Power Supply Block

FIG. 17: Power Supply Block

Chassis power supply block is located on panel next to

master module. This block receives power (1) from 100

amp circuit breaker in battery box next to master

battery disconnect switch. Power block receives ground

(2) from master battery disconnect switch in battery

box. Purpose of this divider block is to split power and

ground to be used by I/O module and 4-pack relay

module. Power and ground are split to 12 sources.

4-Pack-relay module (3) is located on right side of

interface enclosure under flasher module. Usage is as

follows:

4P1 - Lower Mounted 4-Pack Module

Relay 1 - park Brake ON Ground
