Jerky Operation with EZ Command Plus

[Erik]

I am not new to the hobby, but I am new to DCC. I recently built my first layout in my house (I previously ran on my dad's DC layout). My layout uses exclusively EZ Track, primarily the silver roadbed with some black mixed in, with EZ Command Plus. I successfully assigned channels to turnouts and a DCC locomotive (Athearn). However, when I turn the throttle to run that locomotive, I have to continuously turn the throttle--most of the time; occasionally, it will run for a few seconds without constant turning of the throttle.

I am fairly certain this is not a bad EZ Command box because I actually returned the first one I got as defective based on this issue. This issue also arises on my secondary test/programming track, so I thought it was the box. However, my newest one also has the same issue, so I doubt I received two EZ Command boxes with identical defects. Any ideas what my problem could be?

A video of the problem:

If I need more power...then I'll need help because I bought a 5-amp booster, but I cannot decipher how to actually connect the booster to the tracks. Some threads indicate that I should be able to splice the wires that came with the booster to an EZ Track clip, but I have no idea how to do that, and I couldn't find a thread explaining how to actually do it.

That's a lot of track on that layout. How many power feeders are you using?  Even with a 5 amp booster, just one is not enough for that much track.

...just that one power pack with the intention of "upgrading" it to 5-amp once I figure out how to connect the 5-amp to the tracks.

After reviewing your video, it looks like rotating that knob so rapidly is producing intermittent connection to variable resistor for that knob.  Understand that that knob on the EZ Command Plus (44933) is called an infinity knob.  That is, you can turn it (like shown in the video) without hitting a stop.  By turning it rapidly disconnects occur.  The green indicator to the right of the knob shows the value of the voltage going to the track.  That green indicator should steadily increase power to the track.  The video shows that the green indicator is only increasing by 1 or 2 then reducing back to 1.

Since the EZ command plus power knob is (pardon my expression) "sensitive", move the knob slowly and watch how the green power indicator reacts.  Slow movement of the knob should reduce the intermittent loss of connection, thereby allowing the power to the tracks to increase.

Check out the Bachmann video to see how that green indicator should operate.

The video isn't one of Bachmann's better ones, but it shows how moving the knob rapidly produces that what you are finding.  The next portion shows how the green indicator should be increasing with each slow rotation of the knob.

AS for the amount of track in the video, the Booster is (in my opinion) overkill.  With one locomotive it should operate quite well, with the exception of loose track connections, dirty tracks, or dirty loco wheels.


Hope this helps.
