If I use the 44912 for G scale DC and keep the voltage at 20 volts, will the unit work?

How do I uncouple the cars either automatically or manually?

I removed and replaced the jumpers per the instructions and the engine acts the same.  Thanks for your help.  I'll live with it.  Happy Thanksgiving.

I will check it again.  The diagram provided shows the jumpers to connect 8-1-and 2. and the other jumper  4-5-and 6.

I am using a DC power pack.  My other Bachmann locomotive a Porter 0-4-2, which is non DCC starts at a low voltage setting.  The 0-4-0 side rod mechanical, which says DCC has instructions on how to remove the DCC module and replace it with dummy jumpers.  Which I have done.  The issue is the engine starts like a rabbit and requires a higher voltage setting.  The question is this.  Is this normal, or should I reinstall the DCC module?  I don't want to burn the DCC module out if that is the result of running it on straight DC.

Can I reinstall the DCC and try running the engine in conventional DC mode?  Will that damage the DCC?

I installed the dummy plugs per the instructions, but the engine has a high start up speed and very little speed difference between low throttle and high throttle.  Is there something I missed or is this just the way it works in conventional mode?

Is the load removable?  I would like an empty car.
