We’ve got it up and running! This wasn’t as smooth a process as we would have liked though: The first time the layout went up we discovered that the frog juicers weren’t behaving – they switched the current to the frogs but too slowly when the wheels went over and shorted. In retrospect they are designed for turnouts wired so that the switch rails moving will cause them to operate. As our switch rails are permanently aligned electrically with the adjacent track, this doesn’t happen.
Solution: Buy 39 Peco turnout accesory switches and rewire the turnouts. All peco turnouts done by Steve on Monday 8th, 7 tortoise motors also rewired by Richard on Tuesday morning. The frog juicers were abandonned under the layout for the time being. Eveything is now working.
Next problem – a MERG board overheated producing acrid smoke. Quick turn off and board replaced solved problem.
Last problem – Big Bear DCC wouldn’t talk to the Lenz system. We have temporarily resolved this by using an NCE PowerCab to control the turnouts and in the meanwhile, Pete of BigBear DCC is rewriting some of the code for us to ensure that Big Bear will work properly with Lenz – excellent support!
