TEST PROCEDURE 1 – Battery
See General Warnings on page 1-2.
DANGER
• Due to the danger of an exploding battery, wear a full face shield and rubber gloves when working near
a battery.
• Battery – Explosive gases! Do not smoke. Keep sparks and flames away from the vehicle and service
area. Ventilate when charging or operating vehicle in an enclosed area. Wear a full face shield and
rubber gloves when working on or near batteries.
• Battery – Poison! Contains acid! Causes severe burns. Avoid contact with skin, eyes, or clothing.
Antidotes:
– External: Flush with water. Call a physician immediately.
– Internal: Drink large quantities of milk or water. Follow with milk of magnesia or vegetable
oil. Call a physician immediately.
– Eyes: Flush with water for 15 minutes. Call a physician immediately.
NOTE:
The battery must be properly maintained and fully charged in order to perform the following test procedures.
Battery maintenance procedures, including watering information and allowable mineral content, can be
found in section
Gasoline Vehicle - Electrical Components on page 19-1
of this manual.
1.
Place the Forward/Reverse handle in the NEUTRAL position and the neutral lockout switch in the MAINTENANCE
position. Chock the wheels.
2.
Check for loose or corroded battery terminal connections. Remove the negative (–) cable first and clean, tighten,
and replace connections as necessary.
Voltage Test
1.
Take a voltage reading with a multimeter set to 20 VDC by placing the red (+) probe on the positive (+) battery
post and the black (–) probe on the negative (–) battery post. If it shows less than 12.4 volts, recharge the battery.
If battery voltage is greater than 12.4 volts, the problem is not with the battery. If the battery does not reach 12.4
volts after charging, replace the battery.
See following NOTE.
NOTE:
Open circuit voltage should be at least 12.4 volts.
Load Test
1.
Connect a 160-ampere load tester to the battery posts.
2.
Turn the switch on the load tester to the ON position.
3.
Read the battery voltage after the load tester has been turned ON for 15 seconds. Compare the battery’s voltage
reading with the following table. Make sure you have the correct ambient temperature.
