Alton Solanoid

Hi, I have a norton Commando 850 that's fitted with an Alton electric starter. White removing the battery i touched the main frame with the small wire thats soldered onto the solanoid and now it wont start off the button.
The solanoid has two heavy leads and two small wires that's soldered onto the solanoid unit with a blob of solder. The small wire that goes to the positive battery terminal is the one that touched the frame. The other small wire goes to the starter button.
Does anyone know how to check the solanoid to see if its ok.
I've reminded it from the bike.
Thanks Neil Hall.

With the solenoid 2 heavy leads disconnected you apply -ve 12v to the solder joint where the wire come from the starter button and -ve 12v to the other soldered joint. There should be an audible click as the internal contacts close when the voltage is applied. Alternatively with the same wiring condition put a digital meter across the 2 heavy terminal's in resistance setting. As you apply the 12v to the 2 soldered joints the resistance should drop from infinity to virtually nothing.

Kommando you suggest (-ve 12 v) to both solder joints. I think one should be
+ve and the other should be -ve

Yes, autocorrect gone bad
