    What SM25T says. It's possible that both are caused by one of those faults. But I don't know what the engine warning light is... Have you got a multimeter (:-)) and would you like a wiring diagram? Jonathan
  2. Jonathan Kay
    Great news. Well done. Now... can we work out a better test routine for sensors than swopping them in and out? Jonathan
  3. Jonathan Kay
    What model and dash... and what's that warning light? Is it the red non-charging indicator that's on before you start and then (usually) goes out? Jonathan
  4. Jonathan Kay
    Thanks, Paul. Jonathan

    As above, but use a GPS device to measure the road speed. Or count the turn ratio of a wheel and the prop shaft. But I'm not sure how that sort of LSD affects this method... Jonathan

    Thanks for posting about the heat shield. That will save others a lot of time. On Jim's point: do you know about the traditional solutions to topping up? From underneath with restricted access. From the cockpit through a purpose-made hole. From above through a non-standard cover plate with a filler and dipstick.I don't think anyone's described which of these are transferable to the Mazda box. Is there a filler plug somewhere? Thanks Jonathan

    Could you add some photos of your current lines of attack... with tools and hands in place? Jonathan
  8. Jonathan Kay
    Phew! I couldn't make sense of those data... Jonathan

    Is a "modine" an oil-water heat exchanger? And there's no separate oil cooler? Does it have a thermostat or any other controls? Jonathan

    It is possible to test some types of lambda sensor in situ with an oscilloscope (or possibly a multimeter). We probably have someone who knows the details... otherwise I'll try and find them. Other than that temporary swaps have been offered by generous Members... Jonathan

    Previous saga. Please could one of the experts advise if judicious use of plumbers' freezing fluid might unstick the joints? Jonathan
  12. Jonathan Kay
    How to check what ratio you've got... ... and which rear wheels? ... and which type of diff? Jonathan (Amended)
  13. Jonathan Kay
    Could you add photos of the fittings? Which "release fluid" are you using? Jonathan
  14. Jonathan Kay
    What final drive ratio are you starting from? Jonathan
  15. Jonathan Kay
    The key question for cruising is the engine speed at 70 mph. It's widely reported that the non-overdriven top in the 6 speed gearbox and commonly used final drive ratios are a problem for that. For the other factors it is worth using a calculator that will show all the engine speed drops. Jonathan

    AMENDED: Crossed post. ... I think it's: 1st 2.69:1 2nd 2.01:1 3rd 1.59:1 4th 1.32:1 5th 1.13:1 6th 1.00:1 Jonathan PS: What's the best online gearing calculator at the moment?
  17. Jonathan Kay
    ... and I am in two minds about whether to stick with the Mazda sourced 5 speed or go with the 6 speed. What final drive ratio are you thinking of? And where in your priorities is relaxed cruising at, say, 70mph? Jonathan
  18. Jonathan Kay
    I don' think there's much experience yet with that gearbox and I can't recall any special hints or tricks. Can you add a photo from underneath of the area around the gearbox mount? (I think it will be a case of wiggling for the best compromise.) Jonathan
  19. Jonathan Kay
    What was the air temperature? Do you have corresponding water temperature measurements? Jonathan
  20. Jonathan Kay
    !!! I can't stand the tension... ;-) Did you ask what went wrong? Perhaps we can help... Jonathan
  21. Jonathan Kay
    Steve: Please could you post details and pictures here. Can I help? Thanks Jonathan
  22. Jonathan Kay
    ... which of those who have posted really use their Seven throughout the winter? It never gets used enough regardless of season! But on motorways and similar on cold days it never gets warm enough. I'll probably just use a bit of blanking rather than a fancier blind*. Jonathan * Or, in my case, a double blind. ;-)

    I assume pics have to hosted offsite. No. You can either link to them on an outside server or upload them to the site. Jonathan
  24. Jonathan Kay
    DVA's advice. Jonathan
  25. Jonathan Kay
    :-) Congratulations. How did you crack it? Jonathan
