The duct can make a big difference my friend has a 3A, and following an engine rebuild it would always boil after a fairly fast run. we fitted the duct, & no more problems.

Hi Malcolm.
1st thought is do you have the "cardboard" ducting to direct air from the grill into the rad. without that overheating is common.
Also, when was the radiator last flushed through. they do get clogged up & so have reduced cooling effect.

Check your connections. in case you did not know (sorry if you did) the wiper motor has 12V from the ignition switch (via a fuse) on it permanantly, & the wiper switch supplies the earth connection. If a previous owner has wired the switch to provide 12V then that could be the reason you get lots of current, as the motor self park mechanism may be shorting it out.

Green is 12V from the ignition switch (via a fuse), so anything which only comes on when ignition is on will have a green wire going to it. The heater is one such item, so I am sure your diagnosis is correct.
But why was it disconnected??
Hi Miles. Your inbox appears to be full, I wished to send you a message regarding Shepton Mallet, & if you were going. Perhaps you could clear it, & send me a PM, so we can "talk"
Anybody else noticed that re-sizing photos no longer works - it seems to when composing the post , or editing it,
but when you save, the photo goes back to being full size ?
