Battery Maintenance
Battery maintenance is important. Checking the condition of a battery at regular intervals will help insure its
proper operation. Here are some recommendations for checking and servicing batteries:
Note: These instructions only apply to batteries other than maintenance-free batteries. Do
not open or break seals on maintenance-free batteries.
1. Keep the battery mounted securely. Vibration causes early failure of many batteries.
2. Check the electrolyte level of the auxiliary batteries at regular intervals. Keep each cell filled
to just above the plates with distilled water. Once the plates have dried out, they cannot be
reactivated, and the capacity of the battery is reduced in direct proportion to the area of plate
surface that has become dry. This kind of damage can occur quickly; usually it can happen
overnight. If the fluid level is low, simply add distilled water.
3. Keep the battery clean. Corroded terminals make poor contact and do not allow the chassis
alternator or the converter to bring the battery up to full charge. Battery sulfation occurs
when the battery has been standing in a discharged condition over a long period of time,
or when the battery has been operated continually in a state of partial discharge. Use a
baking soda solution to neutralize the acid accumulations on the battery top. Do not allow
the soda solution to enter the battery. Make sure the vent caps are secure. Flush with water.
Thoroughly dry all cables and terminals, reinstall, and use a plastic ignition spray to protect the
terminals.
4. Check the outside condition of the battery. Look for cracks in the case or vent plugs. If the
case is cracked, the battery must be replaced. If the vent plugs are cracked, they must be
replaced.
5. Watch for overcharging. Three indications of overcharging are:
a. Active material on the vent cap (heavy deposit of black lead-like material on the
underside of the vent cap) .
b. Excessive use of water.
c. Voltage regulator output.
6. Make sure the battery hold downs and carrier are kept clean and free of corrosion.
When removing a battery, disconnect the ground battery clamp first. When installing a battery, always connect
the grounded battery clamp last.
When a battery needs to be replaced, make sure to replace it with a battery of the same characteristics as the
original equipment. Consult your dealer for advice on battery replacement.
Battery Isolator Controller
When the motor home engine is not running, the chassis and auxiliary batteries are kept separated from each
other within the electrical system through the use of a battery isolating controller. The controller prevents the
auxiliary batteries from discharging the chassis battery when the motor home is parked.
Some additional characteristics of the isolator system include:
1. Delays connecting the auxiliary batteries to the charging system for approximately 15 seconds,
to allow the alternator time to reach full charging ability.
2. After this initial time delay, if the alternator has come up to full charging ability, (13.2 Volts) the
isolator will electrically connect the auxiliary and chassis batteries together for charging.
3. If the charging voltage drops below 13.2 Volts for a period of 4 seconds due to low idle speed
and or excessive load, the isolator will disconnect the auxiliary batteries until the voltage
returns to a level of 13.2 volts for about 10 seconds.
4. In the event the automotive battery is discharged, it will be necessary to press and hold the
Start Switch located in the dash.
