Electrical System: Service and Repairs
14. After you make the connections, apply battery terminal protector Toro Part
No. 107-0392 or a light layer of grease to the battery terminals and cable
connectors to reduce corrosion; refer to
2–13). Make sure that all terminal boots are positioned over all cable
connections.
15. Install the battery covers before returning the machine to service.
1. Clean the batteries with clean water and a towel. Do not use solvents or
chemicals to clean the batteries.
2. Check the battery case for cracks. Replace the battery if cracked or leaking.
3. Check the battery terminals and cables for corrosion and clean them as
necessary. Use a battery terminal protector to reduce corrosion; refer to
Battery Terminal Protector (page
4. If the 48V system battery voltage drops below 50 VDC, battery inspection
and/or charging may be necessary.
5. Use a digital multimeter (VDC) to measure the voltage of each battery
individually.
Note: This test provides a relative condition of the battery. Load testing of
the battery provides additional and more accurate information.
A. Disconnect the cables from the terminals of the battery being tested.
B. Measure and record the battery voltage. Refer to the following table to
determine charge level of the battery.
Battery Test Table
Voltage Measured
12.68 VDC (or higher)
12.45 VDC
12.24 VDC
12.06 VDC
11.89 VDC
Note: When testing the 48V system batteries, the voltage should be
consistent across all 4 batteries. If the voltage of any of the batteries
varies by more than 10%, it indicates a problem with the battery that
has the lower voltage.
6. A battery load tester can be used to test individual batteries.
Follow the manufacturer's instructions when using a battery load
tester.
