Connector Voltage
1. Connect the battery negative code, then measure the voltage
with a voltmeter across the a terminal and chassis.
2. If the voltage differ from the battery voltage, the wiring harness
is damaged.

Beacon Switch Continuity
1. Measure the resistance with ohmmeter across the a terminal (1)
and c terminal (3), and across the d terminal (2) and e terminal
(4).
2. If the measurement is not following below, the beacon switch or
the bulb are damaged.
