    Does anyone Recognise This 24 volt Alternator ?

    I'm re-working a large generator set with an 11 litre Dorman 6LE 6 pot diesel engine. The charging alternator is toast but I don't recognise it. No makers marks.

    It has a remote CAV 440A regulator so I suppose it's most likely a CAV one - engine is 1972 but alternator quite probably has been changed several times since then !

    I'd like to fit one with an integral regular to simplify and tidy the wiring.

    12 or 24 volt? ..... looks a lot like a Lucas 23 ACR as fitted to Rover SD1 cars which were very power hungry
    IIRC it was a 80A unit ..... but they had on board reg.s

    I slung out maybe 10 of 'em when I cleared my yard ... all known good units

    ON EDIT ..... just realised this is 24 volts .... from the title -- DER!!!

    If it's got tracks, wheels, t*ts, or an engine, at some point it's gonna give you trouble!!

    Problem solved!

    I gave up trying to remove the alternator the conventional way, and removed the adaptor bracket with the alternator still on it so I could explain the error of it's ways while on the bench using a bigger hammer.

    And guess what - an ID plate where it had been up against the engine. My local auto electric man had a working one on the shelf that had bad bearings, so I relieved him of it and Simply Bearings are providing the replacements in a day or so !
