Section XIII RELAYS, CIRCUIT BREAKERS, AND WIRE IDENTIFICATION
2-34. INTRODUCTION.
a.
The electrical relays are identical in all M915 thru M920 vehicles, except for minor
variations in arrangement. The M917, M918, and M919 use two relays, the M915
use seven relays; while the M916 and M920 use eight.
b.
The circuit breakers are identical in the M915 thru M920 vehicles, except for minor
variations in arrangement. The M917, M918, and M919 use six circuit breakers to
protect their electrical systems, the M915 uses eight; while the M916 and M920 use
nine. These circuit breakers are rated at 20 amps continuous load. If an overload
does occur, the circuit breaker automatically recycles (opens and closes) until the
overload is removed.
