Inspecting, Maintaining, and Testing the Battery (continued)
H. Use the Minimum Voltage Table (page 5–64) , determine the minimum
voltage for the center cell electrolyte temperature reading.
Minimum Voltage Table
Minimum Voltage Battery-Electrolyte Temperature
9.6 70°F (and up) 21.1°C (and up)
9.5 60°F 15.6°C
9.4 50°F 10.0°C
9.3 40°F 4.4°C
9.1 30°F -1.1°C
8.9 20°F -6.7°C
8.7 10°F -12.2°C
8.5 0°F -17.8°C
I. If the test voltage is below the minimum, replace the battery. If the test
voltage is at or above the minimum, return the battery to service.
Installing the Battery
IMPORTANT
To prevent possible electrical problems, install only a fully charged
battery.
1. Ensure that the key switch and all accessories are in the O
FF
position.
2. Ensure that the battery compartment is clean and paint it if necessary. Place
the battery tray in position.
3. Ensure that all the battery cables, battery retainer, and electrical connections
are in good condition.
4. Place the battery in its compartment. Ensure that the battery is level and flat.
Connect the positive (+) cable connector onto the positive (+) battery post.
Use 2 wrenches to attach the cable bolt and locknut.
5. Attach the battery retainer with the flat washer and flange nut.
Note: Do not overtighten the nut to prevent cracking or distorting the battery
case.
6. Connect a digital multimeter (set to A) between the negative (-) battery post
and the negative (-) cable connector. Ensure that the reading is less than
0.1 A. A reading of more than 0.1 A usually indicates a damaged switch, a
shorted circuit, or grounded wire. Identify and repair the electrical faults
before returning the machine to service.
7. Connect the negative (-) cable connector to the negative (-) battery post. Use
the 2 wrenches to attach the cable bolt and locknut.
8. After you make the connections, apply battery terminal protector (Toro Part
No. 107-0392) or a light layer of grease on all the battery posts and cable
connectors to reduce corrosion.
