Hi all

I'll take a pic of the tool height setter tomorrow and check those other suggestions, but wondered if I touched the two plug terminals of the THS with a circuit tester and apply pressure to the pad would that make or break the circuit and tell me if it works or not??

As for your suggestion Andy, I got the impression when it first blew a fuse the guy that runs, owns the company only has limited knowledge and employs an electrician to do the wiring, but you can never speak to him, it's always relay the info through the boss bloke, where it would be much easier to just speak to the electrical guy and explain it direct and get a direct answer back.
