    Have you already got the gaiters? Jonathan
  2. Jonathan Kay
    More on this, please. IIRC I gave it all a slathering before hiding it away again. Jonathan
  3. Jonathan Kay
    It's good to hear that they've reappeared. Otherwise as Ian suggests. Jonathan
  4. Jonathan Kay
    Photos, please. I don't understand either how many variants there are or how the hose exerts load on the hose stub of the radiator. Jonathan
  5. Jonathan Kay
    What matters for those brackets is avoiding any load on the radiator as it's attached and tightened up. Mocking it up somehow or other is a good idea but after that it would be lighter and simpler to make a custom bracket with fewer fasteners. If it involves fabrication there are some very helpful, skilled and generous Members... IIUC you could use the existing bobbins by taking up the extra distance in the bracket rather than with a longer bobbin. Jonathan

    Usual request: please could upgraders take some photos down the road to show the illumination before and after. Probably easiest done by changing one side and then taking photos with one side masked at a time. Thanks Jonathan

    Jonathan PS: Always happy to discuss searching...
  8. Jonathan Kay
    Yes. Also in the other Assembly Guide! Jonathan

    What BigCol says. This is described in the text-rich version of the Assembly Guide, along with much else that isn't in the current pictorial version. Please let me know if you'd like a copy. Jonathan

    It was achievable with pretty simple modifications to petrol engines. The supply chain for the fuel was already in place. It did reduce some types of emissions (but increased others). And it avoided some taxes. Jonathan
  11. Jonathan Kay
    Thankyou Jonathan
  12. Jonathan Kay
    What's the current (!) cost of the added lightness? Jonathan
  13. Jonathan Kay
    Thanks for the photos. A jack in the engine bay, but it isn't mine: Jonathan

    I have a couple of Volvo child cushions that can be used as inserts, although I think that they are older designs than that. They fit well in the standard seat, and the belts are OK. One of them was also sold by and badged as Ford. Part numbers in the archives. Jonathan
  15. Jonathan Kay
    Thankyou Jonathan
  16. Jonathan Kay
    What make is the starter? (I'm sure that you followed the investigation into transients with Brise starters.) Does the ECU drop out during this? Thanks Jonathan PS: We might be approaching another look at cheap oscilloscopes...
  17. Jonathan Kay
    I've had good responses to emails: reasonably quick and exceptionally helpful. There are reports of delays in the archives. Jonathan

    I haven't heard of any problems with this on the many Sevens that have Powervamp/ Odyssey AGM batteries. If you use a smart conditioning charger it's probably sensible to use one that has an AGM mode. (But I don't know what would happen in practice if another setting is used.) Jonathan
  19. Jonathan Kay
    Me too. Are you thinking of a bit of angled sheet bolted to the block and acting as a barrier between the starter motor and the exhaust but leaving the starter motor fully exposed? Thanks Jonathan
  20. Jonathan Kay
    Professionals have load testing kit that can measure the voltage and current at high current. The "minimum voltage during cranking" is a poor man's version of that, using the starter motor turning over the engine as the load. That can be done by any owner, and I don't know if the professional kit would add anything. And DIY means that you can follow it over time, and get an early warning of deterioration. I'd recommend doing that in the same way as checking oil and water (and battery fluid) levels. Jonathan PS: There isn't an offer of that kit in the equipment register, and i don't expect one. But we could do with some high voltage equipment to help with testing ignition systems...
  21. Jonathan Kay
    Thanks for the figures. I'd fit a new battery. I try to keep that "Best battery" thread up to date. All additions welcome. Jonathan (Sealed batteries only in my cars)
  22. Jonathan Kay
    Checking the drive belt condition and tension is a good idea. I wouldn't worry about the 13.95 V beyond that. Jonathan
  23. Jonathan Kay
    "This is a quick DIY method for testing how the battery behaves under load and whether the car's charging system is working. "The minimum voltage while cranking (the convenient DIY load) should be greater than 10.5 V. As well as measuring the condition of the battery this may help to explain what's wrong with the car as electronic components, including the ECU, can drop out below this. (The surprising thing is that this can happen although the cranking speed seems fine.) "The voltage at 3,000 rpm is a test of the car's charging system, and should be greater than 14 V." Jonathan
  24. Jonathan Kay
    That voltage during cranking is far too low. Did you charge it after topping-up? If not I'd do that now and retest... but I expect that you'll get a similar result. Jonathan
  25. Jonathan Kay
    I'm all in favour of thread resurrection. : ) But have you read John Vine's exploration of fuel tanks? Jonathan
