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.
When the motorhome 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 motorhome 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.
Note:
When operating 12 Volt equipment from battery, reduce equipment
in use to conserve battery. Gradual dimming of lights, and slowing of
motors indicates low battery voltage.
ALWAYS WEAR SPLASH PROOF SAFETY GLASSES
WHEN WORKING WITH BATTERIES.
