    I bought mine (for a standard K series) from Classic Silicone Hoses and would happily do the same again. Lots of alternatives in the archives and most people recommend whatever they bought. Jonathan Edited by - Jonathan Kay on 19 Feb 2013 19:01:04

    On mine it's 75 Nm. Jonathan Edited by - Jonathan Kay on 18 Feb 2013 09:00:08

    PS: It's MFRU. If you've got this problem you might be surprised that the F stands for "Function". Jonathan Edited by - Jonathan Kay on 17 Feb 2013 17:25:31

    Keep going... there's lots more. And have a look at this from Alcester Racing 7s. When you've done a bit more diagnosis and had a look at the fix you need to decide whether to: 1 Do it yourself 2 Ask BC for help: some members are very helpful 3 Take it somewhere and pay. Jonathan

    There's lots on this in the archives. 1 What is the battery voltage before cranking and during cranking? It's important to be sure that your battery isn't on the way out before going to 2. 2 Search for "Click" in the archives. There is a widely-described fault where the relay doesn't deliver enough current to the starter. There is a simple fix. Where are you? Jonathan

    Thanks. Years ago we used to use classical electromechanical meters. I've still got a pseudoAVOmeter on my shelves. Now I use a cheap (<£20) digital multimeter: I've often wondered how accurate it is. Jonathan

    Quoting weeman: ... I've had a Fluke multimeter... unerringly accurate.How do you know it's accurate? Jonathan

    Snap! Jonathan

    ... this the right manual? Jonathan

    Quoting LazerBrain: JK - I made an equivalent to this current tester to connect to my DVM, which allowed me to measure the current flowing through a particular fuse. Obviously you need to take care not to overload your meter. My testing did not require the engine to be running - switching ignition on/off was enough to trigger the fault condition.That's neat. You could put a protective fuse in series in case you plug it in a high current fuse holder by mistake. I don't have a leakage problem but it seems to come up quite often. Jonathan

    Can this type of meter measure DC current at the level needed to diagnose slow discharges/ immobiliser problems of the type frequently suspected on 7s? Thanks Jonathan

    As above, for most uses on cars you don't need anything fancy. Audible continuity testing saves time. A robust case is a good idea as it's going to hit the floor at some point. Leads with small spring clip ends are useful on the bench. I use a Draper, something like this. Jonathan

    New battery sounds sensible. But do take the opportunity to inspect and clean all the contacts in the starting circuit. Jonathan
  14. Jonathan Kay
    I suggest you measure the battery voltage at rest and on cranking and report back. Jonathan

    Nod off? It's fascinating: please keep it coming. Jonathan

    Thanks, Ian Jonathan

    I cut the hardboard (or ply) to fit between the radiator brackets, and fixed the batten to the top of the hardboard with enough overlap to rest on the brackets. Nothing touching the wall or damaging the paintwork. No need to remove the radiators. Jonathan Edited by - Jonathan Kay on 2 Feb 2013 13:36:35

    Don't know anything about those specifically. But you can save a lot of heat by insulating the wall behind radiators. Lots of pictures showing this using heat-sensitive cameras. It's easy to make your own with a batten, some ply or hardboard and aluminium foil. Jonathan

    I put mine in the bulkhead in front of the passenger. Sounds similar to Roger's. When I put a horn button in the dash I used a sheet metal hole punch. I thought that would be easier than drilling. Any experts who know the advantages and disadvantages? Jonathan

    That one looks good. It occurred to me after posting that it might be possible to design a single cut-out that could then be just folded differently for different batteries. A bit like the different size and style lines in dressmaking patterns. Jonathan
  21. Jonathan Kay
    How much demand would there be for some simple battery case/ brackets? The only ones I can find are very expensive. If we could get these as jet-cut flat aluminium sheets with added lightness and marked for folding would anyone with the equipment be prepared to fold them for others? Jonathan

    Doubling the number of horns doubles the power. Doubling the power* is a change of 3 dB. Jonathan * Or "power ratio" if you insist.

    Thanks. That's great information. Tethering would be very useful but of course there's still the data limit. Have you ever found out if the EU cap on roaming data charges works in practice? Jonathan

    Quoting skydragon: I've got a iPhone on a 25MB a day data tariff which works throughout Europe and I use to teher my laptop to, but I usually buy a 'local' USB dongle for less glamorous destinations outside EU...I have a friend who is looking for something like that to use in France: could you give the details, please? Jonathan

    As above + measure the voltage at rest, and across the battery when cranking, and across the starter when cranking. Jonathan
