Help! Can anyone tell me how to wire an alternator?
I converted back to a dynamo 2 years ago, and I need more power for the winter, I’m forever watching the ammeter when the lights are on - the charging system just isn’t man enough with electronic ignition and a decent headlight bulb.
I have a 30 Amp alternator from a Case tractor and a regulator that I fitted many moons ago and gave good service, I only went back to dynamo because it didn’t look right.
Now try as I may I can’t remember with any certainty where the wires go, and there’s only 2 on the alternator and 3 on the regulator!!!!!
The alternator has “+” and “Ex”
The regulator has “D+” “D-“ and “DF”
I’m guessing alternator body earthed (-ve) and “+” goes to battery via ammeter.
Now something tells me the “Ex” is for excitation to make the alternator charge and needs a feed from the regulator …”DF” perchance ?? And I think D+ and D- are connected to the battery to read the voltage and switch DF on and off as necessary.
Please be kind with your answers, I’m not as young as I used to be. I knew how to do it once, and the really sad thing is, I drew a wiring diagram, but I don’t know where I put it!!

ps Where does the ignition light attach?
