Update:
Got a PM from Guard telling me that there is issues with the CPU. He took it to Dave in Collingwood who was unable to repair it. He says he's now going to take to some guy in Muskoka. I had a feeling that this was what was going on. I hope Guard is able to locate a new board for a decent price. I know how hard they are to find as Rottendog has stopped making them. I also hope that there is not an intermittent short in the wiring harness that I believe caused the initial problem with the lamp driver. It's a good lesson for all our Revolution brothers. As for me, from now on I'll stick to my EMs. At least I know I can fix them.
