Batteries give off flammable fumes which can ex-
plode.
To avoid injury or death, do not strike a match,
cause a spark, or smoke in the vicinity of a battery.
Test Step 1. Check The Batteries.
•
Measure no-load battery voltage at the battery
posts.
•
Load test the batteries.
Note: The batteries must pass the load test. The
minimum voltage must be 11.5 volts for a 12 volt
battery. If the battery voltage of a 12 volt battery
is below 12.4 volts then the battery needs to be
charged.
Expected Result:
If the batteries are OK proceed to Test Step 2.
Results:
• Not OK – Recharge or replace the batteries. Verify
that the repair eliminates the problem. STOP.
