MTH premier SD45 ps1 issue

I read alot of posts about this issue and followed all of the prior solutions to no avail. I am assuming I need a new chip And or the bottom board is bad? am I correct on this?

 

What voltage are you using???  Presuming your battery is Good, "Proto-Sound" will NOT shift out of "Initial Reset" above 10v.  These engines start up in  "initial reset" NOT neutral.

I will bring my multi meter home from work and give you an accurate reading.

As stated above, you need to start up with about 8 volts for a minute or so, then it should cycle to forward. I had the same issue, thinking I needed a high voltage to charge the battery first. It turned out as long as the battery was charged already, all I needed to do was keep it under 10 volts to get it started. Good luck!

I have tried that as well. I think that since the neg wire from the battery came loose from the board it is a bigger issue.

I also have no bell or horn sound.

You may need a post war Lionel transformer with a pure sine  wave. However the loose battery wire is not good, Maybe  someone can post a pic of were it goes, It'll be close to the red battery connection.     Some of my early ps-1s would run without a battery. Not sure about this one though.

You will not have access to bell and/or horn/whistle until y the engine is out of "initial reset."

 

And as broached what power supply are you using?

I have 2 polarized CW-80s

I missed that in your original post.  Now, many MTH engines do NOT like the CW-80.  In fact if you look at any MTH owners/instruction manuals the Lionel CW-80 is NOT listed as an acceptable power supply for their engines.

 

Have you run this engine before with these CW-80's?

 

I had a MT-2100LP (20-2100-1) that would ONLY run with a pure sine wave power supply (in my case a KW).  It would not run with any "modern" power supply until I had upgraded by QSI back then.

Yes I have run ps-1 with these. It is a loco on the "list" aswell. Dash 8

When it comes to resetting Proto 1 locomotives, I've only been able to do it with an MTH Z750 or Z1000.  I was never able to reset them using a CW-80.

In my experience, early Protosounds locos will only come out of reset and run if powered by a Z4000 or a postwar loco. CW80's and Z750 or 1000's don't work with early Protosounds locos. 

I use CW-80s for all my 9 PS-1 locomotives that range from the 1st version to the last version of PS-1.  I also think you may have the voltage too high to leave reset.  Make sure you do not turn the voltage above 7 volts before you push the direction button.

crofinger,

 

Well, the "FIRST" most important thing is to fix the battery wire and make sure the battery is charged up. The engine will never leave reset without the battery making connection with the PS1 board!!!

 

 

What "list"?  A power supply list?
