  i have picked up two mth engines in the past 6 months.   Always been a Lionel guy but I was ready to branch out.  I picked a new old stock unshrouded J new in the shipper.  This is one of my all time favorite engines.  Normally I don't buy much older stuff I try to stick to the more modern offerings.   However I love the engine and couldn't beat the price.   I did some reading before I ever unboxed it and I read about the battery issues and board failures of the older ps2 engines so I prepared myself for the worst just in case.   I took the engine apart cleaned out all the factory grease and replaced with fresh.  Also oiled everything before  I ever turned a wheel.  That's a lot of years to live in a box.   I put the engine on our club layout, started it up and it worked great for 2 passes around our roughly 20x40 layout and it just died.  Quit responding no function dead in the water.   I moved the engine  off the main to the yard and just left it sit on a powered yard track while I chatted with the other members.  I decided  before I left I'd give it another try.  Engine started up again.   Ran fine again for about 20 feet,  sounds cut out,  made about half a loop on a main and same thing. Dead.     Member suggest changing the old battery out for a bcr.   I have since done this with mixed results.   The engine is very difficult to start up.   When 18vs is applied the whistle blows constantly with no other function or response from the remote until power is removed.   I tried throttling the power up slowly instead of just switching on the full 18v and this does seem to work but it's real intermittent.   Sometimes the engine will respond sometimes it won't it's very inconsistent.   But when the system does start up the engine seems to preform perfectly it's just getting it to start.   And as soon as power is removed say via short you have to start all over again.   I love this engine like I said and I'd really like to find a fix for it.    

Secondly I picked up a used PS3 c&o greenbrier.  These had been out for about a year  when I acquired this one.   Engine was used.  Love this one two very attractive loco.   This engine right out of the box had some issues.   It would start up and run however the operation was very jerky.  It will speed up and slow down with no speed step changes.   Sometimes it will just stop and the sound system will shut down like power is removed.  It will sit for a few seconds and start back up on its own.  Only thing I could think of to check was the wonky draw bar.  Which is tricky but seems to be properly and firmly connected.  I did take the shell off and check for any mechanical issues like I said it just ran very poorly when it did run like it had a driveline issues.   I found everything to be in good order best I could tell.  I assumed it was electrical but it was worth a look.  I  Reassembled the locomotive same results.   Sometimes it works sometimes it doesn't but when it does it just acts very unhappy about the fact that it is working if that makes sense.  I had it running on our club layout with about 20 cars in tow and it would slow down to crawl and stop.   Sound system would shut down and it would sit for about 30 seconds and come right back to life like there was never an issue.   I did try it in conventional at my home and it seemed to work fine mechanically other than it wouldn't let me toggle it from any other position than forward .   No nuetral and no reverse.    But it seems to run better in comvnetional than full DCS.   It's over my head I know that.

We have have a local repair guy here but I thought about sending the greenbrier back to mth.  I love the engine but I really want it to be right.    Obviously both engines need some kind of repair.  Whether I use the local guy or mth.  I for sure want to get these up and running. Two great engines that I was pleased to add to my roster.   I'm not really upset with mth.   Stuff happens that's part of it but it's deafinetley been a less than favorable beginning.   The J I kind of expected because of the age but the greenbrier I had much higher hopes for.     

 Thoughts and suggestions welcome.   

How is mth customer service?

Everyone will be guessing on this. It might help to have model numbers for the engines and also the model and specs of the BCR you installed. BCRs and PS3 engines need a full 30 seconds to charge, then you start the engine startup sequence. It sounds like you are running these conventional. For the PS2 engine, it might need a reset if you had a bad or low charged battery in it. Very old PS2 engines should be charged for an hour before running them. Then, there is a process for checking whether the battery is good. This is documented on the MTH site. It's hard to fully troubleshoot these engine without a DCS system too.

Just a thought, sometimes certain engines can be pickier than others for a number of reasons.

Just for kicks, try connecting your 2 outside rails together if they aren't already. You can just use a temporary test wire with alligator clips for example.

I'd be tempted to say the first has a tether issue also but I'd have to have my hands on it to tell. You could retouch the solder pads inside the engine if you are careful and keep them for shorting together. Some boards don't like BCRs and I never can figure out why. I think they are picky about powering up. You might try a new MTH battery.

 Intermittent  electrical issues can be a challenge. You have to search methodically to rule stuff out.

Good point. I recall something about certain two-rail capable engines only getting common from one set of wheels.

Be very careful with tethers in the tender. A pinched wire can doom your PS2 board. I know from experience.

The unshrouded J has the older 5V board which is obsolete.  Since you changed the battery did you look at the speaker?  I bet it has deteriorated around magnet.  Common with that specific vintage speaker.  But the bigger issue is the 5V board becoming erratic.  That can happen.  This engine can be repaired by replacing with the PS-32 board, new speaker and eliminating battery.

The C&O can be a multitude of things depending on 2R/3R and other factors.  First make sure wheels clean, pickups also (and lubricated).  The drawbar can be suspect especially if a pin has a cracked solder joint.  Also can be communication between tender and engine with a wire that has broke in the harness that plugs into the engine.

Just needs to be gone through by a good tech that understands PS-3 engines.  G

sorry you are having issues with the greenbrier, I have come to find out that with that many cars on it you can put stress on the drawbar and it will disconnect I use a rubber washer on the tender pin to keep the drawbar from disconnecting for the plug, I have run that unit without any issues it was one of my best Locos, try to run the loco with dcs without any cars and see what happens

fl9turbo2   no worries man we'll get it straightened out.

GGG on the J I will check around that speaker for deterioration.   I feared that board from the beginning but I wouldn't mind going full ps3 upgrade on this one.  One the greenbrier I will give the rollers and wheels a good cleaning and check out those solder connections.

.  I will try to clip the rails together and give it a try.  I will also inspect those tether connections closely.  I will also try putting in a mth battery. 

, ChiTown Steve   It could very well be they layout power and or electrical however we run many other dcs engines without issue.   Ranging from early proto 2 to the most recent releases.

Thank you all for your feedback its much appreciated.

Not to dash your hopes of branding out, but I too have been a Lionel man and run conventional only.  I tried a few MTH locos over the past three years and wound up selling every one of them.  Not so much because they had major issues, but because running them required too much preparation in the way of programming.  Basically, too much electronics for me.  

If you got a really good deal on any brand of engine, you'd probably expect something's wrong with it. I have got ones that ran fine. Maybe some small blemish or something else that never bothered me. I don't wish to take jabs at any brand. That would be in poor taste right here.

Buying rough engines second hand, let alone this old, can be made fun if you learn how to fix them. Putting a new board into them can make a solid investment with up to date features. I have learned to repair and troubleshoot that helps me with other issues as well.

Sometimes when the work is over my head, I bite the bullet and send it to a pro. It's nice to have someone else do the work and stand behind it.

I have three of the unshrouded J's. Why do I have three? I couldn't afford to buy six. I had to replace the board in one of them. Still one of my all time favorite locomotives.

As far as your Greenbrier goes, look at replacing your drawbar. The symptoms could be caused by a bad drawbar or a plug that isn't fully connecting.
