If your coil is getting hot it's constantly being charged, because for instance your points are corroded shut. Or something else is wrong. I think the advice is to check your ignition.
On the up side: the battery seems to work.

Hi, cannot get picture to load?
Does anyone know how to remove all of the electronic ignition.
I wanted to see it had corrosion behind it.
Thanks Dave.

Sounds like the electronic box or sensor is fried if the coil is getitng hot as it is continuously passing current.
Could understand if it was points stuck closed.
I had an ETZ 301 and that had electronic ignition - the sennsor was easy enough to remove as if memory serves it was obvious which screws held the sensor in.
Good luck.

Just an update, put plug in and it did not spark but when put back in bike I kicked
The engine over a few times and nothing happened
But when I turned the ignition of it backfired
And a oily mixture splatted on back of my house.
Does anyone know what could be wrong
Thanks.

Take the spark plug out
Then turn the ignition on. if it sparks when the ignition is turned on, I think the black box is blown, likewise when turning the ignition off.
I have done this myself by mis-wiring the system before now.

Hi,thanks for all your help.
I did remove the generator cover and cleaned it out, it was a bit rusty, I think I need to strip the generator and get any corrosion of the parts.
I have some new brushes and the part the brushes fit into(sorry don't know the name)
I don't know were to connect a mutil tester to test things as I cannot find my Haynes manual!
