PS3 Steam loco needs help - electrical, board? GGG, GRJ?

Are you only working on fixed one or two channels from the TIU?  We have found that while we set variable 1 and 2 to fixed, it often reverts back to variable and the track gets no power, hence no signal not interaction between remote and engine.

Probably time to have someone look at the wiring and make sure nothing is shorted to the frame.  My first step would be to test the boards on my PS/3 tester and then examine the wiring.  The random operation suggests either a wiring short to the frame or a board issue.

Are the tracks and running gear/power pickups clean?

We had 3 of our power blocks reverting yesterday and none of our PS2 or PS3 engines responded until we reset the variable to fixed. They would respond to Z4000 buttons for direction but only to hesitate before resuming forward motion.

None of the engines could be found by the remote on read or add an engine.

Other engines all read fine, Ron, so unfortunately, I’m leaning to a board. John,  I’ll check for loose wires, then if need be send her out. Thanks for the input.

Jim,

Some you win, some you lose. I hope it is just a loose wire or short easily recognized.

what kind of voltage and current draw are you experiencing when you have these issues ! p.s you might have created a short while you were working on the gearing issue or pinched a wire!

when you repaired the slipped gear if you disturbed the ac wires and put them on top the the ps 3 board that will kill your dcs signal you CAN'T HAVE THE AC Black AND RED WIRES ON TOP OF THE TOROID COIL THATS WHERE THE DCS SIGNAL IS LOCATED!!!! and the capacitors must be folded over flat on the top of the board
