In DCS mode I have a engine with PS2 5v system that will stop abruptly when going over 2 switches (MTH), Looking at the rollers they are both in the dead spaces on the switches. I think this has been brought up before but I can not find it. Battery shows 8.9v. Please Help

Thanks Henry

Hello Henry, If you are thinking the battery will will keep the engine moving when the rollers hit a dead space, unfortunately it won't. The purpose of the battery is to keep the sound going primarily in conventional mode when the direction button is pressed or when the power to the track is shutoff and the engine can complete the shutdown sequence.

Best bet is to add additional rollers to the tender if it's a steam engine or change the arrangement of the switches to alleviate the dead spot.

for a test, put a regular 9 volt inside just to see if it makes it over the switches. Some batteries fail when under load. Take it back out right away.

On some steam, you can add a pick-up to the tender if there isn't one. On diesels, you can add the double rollers when they fit, if they aren't already there.

I've also seen where some wires aren't connected properly or failed, and the engine stalls like you're seeing.

I went back to layout and did some more testing and discovered that the sounds stop as well. earlier I had the sound off

I had two 072 in a row and i had to put a relay on one so it would energize the dead rails when the switch was  thrown in a certain way.  Ross has instructions on their web site on how to do this for the big switches.  It helped with my issue, not sure if it would help with your issue, not sure if the MTH switches are set up the same way.

Thanks Tony I will look at their web tomorrow

Henry, I'm not sold on the board being bad. How slow is the locomotive moving when going through this bad spot? If both rollers are moving through a dead spot slowly, you can expect the engine to shutdown. If you turn the engine around on the track and run it the other direction or just run it backwards through the same spot, does it shutdown?

I have another SD60 engine PS2 5 V that I tested as well.  Both engines were tested at 50 smph and in both directions one has no problems the other stops abruptly and sound stop as well. The layout has been down for 2 years now and I did not have any problems with the engine in question until yesterday. I have 2 areas where there is 2 spots that this happened. I still think its the something in the PS2 board. My layout is a large one about 50'x10' with 4 levels, 51 switches, 38 engines all DCS



Thanks Henry
