OPERATION / MAINTENANCE MANUAL

A-2E. ELECTRICAL SYSTEM
The following topics describe care and maintenance of the electrical system components.
These components functioning together produce the energy needed for operating the
electrical equipment on the engine and each is dependent upon the others for satisfactory
operation. In the event of failure or improper operation, it is essential to check the entire
electrical system as a defect in one component can cause damage to another. Many electrical
` system problems can be traced to loose or corroded connections. Keep connections tight and
make sure the wiring insulation is in satisfactory condition. Most of the electrical system
testing can be performed while the components are on the engine. It should be remembered,
if a malfunction is found on test, the component must be removed for further testing, repair
or replacement.
Battery
Every 250 hours check the electrolyte level of each cell and the general condition of the
battery. Maintain the electrolyte level to the base of each vent well. The make-up water must
be one of the following (in order of preference):
1. Distilled water.
2. Odorless, tasteless drinking water-
3. Iron free water.
WARNING: Never add acid or electrolyte.
Cleaning Battery
Mix a weak solution of baking soda and water. Apply the solution with a soft bristle brush.
Be careful not to get cleaning solution into the battery. Thoroughly rinse the battery and
battery tray with clean water. Apply grease to battery cable clamps and terminals and to all
threads.
-Installing Battery
1. Be sure the battery tray is clean and free of foreign objects.
2. Be sure terminal posts and cable clamps are clean.
3. Place the battery in the tray. Tighten the hold down clamps evenly until the battery is snug.
Do not over tighten.
4. Connect the "hot" terminal first. Be sure the top of the cable terminal is pushed down even
with the top of the terminal post. Tighten the clamp firmly.
WARNING: Always connect the "hot" terminal first to minimize arcing. Otherwise injury
or damage could result.
5. Connect the "grounded" terminal last. Be sure the top of the cable terminal is pushed
down even with the top of the terminal post. Tighten the clamp firmly.
