FUSE / RELAYS
RELAY OVERVIEW
Relays use low current circuits to control high current
circuits. The low current circuit flows through a coil
winding, which magnetically attracts the contact to close
the high current side, allowing that side of the circuit to
flow current.
CHASSIS RELAY
The chassis relay provides power to the following
systems:
• Head Lights / Tail Lights / Brake Light
• AWD Coil / ADC Coil / RH Drive Switch
• Accessory Power Points
