Cheers Gav, I will have good look and check the wiring against the manual. Probably every chance things may not have gone back where they should have at some stage.
Check your connectors especially the inter board connect ( try this loom on Hulk also)... look for any evidence that would suggest someone has removed then reconnected at least 2 wires...if its not a board problem.. it has to be a loom problem.. could be as simple as earth connect is in the wrong position
