Sorry about the delay, finally had time to dig the old girl out and do more checks - thanks to your lot I’m finally getting somewhere can’t thank you enough

I’ve tested the black wire with ignition on and I have 12v …. When. It’s connected to the regulator/ rectifier there is no 12v coming out of the white wire to the field coil (my understanding this should have the 12v the black supplies )

Forgot to mention mine had the new style regulator / rectifier all in one not the one you can adjust …
 Have attached picture (to show what it looks like offline ) 😇

I have no field coil activity by the looks with the ignition on the coil is not magnetised,  does anyone know what the resistance between the green and white wire to the coil should be or any other tests I should do before swapping out the field coil
Thanks

Have got the side cover completely off and added 12v down the white and earth down the green and my coil is working fine,
I’ve checked white wire out of the regulator and no 12v is being sent to the coil hence no charging  (I’m guessing )
By reading up…. I’m sure the black wire to the regulator is the 12v ign feed and also shows the regulator the charging status …. So next test would be to see if I have any voltage on the black wire with the ignition on… thinking this is correct 👍

Thanks everyone for the info / replies
Will try and get my head around diagrams etc that have been attached, I’ve also checked all the plugs on the charging system and all in good condition not corroded.
I will check the magnetised idea on side cover later ….

Thanks for baring with me I’m not the best on electrics or even using the internet forum.


Much appreciated 👍👍👍
