….With just the drivetrain friction, current should be in the 0.1 to 0.2A range.
In the case of this engine, I was a bit appalled when I measured a starting voltage of over 2.5V and current of about 0.7A!

so how big is this 4 amp draw then? Wow. I could see if there were multiple motors inside or with a smoke unit stuck on. If only one, this motor must be terrible? Is there binding or wheels out of quarter? Poor gearing? Just wow.

When you run in conventional, I believe the draw is higher than in command? Most decoders that I've installed, tame down the amp draws and the motors behave much better.
