Does anyone know where the best spot to look for a wiring schematic for a 3220 Plus. The worklights have decided they don't wont to work anymore and with all the wires being yellow and seemingly just doing loops around the tractor makes it very hard to trace. It is starting to do my head in, I have rang all the local dealers and as soon as I mention JCB everyone seems to be really busy!!!!!. Even the radio CD player wires are the same colour, I at least thought I could do that myself but no, need a bloody wiring diagram. Any help would be appreciated. Cheers.
