I did the honeywell 1 day course this week its very good.

If you have a fault you can test the motor and depends on the fault get a tester and see whats working or not as the case maybe.

Can you be specific about the problem you have or do you just want a wiring diagram?

Go to Honeywell UK Click on Download and download the Wiring Guide. It has all the fault finding info you need.

You will have to "register" to get any downloads from the Honeywell website, but you can put anything in as long as the email address is correct!

Taker the casing off the motor and components...Grab your multimeter and stick it to Ohms (resistance) and stick the two probes on the round thingy lol, like a coil of wires. I dont know an awful lot of electrics but that i beleive should tell you the motor is in good order. From there on its a matter of working back i beleive.
