Hi Larry and Ross,
I want to be sure I’m understanding this correctly:
The simple act of pushing through the points won’t cause the short. In other
words, if you push a car with regular wheelsets through the points it won’t
cause the electrical connection to switch from the straight to the curve or
vice versa. The problem is only when the motor pushes through. This is
because the motor has two wheels on each side that are directly connected to
each other inside the motor. When one of these wheels makes it to the
straight part while the other is still in the curve you’ll end up with a
momentary short inside the motor. This is caused by the fact that the two
wheels on each side are directly connected.
Is this correct? I recently tried a similar setup for a reversing loop that
worked on the same principle as this one. I thought I could always avoid a
short by careful switch settings but hadn’t realized this issue with the
motor causing the short until I read this thread. I think I’ll stop doing it
now since I’m not interested in shorting the life of my motors.
Thanks,
Paul

Shorting the power should have no effect at all on the motors. It’s the
controller that people are worried about. And these should be fine as well. The
circuits are short circuit protected for short durration, and as long at the
controller isn’t connected right next to the loop, the track and wire serve as a
ballest of sorts as well.
