    An electrical schematic is no problem. I’ll send you one. Big question is do you know how to pull Diagnostic Codes and if so what results did they throw up.? A misbehaving motor speed sensor would probably be top of the probability list.

    Thanks for your efforts Nige, no I’m unsure how to get codes, a colleague has been to look and tried with ET but no go apparently Is there a procedure ?

    There ought to be an old school way of getting Codes. Not having ben around one of these grey market machines I first have a question. Does the area around the fuse box and the diagnostic connector #3 look like the photo below.? Specifically does the machine have the Harness Code plug #2 and the indicator light #4 as depicted.?

    Figured it out, the main power relay/ solenoid was faulty, only had 7 volts getting to the fuse box. Easy one for a change.
