About this deal
My ignition light is on at rest and with the engine idling, so maybe I can assume the cut out is currently working?, before I replace the dynamo. Make sure its machine sensed. i.e. the two B+ terminals are shorted internally or externally together. The alternator to battery feed cable will work but a parallel cable will allow more loads to be added without visible volt drops. If you connect the dynamo to a battery just with bits of cable it should run like a starter motor but very slowly.... If it runs? it's ok if not? it is kapput. Hi. Have fitted the recon dynamo. The voltage, direct from dynamo, is reading similar to the old one. Thanks for that info guys. Just wanted to be certain I couldn't be doing anything wrong, as the tests on old and new unit gave the same readings.
The field coil resistance is 6.3, measured with dynamo fitted. Is this a tad too high to make much difference?.Hi. I have hopefully diagnosed this as the dynamo, as with a connecting wire between the 2 dynamo terminals give rapidly fluctuating readings of between 4 and 6 volts.
