Thanks Tony.  I was afraid that was the answer.  I will change to TCS or Soundtrax.

I want to change the mid-range and top speed of the model.  It has the generic decoder common with the locos that are DCC Onboard.  Usually the two CV's related to those two characteristics are CV5 and CV6.  Literature with the loco did not cover the CV's in the decoder.  Searching the Backmann website, so info for the generic decoder was found, but it did not contain any information about CV5 or CV6.  I get the idea that these two characteristics may not be changed in the decoder.  Is that true?  Does anyone know if these two CV's control the mid-range and top speeds, or can they be controlled in another location in the decoder?

Inspector,
It is my understanding he is using a Bachmann Dynamis system, which has one handset (throttle). Not a Digitrax system with two or more throttles.

But the problem is not in the decoder.  The system is creating a throttle setting that makes the loco move when it should remain still.

Your problem exists because you have more than one throttle addressed to this loco.  The other throttle has a speed setting other than zero.  You need to find that other throttle and dispatch the address, then move to your current throttle, dispatch the address, then re-aquite it.  Good luck.

klunker, I suggest looking at page 6 of this list of topics in N gauge.  There is a discussion about installing a TCS Z2 decoder in this loco.  It is a hardwire type installation.  Good luck.

That shows the correct wiring of the H16-44

The pins are as follows as you move in from the end.  .......

Thanks to all that have posted.  I performed the installation on the loco last week, before all this information came along.  Here is my report:

I used a Z2 decoder from TCS.  It is a little smaller than the Digitrax DZ125 and the TCS M1.  It also has 1 amp motor control, so it is robust enough to operate a N Scale locomotive even though it was designed for Z scale applications.

I located the decoder in the well underneathe the cab.  There is ample room for the decoder with some tape to hold it in place.  That means I did not have to remove the weight.

I checked with the NMRA standards to identify the location of the numbered positions on their 8 pin plug design.  Then I matched that up with the numbered solder tab locations on the light board.  I tested the loco with DCC once all the attachments were made and it ran perfectly including all the light contols.  I then replaced the shell and began setting up the decoder to operate on the main line. 

The loco runs very well when attached to a line of rolling stock.  It jerks at low speed when operating without the rollings stock in place.  My customer is very happy.  It is doing much better than his Kato/Atlas H-16 with the factory installed decoder.

If I remember correctly, the numbers are silk screened on the lightboard. Just follow what is printed on the board compared to the wiring chart in the manual.

And here is why I brought this up, gear of skip.  The board on this loco has those numbers and the 7 is on the front end and the 8 is toward the cab.  I hope Mr. Bochmann comes back and verifies if I should follow the literature or the numbers on the board.

The chuff sensor wire does not have to be used.  The decoder will run fine without it attached.

Dear All,
The above information is correct. As with most N Scale locos, there is not room for a plug/ socket and a decoder, so hard wiring the N Scale decoder of your choice is the way to go.
Have fun!

Thanks for your reply, Mr. Bachman.  I have another question for you.  The literature in the model shows the board to wire in the decoder.  The literature says the wiring contacts on the board are on the engineer side of the loco in cab forward configuration.  The actual model has the contacts on the fireman side of the loco in cab forward.  Is this correct or is the decoder up side down?  Also, it shows the numbering to be 8, 1, 2, 3, 4, 5, 6, 7 in order from the long hood end.  Is that correct or is there another order I should follow?

Thanks for the reply from TCWorld.  Now I would really like to have that verified from Mr. Bachmann.  He has been absent here.

I understand that you can install a .010 shim on the bearing block and rotate the block on re-installation so that it is up against the frame.  This will lower the drive axle so that there is more load on it.  I should have included that I am refering to the driver that has the traction tire.  Putting more load on the traction tire increases traction.  This should give the loco the ability to pull over 20 cars by itself.  The 2-8-0 and the 4-8-2 heavy mountain do not have this problem and pull great.

I am aware of hard wiring a decoder such as the M-1.  I would actually use the CTS Z2 for this application.  I am asking the question to make sure there is not a dedicated drop in decoder for this loco before I use the hard wiring approach.

Helping a friend with a N scale H-16-44 diesel item no. 61456.  Literature with model shows some things about DCC but does not identify candidate decoders.  Which one should I use Mr. Bach Man?
