Hello Nat, If you are referring to the direction change relays they are 240volt. I have a connection diagramme, showing the hard wiring, but no electronic info. You can get the diagramme from Yahoo groups/ Boxford users/files, or I can send you a copy if you let me have your email address.
Have taken an "educated" guess at the components to repair my board, and receive replacements today, so should know in the next couple of days if it fixes the problem.
I'm in Kidderminster.
Rgds
