4.5.10.3.1.2 Control wiring and ground used as test points.
4.5.10.3.1.2.1 Charging motor. Tie all charging motor leads together and apply 900 volts between lead bundle
and charging motor housing.
4.5.10.3.1.2.2 All other secondary disconnect control wiring. With the circuit breaker closed, the voltage shall
be applied between secondary disconnect control wiring of the same voltage rating and test points as marked with an
