M.T.H PS2 engine 30-1497-1E / Won't Move

what is the engine item number is it a ps2 3 volt or ps 2 5 volt, I believe it to be the latter! if ps 2 5-volt board might have issues! are you trying to run in DCS or conventual!

So this engine has the more reliable PS2 3V board. Do the sounds stay on and play a shutdown sequence when you turn off the power?

Yes, it does.

Conventional or Command operation? Does you transfer have an amperage readout?

Check the drive linkage to make sure nothing is jammed.  Re-seat the tether wire between the engine and tender.  Could be a bad motor FET on the board which will require servicing from a tech.

Are you running the engine in Conventional or DCS ?

If DCS. Does the engine come up silent ?  If they miss the watchdog signal. Sound, smoke and lights come on. If the track signal is good. It should respond to Start Up with the remote and run properly.

Do you have other engines that are working correctly ?

comes up with sound, lights, and smoke

Try a reset in conventional.  1 horn followed by 5 bells about 1/2 second apart.  Must get a confirmation two whistle blasts, if successful.  After that, test continuity of the tether.  Whit and yellow wires are the motor leads in the  loco and ten pin plug in tender.

Have done that twice and get the proper response but still nothing, checked the plug-in at the back of the engine to make sure the pins are straight. Everything would lead me to believe all is ok.

Withe the loco commanded to forward, wiggle the plug from the tender into the loco.  If the loco lurches forward, the solder connections on the 10 pin socket may be broken.  Otherwise, open it up and inspect the board & wiring, or find an ASC to test the board.

Look at the motor windings too.  Spin flywheel by hand. Motors burn up, solder joints break on the PCB as mentioned, but also on the motor terminal can fall off.  5 pin connector comes loose out of board.  G

Sorry for the delay in responding I've been ill.  I've reset, unlocked, checked the pins at the back of the engine, checked all the wiring, the tach strip on the fly wheel. I can't test the board as my PS 2 tester was destroyed in a recent move. So I am open for suggestions

Since you were using a PS 2 tester you clearly know your way around wiring and such.

I suggest probing the DC voltage on the 2 motor drive terminals at the 5-terminal connector on the relay end of the main board.  With needle-point meter probe tips you should be able to safely access the contacts even from the harness side as you can contact the metal crimp inserts with the probe tip.

Or even if your PS2 tester was destroyed, maybe you saved the cable to the 5-terminal motor connector that would be another way to measure the 2 motor drive voltage right at the PS2 board.

On power up the engine should be in neutral so no motor voltage.  Then since it sounds like you're working in conventional, the Direction button should cycle the engine thru Neutral-Fwd-Neutral-Rev.  And with track voltage of, say, 12V or so, the voltage should cycle from 0, some DC voltage, back to 0, some opposite polarity DC voltage.  And you should hear the relay "click" every other button press as it changes direction; BTW if you never hear the relay "click" at all, that's another issue.

If you never get any motor voltage, then perhaps the motor electronics blew a transistor.  But if the motor voltage cycles per above, then trace the voltage thru the connectors, harnesses, tether, etc. up to the 2 motor tabs.

How exactly do you "destroy" a PS/2 test box where it can't be repaired?

Did you inspect motor windings?  Is the motor bad?  If your sure everything else is ok, move the PS-2 board into another good engine, preferably steam and see if it drives the motors.  You need to start eliminating item through actual test.  G

Would you believe the ceiling of our garage collapsed and anything and everything in the attic came crashing down?

I guess with all that weight on it, for sure it won't move now!
