Electrical System: Service and Repairs
Groundsmaster 5900/5910 machines use two (2) separate electrical systems.
Most machine functions operate on a typical 12 VDC system. Two 12 Volt
batteries located at the rear of the machine are connected together in parallel to
support the 12 Volt electrical system. The second system exists to operate the
electric cooling fans and is 24 VDC. Two 12 Volt batteries located at the rear of
the machine are connected together in series to support the 24 Volt cooling fan
circuit. See Electrical System Operation (page 6–7)
If the machine will be stored for more than 30 days:
1. Remove the batteries and charge them fully (see
6–139)).
2. Either store batteries on a shelf or on the machine.
3. Leave cables disconnected if the batteries are stored on the machine.
4. Store batteries in a cool atmosphere to avoid quick deterioration of the
battery charge.
5. To help prevent the batteries from freezing, make sure they are fully charged
(see Battery Service (page
1. Battery electrolyte level must be properly maintained. The top of the battery
must be kept clean. lf the machine is stored in a location where temperatures
are extremely high, the battery will discharge more rapidly than if the machine
is stored in a location where temperatures are cool.
Wear safety goggles and rubber gloves when working with
electrolyte. Charge battery in a well ventilated place so gasses
produced while charging can dissipate. Since the gases are
explosive, keep open flames and electrical sparks away from
the battery; do not smoke. Nausea may result if the gases are
inhaled. Unplug charger from electrical outlet before connecting or
disconnecting charger leads to or from battery posts.
2. Check battery condition weekly, after every 50 hours of operation or every 30
days if machine is in storage. Keep terminals and entire battery case clean
because a dirty battery will discharge slowly.
A. Clean battery by washing entire case with a solution of baking soda and
water. Rinse with clear water.
B. Coat battery posts and cable connectors with Battery Terminal Protector
(Toro Part No. 107−0392) or petroleum jelly to prevent corrosion.
3. Battery cables must be tight on terminals to provide good electrical contact.
