Hi, I am new to the hobby and have just bought a c7042 digital 6 car power base along with some track ,including 2 lane changing corners. Without using the Lane changers the track works perfect in digital mode but if I connect the Lane changers the 6 car power base goes straight into SAFE mode. Even if I just have the power base on its own with the Lane changers only connected it still goes straight to SAFE mode. I have actually spoken to someone at scalextric who advised me to read the instructions! I have done this but I'm at a loss. Can someone please help?
