yes, I went through the motors before posting anything here.
what I did find that is a substantial draw, is going through the motor direction wiring board that also contains the A/C power that powers the mars light board. (two resisters across the A/C power),I disconnected it for testing purposes. (it took the resistance down to .7 at low speed operation and up to 1.5 at high speed.)the temp stayed down real well, I ran it for at least 3 hours at a scale 35 mph, it gradually got warm, unless I lowered the speed and it would cool back off again.
As you said it has too much draw for that motor driver.
it was a fun experiment .
I placed my order for two ERR 8amp drivers, I will un-tether the loco's and lash them up independent of each other.
