Cool, thanks Marty. I will try and do it tonight and let you know.
As for your question Rod. Yeah it does register on the DMD. I might try and clean the switches a little, I thought the same thing, something sounds like it sticks.
Will also try and reset like Marty suggests.
Thanks again guys.
The whole unit unscrews easily (again with power off and unplugged). Its the earth which triggers the switch so look for anything obvious. Also check the earth to the coin door. Make sure its tight.
If this fails, refer to my last post re J205. This is a quick way to work out if it is plug/wire related or CPU board problem.
