GGG - you wrote info below on 1-16-14, I believe. I'm interested!!

I have searched but couldn't find this particular discussion anywhere - I found the opposite, running a DC motor on an LCRU  Any chance you could point me in the right direction? I would like to run a single Pullmore motor on an E103 e-unit. I will use heat sinks on the driver transistors.

"There is a method to use a DC motor reverse unit with a bridge rectifier to keep the current flowing in the same direction through the field while polarity of the brushes is reversed.  I have done this with the Lionel 103 e-unit on a single AC motor Alco.  Runs fine.  Just lower top speed.  If interest I will post directions.  G"

Before using the electronic unit, try this with a DC HO or G power pack that has a reverse switch in place of the e-unit motor leads to see how this works, and check the current draw with an ammeter, so you can get a good indication of just how much amperage this scheme draws and to assess the performance.  My guess is, that while it all works, you may not be impressed with amount of current or the decrease in performance.

Understood, will do - thanks again.
