Open up the 610 switcher Dennis. The field coil is mounted right on the truck and forms an integral part of the frame. Check continuity and check that e-unit. And also check the other collector truck with the rollers.

Bypass the e unit. Green goes to the field tab in the middle, blue to one brush holder, and yellow to the other.

Jumper one brush holder to the field tab, attach one test lead to the other brush holder. Touch the other test lead to metal side of motor. Reverse the brush holder wires and it should run in the opposite direction.

You can bypass the e-unit in the other engine the same way.
