Testing the Vehicle Battery, Continued:
4. Place the red (+) probe of a multimeter, set at Volts - DC, 20 volt range, on the positive (+) post and
place the black (-) probe on the negative (-) post of the battery and take a voltage reading. If it shows
less than 12.4 volts, or if the lowest specific gravity reading from Step 3 is less than 1.225, recharge the
battery. If battery voltage is greater than 12.4 volts and specific gravity is greater than 1.225, the prob-
lem is not with the battery. If the battery does not reach 12.4 volts, or if the specific gravity of a cell is
still less than 1.225 after charging, replace the battery. See NOTE below.
5. Connect a 160 ampere load tester to the battery.
6. After 15 seconds, read the voltage and then disconnect the load tester from the battery. If the voltage
reading is below the required minimum (See Load Test, Page 130), replace the battery.
7. If the battery is found to be good, or if the electrical problem continues after the battery has been
replaced with a good one, test the electrical circuits.
TESTING THE STARTER CIRCUIT AND THE GENERATOR CIRUIT
Use the chart below (Figure 12-12) as a starting point for troubleshooting problems with the starter and gen-
erator circuits.
• A FULLY CHARGED BATTERY THAT IS IN GOOD CONDITION SHOULD HAVE A SPECIFIC
GRAVITY OF AT LEAST 1.225 IN ALL CELLS, AND THE DIFFERENCE IN THE SPECIFIC GRAV-
ITY OF ANY TWO CELLS SHOULD BE LESS THAN 50 POINTS. OPEN CIRCUIT VOLTAGE
SHOULD BE AT LEAST 12.4 VOLTS.
