Relays

There are four relays in the Z580 and Z589 liquid cooled
Kawasaki DFI.
Relays have 4 functions in the Z580 and Z590 Liquid
Cooled models:
• Start Relay
• Kill Relay
• Fan Relay
• Fuel Pump Relay

Purpose

1. Start Relay: If all conditions of the safety system
are met, the start relay will activate allowing current
to flow to the starter solenoid when the ignition is in
the "start" position.
2. Kill Relay: If any of the conditions of the safety
circuit are not met during operation the kill relay is
de-energized which will ground the ignition coil. Also,
when turning the ignition switch to the "OFF" position
the kill relay will de-energized which will ground the
ignition coil.
3. Fan Relay: Activates when the ignition switch is in
the "RUN" position, energizing the cooling fan.
4. Fuel Pump Relay: Activates when the ignition
switch is in the "RUN" position, providing 12VDC to
the fuel pump.
