HI there
Thank you for all the input. I think i will hold onto the controller and get it tested on a BT truck first. I am not sure the nature of the fault except the customer has identified the traction controller to be faulty 'intermittently'. I have stripped the unit down and tested it at component level and cannot really find anything which is unusual. Not sure exact nature of the fault, we are still waiting to find out further details.
