Mike, Got it, but correction. When using the stacker board to repair a PS-2 5V or 3V you do not need a PS-3 Slave board. That won't work. The Stacker can drive the PS-2 slave fine. No changes required.
PS-3 diesel to PS-3 Slave is different and sends data to the PS-3 slave to operate all features in the slave. PS-3 slave also has a tach motor, which PS-2s do not.
Bottom line is a stacker can repair any PS-2 engine that uses a slave board including some of the turbines that had both boards in a 4 motor A unit. G
