Next, verify that each motor terminal is electrically isolated from the left and
right rail pickups using an ohmmeter or continuity tester:
1. With your meter set to the ohms scale, touch both meter probes together
and note that the meter indicates 0 ohms (short circuit). You don’t want to
see this indication again!
2. Touch one of the probes to one of the motor brush terminals.
3. Touch the other probe to the locomotive frame, then the left rail power
pickup wire, and finally to the right rail power pickup wire.
4. Move the first probe to the other motor brush terminal and repeat the
tests. If all tests indicate an open circuit, the motor is properly isolated.
Do not proceed further until this is done.
You will also need to disconnect the wires leading to any lights you wish to
use. Using an ohmmeter, check that each lamp lead is electrically isolated
from the frame as well as the left and right rail pickups.
