Location
The recovery boosters are located inside the trunk
on the center of the component brackets just above the
solenoid valve.
Test Procedures
1. Disconnect the brewer from the power source.
2. Disconnect the white and black wires from the coil
of the recovery booster relay.
3. With a voltmeter, check the voltage across the
white and the black wires. Connect the brewer to
the power source and initate a brew cycle. The
indication must be 120 volts ac.
4. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #5.
If voltage is not present as described, refer to
Wiring
Diagrams
and check the brewer wiring harness.
5. Check the continuity across the recovery booster
relay coil terminals.
If continuity is present as described, reconnect the
white and black wires to the coil.
If continuity is not present as described, replace the
recovery booster relay.
6. Disconnect the blue and black wires from the relay
contact terminals. Connect the brewer to the power
source. With the "ON/OFF" switch in the "ON"
position and the start switch pressed and released,
check for continuity across relay terminals.
7. Disconnect the brewer from the power source.
If continuity is present as described, reconnect the
blue and black wires to the relay contact terminals.
If continuity is not present as described replace the
relay.
Removal and Replacement:
1. Remove all wires from the recovery booster relay.
2. Remove the two #8-32 screws securing the relay
mounting bracket to the component bracket. Re-
move relay bracket and relay as an assembly.
3. Remove the one #6-32 screw securing the relay to
the relay mounting bracket.
4. Using one #6-32 screw install new relay on relay
mounting bracket.
5. Using two #8-32 screws install relay and bracket
to the component bracket.
6. Refer to Fig. 9 when reconnecting the wires.
