonathan

For most 7s and most other engines in most styles of use I don't think not being pressurised is an advantage. What's the evidence other than the manufacturer's claims for reduced corrosion? There are many people here who have looked at the inside of many more engines than me: is corrosion in waterways a common problem in properly maintained engines? Jonathan
-
My conclusion was: Composition: My guess is propylene glycol + ethylene glycol + some anticorrosion additives + some wetting agent. Not much water. Usefulness as a coolant in 7: No proven advantage. What's needed: A back to back test. Jonathan

This is a good thread Jonathan

Lots in the archives, including this thread. Jonathan Edited by - Jonathan Kay on 18 Apr 2013 18:38:30

Got it Thanks Jonathan

Thanks. I don't think that adds anything to what we already knew or guessed about the composition. Have you got a URL for the full version, please? Jonathan

Bedford K-series noise: induction, exhaust or both?
Jonathan Kay replied to Mankee's topic in TechTalk
You know more about them than I do! I was thinking of it as a diagnostic rather than a therapeutic intervention... Jonathan -
Bedford K-series noise: induction, exhaust or both?
Jonathan Kay replied to Mankee's topic in TechTalk
Could you borrow one of those additional bolt-on cans for the exhaust and see if that solved it before replacing the silencer? Jonathan -
Oil pressure zero then max then bouncing around
Jonathan Kay replied to philmorton's topic in TechTalk
Does anyone know what the readings should be using a multimeter instead of the gauge? Jonathan
