Relay

(AW325)
The relay is responsible for supply of power to the
motor, and has numbers adjacent to its male termi-
nals for reference of voltage received and supplied
for troubleshooting.
Refer to Fig. 20 and the following table for connec-
tion of wiring and voltage checks.
Terminal Function
2 120 volts from relay to motor
4 120 volts to relay from power supply
6 120 volts from relay to motor
8 120 volts to relay from power supply
0 120 volts from ignition controller
to relay for relay coil closure
1 Neutral for relay
If the relay is receiving 115 volts at terminal 0 from
the ignition control, along with incoming power
supply voltage on terminals 4 and 8, but voltage is
not supplied to the motor from terminals 2 and 6, the
relay is defective.
