Hi Guys, I you all can tell  me what is probably wrong and I might not like it but I have to know!

Today I was running my MTH ES44AC PS3 when I messed up and had to back it into a switch, here is the deal both lines are on the same side of the Z4000, one set of trucks went on one line and the other went the other direction in the switch on the other line. Never seen short warning. But still killed the power.

Now it wont do anything and the signal test says out of range. Please can someone help?

I tested all my other engines on #1 siding, I also call it my test track and they all get 10's

Ok Joe, so do I have to switch my track power fixed?

??

I don't know how you're wired here. You either run jumpers to a spare piece of track from a transformer, or shut off the DCS signal to the rails.

You may have the ability to shut off the signal if you're wired to say fixed #2 on a loop. Killing the power to fixed #1 and the aux in power, would do it.

I have a spare Z1000 on my bench that I wire direct to an engine when needed for a test.

Using your Z4000 handle you'd power up directly and then do the reset if it starts.

you may have damaged the engine electrically from the breaker trip ps3 and ps 2 engine boards do NOT LIKE SHORTS the shorts send high voltage transients that can damage the tiu and engine boards easily! you might have an mth asc test your engine! Sometimes you can do a conventional reset with z4000 that may or may not correct the problem but it's something t try!

Hey @mike g. I have had a similar problem with my MTH engines where they short and then stop responding to my remote system. Here is what I have done in the past that has worked. Not sure if it will work for you. 1 - Remove engine from track. 2 - Delete engine from DCS remote 3- Place engine back on track (with no other MTH or Lionel engines on track) 4 - Add engine back into remote. If adding the engine to the DCS remote is successful, you should be back up and running. If not, I have to agree with the folks here that something may have been damaged when the engine shorted out. Also note - if you already factory reset the engine than you have likely performed my steps as the Factory Reset deletes the engine from the remote.

Thanks Chris, I will give it a shot! Right now it seams as if I have nothing to lose! I will have to hook things back up to my TIU. But I would have to anyways!

Thanks and Merry Christmas!

Just talked to a service Tech, and he stated that because I split a switch with one end of the engine on one track and the other on a different  track that maybe I might have pulled a wire lose from one or both of the trucks. There were no shorts and none of my in line breakers popped so tomorrow I plan on taking the shell off and having a look! Wish me luck! LOL

I hope it is a wire pulled off, Mike!  If not, I think you are going to have to ship it out.  I had to ship one out before, the guy here in Pennsylvania (not a Forum member to my knowledge) had a fast turnaround, once he got the parts he needed from MTH.  That is the issue if you service technician doesn't have them on hand.  I know guys like GunrunnerJohn and GGG George keep parts on hand, but you can't have everything on hand.

Mike, you can remove the PS-3 board and send to a tech to test.  There are some faults repairable on the PS-3 diesel board.  There are no clinks and clanks on PS-2 or 3.  No hi current draw indicates the board is non responsive and doesn't have a major fault.

No sure how the tech thinks you pulled wires out because the truck turned different way  G

Hi George, is there any thing I can check before sending the board out? I checked and I am getting power from the rail to the screw that holds the wires on top of the truck?

If not can you give me an idea what the cost could be and send me an email with your address?IMG_20201222_062012479IMG_20201222_062020802

What happened is I was backing the train up in the photo below and the back truck stayed to the right and the front truck went on to the track to the left. No short indicators went off and none of my inline breakers popped.

Any help would be great!

For Mike and others reading, I would suggest putting at least a fuse inline after the Z4000 for events like this. You can't possibly react anywhere as fast as needed. It may or may not have saved this engine? It wouldn't hurt! It would save equipment that bridges the rails in derail events.

I just have an auto blade type fuse before every TIU channel on mine. Cheap insurance that will pop before you can think that fast. The Lionel 180w bricks will also pop even before the fuse does. The Z4000 that I have, doesn't react as fast.

The breakers on the Z-4000 handles are 12 amp . I use the remote receiver than plugs into the side of the Z-4000 and it shuts down the voltage between 9 and 10 volts by just dropping down the volts to zero. One little spark and it drops out the voltage. You can bring the power back up using the remote. I used this system before DCS came out and it ran my PS1 and Post War trains GREAT!

P.S. Mike,

The feature 18 with the Clinks and Clanks reset is for PS1.  I was going to suggest a recover engine, but if it doesn't work in conventional, don't take the trouble.

Hi Joe, I have the remote receiver also. Maybe I am just don't have it set up right.
