Digitrax AR1 Installation

Installation of an auto-reversing unit on a wye. The AR1 unit by Digitrax automatic alters the polarity of the rails before the circuit breaker on the command center realizes there's a fault. Easy installation, simple wiring - but remember ALL feeders from the bus line must be run through the AR1 unit or the unit won't work. Also, both legs of the wye must be isolated on both rails and if you're using Kato or any other power -routing turnouts, make sure the power -routing option and powered frog is turned off - you can do this with the screws on the underside of the #4 turnouts.
