4g. The DVOM should read less than 1 Ohm.
4h. Reverse the leads. See Figure 2.33.
4i. The DVOM should read open line or “OL”.
4j. If either reading varies from the values listed
above, replace the harness.
5. If all the components in the switch box are work-
ing properly and battery voltage still does not get
to the motor, replace the harness.

Batteries and charger
Batteries
Before an electrical system can be diagnosed, the bat-
tery must be fully charged and in good working order.
Charging the battery
NOTE: Batteries on most modern outdoor power
equipment are 12 volts. This mower uses a bank
of four, sealed 12 volt lead-acid batteries. The
four act as one and should be looked at and
treated as one big battery.
IMPORTANT: Do not replace individual batter-
ies. Replace all four batteries with new batteries
that are the same age. This will prevent weaker
batteries overworking the strong batteries and
prolong the life of all of them.
IMPORTANT: The voltage of the battery bank is
over 48 volts for a fully charged battery bank. To
ensure that the batteries in the battery bank are
evenly charged, only use the charger that came
with the mower.
To test the battery pack:
CAUTION: The mower must run in order to test
the battery pack, move the mower to a safe loca-
tion when operating it.
NOTE: The battery charger will charge the bat-
teries to a voltage higher than then can maintain
on their own. Once the charger is unplugged, the
battery pack will start to bleed of excess voltage.
Allow 10 minutes for the batteries to normalize
after unplugging from a charger before measur-
ing voltage.
1. Remove the motor cover by following the steps
described in Chapter 3: Repair Procedures.
2. Attach a DVOM to the harness by back probing
where the connection at the battery pack and
place the DVOM in a secure location.
NOTE: Make a note of the battery voltage at this
point. A fully charged battery will read between
50.4 - 54.0 volts.
