Get a volt meter onto the trigger why for the solenoid, and then you can tell if the solenoid itself is sticking or if its a switching issue.
Thanks!... will give that a try
what you mean by switching issue ? sorry if i sound dull not too good with the electrical side :L
I mean like the ignition barrel staying in the "on" state for the starter circuit because the spring hasnt returned it properly when you release the key.
