    'powdering' of alternator belts...

    I know, you thought I'd ****ed off...no such luck. Settle in. Long bumpy ride awaits... I *did* think I'd got it sorted. I went back to the 15-year-old alternator, after doing a sort of ghetto-bench-test, since I didn't really trust the shop that said "the diodes are failing" - they are, I...

    'powdering' of alternator belts...

    I had a look at the two old rectifier boards in my spares, both presumably in need of replacement. And yep, those diodes are swaged in or some such - not a simple solder-replacement at all. And of course, they all test fine anyway, but...I musta taken them out of service for SOME reason...

    'powdering' of alternator belts...

    Mykey - thanks for all the pointers. I just tried the hand-spin test - no resistance felt (key on & connector in place, right?) The other test (bypassing existing leads) seems unnecessary to me, though I'd do it anyway if I had a quick-disconnect female terminal of that large (1/2" or so...

    'powdering' of alternator belts...

    Interesting...gonna try the hand-spin test ASAP. But as to that small-terminal connection: truly, this is not required for the alternator to charge? I thought that kind of alt function was possible - but only in alternators called something like "one-lead" or similar. (I think I once rebuilt...

    'powdering' of alternator belts...

    Actually that would be JUST like my vendor to supply such an item and not know it themselves - but I'm thinking that minis left the realm of "positive-earth" when they made the leap to alternators from dynamos in the late sixties. The online parts catalog doesn't show any options for alternator...

    'powdering' of alternator belts...

    Good observation; you're right about the original +earth setup, but this one is far from original...in fact, it's a fiberglass body that's identical (well, mostly) to the original, so my battery leads (both) run all the way from the boot to the front, where I had to ensure that everything got a...

    'powdering' of alternator belts...

    Thanks all, belt isn't sitting at bottom of the pulleys, though with all the powder being generated, you'd think it quite possibly so. Question: when I set this up in 2000 with the now-dead alternator, I retrofitted an LED/resistor in lieu of the basic charge-light, since I don't have a...

    Yes, but that was in about...1982...? Been running on a Lucas rebuilt alt for many years since then - only recently replaced due to still-present problem. --Dave

    'powdering' of alternator belts...

    Thanks, guys...I'm going to go flog away at this some more later today... (jon small): I was thinking along the same lines about grounding/earthing, but I get less than an ohm resistance from alt case to ground strap (to the stranded copper itself, which runs directly to the battery in the...

    'powdering' of alternator belts...

    I thought my old alternator was toast (after all, it was 15 years old), but a brand new one is doing exactly the same thing: the belt is snug (and only a month old), but my system is barely charging, or not charging at all, but the belt is squealing and heating up the pulley at moderate RPM, as...
