GASOLINE VEHICLE - TROUBLESHOOTING
AND ELECTRICAL SYSTEM
TEST PROCEDURE 17 – Battery Test (Under Load)
NOTE:
Keep the battery connected while performing this test procedure.
The voltage reading listed is for electrolyte at 70 °F (21 °C). At lower electrolyte temperatures the voltage
reading will be lower.
1.
If necessary, see Testing Basics.
2.
Set the Forward/Neutral/Reverse control (FNR) to N.
3.
Set the Maintenance/Operate switch to MAINTENANCE.
4.
Put chocks against the wheels.
5.
Set a multimeter to 20 VDC.
6.
Put the red (+) probe on the F2 (white wire) terminal on the starter/generator
3030C

Battery Test (Under Load)
7.
Put the black (–) probe on the negative (–) battery post.
8.
Turn the key switch to ON.
9.
Make sure that the FNR is in N, and push the accelerator pedal.
NOTE:
With the accelerator pedal pushed, the battery is under load.
9.1.
If the voltage reading is over 9.6 volts, with an electrolyte temperature of 70 °F (21 °C), check the
starter/generator.
9.2.
If the reading is below 9.6 volts, with an electrolyte temperature of 70 °F (21 °C), check the battery.
9.3.
If the reading is zero, there may be no continuity across the large posts of the solenoid. Check the solenoid.
9.4.
If all of the test results are good and the voltage reading is zero, there may be a broken or damaged
white wire from the solenoid to the starter/generator.
10.
If all of the test results are good and the voltage reading is zero, there may be a broken or damaged white wire
from the solenoid to the starter/generator.
