I have a pair of 3rd Rail E-7's and I'm running in conventional. I want the trailing E-7 to run in reverse as a default setting. If I move the RUN / PRG switch to PRG, while the trailing engine is moving backwards, the engine on each throttle cycle will stay locked in reverse. After I power down the engine, it then becomes locked in forward. This is true of all TMCC engines that after power is removed for more than about 5 seconds, the memory to stay in reverse is lost. I sent the engines back to 3rd Rail and one of Scott's techs reversed two wires at the E-unit and that must have worked for them at their location. However, when I got the two engines back, the problem of locking an engine in reverse as a default start, still wanted to defaulted back to forward.
Are there more than two wires involved in getting the TMCC engine to stay locked in reverse after moving the RUN / PRG switch to PRG, as the engine is moving backwards? (In TMCC I can create a lash-up, that will pair both engines, so that the trail engine runs in reverse as a "Train".) However, I'm operating in conventional and for now, I have to run both E-7's in "elephant" style. (both noses forward.)
What more is required to get the TMCC E-7's to start, with one in forward and the other in reverse as a default start up in conventional? Normally, when a TMCC, AA or ABA lash-up involves one engine to run in reverse, there's a connecting cord and plug between the lead engine and any other powered units so that the lead engine is the master E-unit.
Recommendations and information would be greatly appreciated to solve this problem as I need the pulling power of two E-7's and none of the 3rd Rail E-7's were offered as a non powered unit A unit and a powered B unit, that would have provided two pulling engines. Many railroads never ordered B units in the E-7 configuration.
Thanks, Mokemike
