Trying to sort out if it's me or the equipment. Engines in question Spirit of the Century F3 AA, #38153.

40" x 80" FasTrack oval with a 180w brick, Legacy PowerMaster & Legacy Controller.

Process:

  • Track off, both A units placed in Program Mode and set on track
  • Track powered up (Powered A has numberboards on, Non powered A has sound on and RPM's escalating, but no illumination)
  • Go through the ID process, Eng, #, SET. Powered A number boards flash, Non powered A does nothing and RPM's continue to escalate.

I have tried programming it with the PowerMaster set in both CONV/CMD, with no difference. Regardless of what I have tried I do not get the horn blow to confirm it has been programmed.

I popped the shell on the non powered unit and everything appears to be properly seated. I did find a 15 year old RAYOVAC that I removed. Battery did not show any signs of leaking or cause any damage.

I'm out of ideas, Anyone?? Thanks!

The fact that the dummy is reving immediately tells me that it does not detect the signal from the base.  However, your powered unit does responds properly so that tells me the base is fine.  Conditions that may cause the dummy not to detect the signal is antenna disconnected, antenna grounded, the radio board bad or bad connection. 

On the dummy inspect the wire to and from the antenna.  Disconnect the wire from the board and reconnect it.  Test.

If no change, then remove R2LC radio board and reinstall.  Test.

If no change, then swap the R2LCs between each unit.  Test.  See if the problem moves and the dummy now responds properly.  If so, then bad radio board.

I'll give it a shot in the AM and report back. Thanks!!

On the dummy inspect the wire to and from the antenna.  Disconnect the wire from the board and reconnect it.  Test. - No change.

If no change, then remove R2LC radio board and reinstall.  Test. - No change.

If no change, then swap the R2LCs between each unit.  Test.  See if the problem moves and the dummy now responds properly.  If so, then bad radio board. - Swapped R2LC's and it acted the same as when I started.

Lastly, I unplugged the PowerHouse and PowerMaster and ran it off the CW-80, again no change.

I'm stumped...

Jeff, I just pulled one of my SD-70ACes out last weekend and it would not program.  I found the PROG/RUN switch was bad.  It was easy to check with a VOM.   Try that.

The dummy is not completely dumb on this set.  It has the R2LC board to receive signals to control sound.  The non-powered unit provides all the sounds.  The radio board signals the sound board for horn, bell and rear coupler firing. 

The non-powered unit also has a Hall-effect sensor mounted to the rear truck.  I believe it detects speed so that it can change the engine RPM sound to match movement.   Maybe it went bad and sending a continuous false moving signal.  I suggest pulling the connector on the board and try to program again.  Here is pick of the wiring to the Hall effect sensor and where it is connected on the motherboard.

GRJ, I had swapping sound board recommendation all typed up ready to post until I discovered the powered unit does not have one.  Then I was going after a R2LC reset but the manual does not list that.   I planned on trying standard reset procedure if this AUX1-0 doesn’t do the trick.  
Sound board could be problem but he’ll have to find one from another engine to test.

You can swap the sound board with most any other RS4 sound board.  Might sound a little odd, but they're all electrically compatible.
