    ... 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

    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

    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

    I have a 12 year old niece who lives in Chile. She's getting interested in photography. Does anyone have a used Canon digital SLR camera and lenses that they would like to sell? Thanks Jonathan

    Please use a carbon monoxide monitor if you do this or something similar. Jonathan

    What's the setting... general use in an ordinary car? Are you prepared to open the bonnet and put things in and out, or do you need something slicker than that? Jonathan

    When we got to 50 I ordered 75. They've nearly all gone out now. I'll tell you exactly how far down the list we got in the next few days. I think there are already about 11 further requested. Who would like one or more? Jonathan

    Quoting the.vet: I've now measured the threaded shaft - 10.3mm outside diameter. Threads/inch appears to be about 14 but I'm not very good at measuring this. I'm now wondering if I've got a weird size or have I been sent the wrong nuts... Sorry for mixing old and new measurements but as a child of the 80's, I'm neither fluent in imperial or metric There's an app for that Jonathan Edited by - Jonathan Kay on 16 Jan 2013 16:57:58

    This was discussed recently: should be in the archives. This might be what I remember. Jonathan Edited by - Jonathan Kay on 16 Jan 2013 15:08:05
