PS-1 stuck in Reset

If the only changes that you have made since it last ran is to add the BCR, have you given the BCR a full minute to charge?  If the BCR isn't fully charged, the PS-1 board will not respond and operate normally.

Thanks for the reply but that's not it.  The BCR is good and previously so was the battery.

Try pressing the boards together at the connectors.  Sounds like you may have a bad connection.

Been a long time since I have owned a PS1, but isn't that the Clangs of Death?

I have a PS1 repair chip you could use if that is the problem.

Nope. This is something different. Just stuck in reset mode. 

Please take some video of it and show your hand on the Z-500 in the same frame so I can see exactly what you are doing and I can tell you exactly what is going on..... I am not sure if I am totally following what you wrote. It's easier to see it as if I am there myself.

Video shows using the power control and then the direction button.  The recording has a tapping sound that I can't hear live even with my ear next to the locomotive.

Hello Ron,

I have a couple of PS1 engines that run just fine. 

But what is a PS1 repair chip? 

Is this something I should have in my tool box for future use?

im not sure why you’re starving it at the very first notch on the Z-controller like that... PS1 needs at least 8v to start up properly and should be brought all the way up to about 16v briefly on power up. I wait until the start up sound finishes, then throttle back down from 16v to about 8v (a little after 12 o clock on a Z-Controller). As you roll back toward 8v you’ll  hear an engine let off sound like this “shhhwaaaaaaaaashhh” (and if you repeat that cycle over and over you’ll be scrolling through resets). But with every start up I bring it up quickly to at least 8v and then up to 16v and then back down to about 8v. Then I hit DIR or throttle off and up again within a second and it unlocks.

keeping the throttle where you have it around 9-10 o clock is about 3-5v. That’s STARVING her and probably not allowing that old early generation PS1 board to unlock properly.

Gen 1 PS1: 1993-1994 doesn’t care what power you use or how you cycle

Gen 2 PS1: 1995 normally needs pure power to unlock from reset, period. (Z-4000, or postwar power)

Gen 3 PS1: 1996-1997 (deselect era) will work properly on the Z-controller or TIU chopped wave, starting at at least 8v

Gen 4 (final) PS1: 1997-2000 will work properly on the Z-controller or TIU chopped wave, starting at at least 8v

*OP - try turning your throttle up to 3 o clock on start up - wait till engine start up sounds play out and then roll it back down to off and back up again, or roll it down to 12 o clock and hit DIR. see what happens.

Allegheny, 

PS-1 Reset Kit is 50-1023 and pictured here.  I guess the main culprit to the Clangs of Death is a bad battery.  You pull OUT the PS chip with the chip puller.  Replace the battery and INSERT the reset chip, follow the instructions.  Then you replace the original PS chip.

An interesting note side note...  Since it is believed the OP's problem is the engine is stuck in reset, here is the last step in the in the instructions...

11.) If the engine still will not leave RESET contact MTH Service. If you have any questions during the use of the Force chip, contact a MTH Service Technician, 410-381-2580.

My understanding for power up was to stay below 10v to come out of Reset.  I followed Ddot's guidance but got the same result.  When I try to move, I hear 1 bell, the engine sound fades out while the pumping sound continues.  Throttling from 16V to 10v I hear the shush and 1 Clank.  At no time are there 3 clanks.

When I had the issue before the shop in Hagerstown said there was nothing wrong and that it ran fine for him.  I got it home, paid closer to attention to moving the throttle and after a few attempts it ran.  I assumed it was overly sensitive to voltage and ran it some more times before boxing it up until this week.

I assume the Force chip is worth a try.

if you have the chip try it - if that doesn’t work my bet is a loose board connection or cold solder on one of the boards ..I think someone else mentioned that before.

you're welcomed to get in touch over email if you need help/repair 

The ONLY thing the reset chip fixes is the three clangs of death.  It will not fix this problem.

You need to turn up the throttle up to at least 12v for the first minute of start up. The bcr needs it and the ps1 board needs it for start up. After that, drop the throttle down until you hear that  schwish sound as stated above. Then hit the direction button. It should go. I have more than one ps1 engine that will act just like that if not started like this. Hope it helps.

Gunrunner, BTW I did try seating the boards together and checked plug connections.

Paul, I've tried that and any combination I can think of repeatedly.  The "schwish" only sounds when I throttle up above 16V but is always followed by 1 Clank.

Are there any recommended repair guys within an hour or so of Gettysburg?

Do you have a MTH Z4000 or Lionel Post war transformer you can try the engine with? 1033 or larger.

No, I only have that transformer.  As you are the second to suggest (my words) that an MTH transformer is not good enough for an MTH engine, I have started looking for Z-1000.  I'll consider a 4000 if I come across a very good price.

here’s what you have to understand. That is really a QSI engine inside an MTH body. The engine predates that controller so the appropriate compatible transformer is one from its day - the z-4000 or sometime older like postwar. yes, I realize that is not the answer you want to hear - but truthfully - MTH engines (electronically speaking) didn’t really begin until about 2001 - with PS2. Those engines through today will have no trouble with your MTH controller

I think the Z-1k is also a chopped wave fyi. Pure sine is more important than a mfg. label matching up on PS1 I recall my brother saying that about his, and my buying a KW for him that he used for a while.  He was mad as a hatter too. His early mth experience wasn't all that great, but he still prefers it.

I, on the other hand, am amazed at how many "down engines" he put up with and still loved it. 

I liked that PS-1 history breakdown @DdotCdot . I don't think Ive seen that before.   It helped me put brothers MTH issues into better perspective overall.  It was the #2 PS-1s that held all the issues for him from what I can tell.
