Deck System Resistance Test Procedure
Make sure your Digital Multimeter is capable of
measuring up to 1.2 million ohms(Ω) resistance
before beginning these steps. Refer to your Digi-
tal Multimeter Owner's Manual for correct dial
settings.
Always disconnect the batteries before perform-
ing any maintenance or repair.
Wait 5 minutes after disconnecting the batteries
before working on the machine.
1
Remove any debris build-up from all deck com-
ponents.
2
Verify all power connections on deck motors and
deck controller are torqued properly. If loss con-
nections are discovered, tighten to the correct tor-
que values found in service and repair manual.
Reconnect the batteries per the instructions in the
service and repair manual and check for proper
deck operation. If loose connections are not
found, proceed to step 3.
3
Label all (8) deck controller connection points on
the edge of the deck controller housing so they
are easily viewed for correct re-connections.
4
To ensure correct re-connection, mark all (8) wire
connections with the corresponding connection
point labels from step 3.
5
Remove all (8) wire connections from the deck
controller.
6
Measure deck controller resistance (Ω) : (A)
Place the negative (-) probe of a digital multime-
ter on the positive (+) battery terminal of the deck
controller. (B) Place the positive (+) probe of the
digital multimeter on deck controller terminals
AR, then CR. Resistance for each should read be-
tween 270K (Ω) and 330k (Ω). If resistance is
above or below the specified range, the deck con-
troller will need to be replaced. Repeat process
for deck controller terminals AL, BL and CL.
