okay, so today i decided to investiagate my charging problems... having replaced the dial lights (most of which were blown) i couldnt get the battery light to go off, i tested the relay and that was fine, so i refered to my Jawa manual for some other checks and found my regulator to have burnt out one of its contacts (melted the solder on one of the spades) but even with that repaired i cannot get a charge.
i then moved on to the regulator unit which should have a field current of around 2amps being fed to it from the alternator at terminal "DF", but that was stone dead. i tried switching in the ammeter straight off the alternator brushes but am still getting nothing off it.
im pretty sure its my alternator, possibly the windings but am not sure if/how i can test them, ive just added new brushes and the alternator was partly dismantled when i got it, there seem to be two small blocks mounted on opposite sides of the alternator with a small off-centre plate rotating between them (the movement of this plate corresponds to the diodes flashing on my bridge rectifier) these blocks are adjustable and i did not have a referance when re-assembling the alternator, maybe this has something to do with it?
is there a way to manually excite the alternator using another battery to see if i can then get it to charge?
any ideas appreciated

(Battery was charged for testing, should have been enough to excite the alternator?)
