Electrical System Operation
Additional Battery Maintenance Suggestions
1. Perform monthly inspections of the batteries’
external condition. Look for cracks in the
covers and cases.
2. Ensure batteries are securely fastened in
the proper position.
3. Make sure battery clamps are tight and free
from corrosion.
4. Keep the batteries and terminals clean. Acid
and dirt accumulation can prevent sufcient
current from owing through the cables,
and can permit current to ow between the
terminals causing the batteries to discharge.
Do not allow battery electrolyte to contact
skin, eyes, fabrics, or painted surfaces.
The electrolyte is a sulfuric acid solution
which could cause serious personal injury
or property damage. Wear eye protection
when working around batteries.
5. Clean the battery with a solution of baking
soda and water to neutralize any acid
present, then ush with clean water. Foaming
around terminals or on top of the battery is
normal during the cleaning process.
NOTICE
Do NOT allow any baking soda solution to
get into the battery. This can neutralize the
battery acid.
6. Dry the cables and terminals before
reinstalling them. Do NOT apply grease to
the metal surfaces inside the cable terminals
to prevent corrosion. Grease is an insulator
and will prevent the ow of electricity. Use a
plastic ignition spray to protect the terminals
after you have cleaned and reinstalled them.
Warning
Caution
NOTE: When removing, replacing,
boosting, or charging the batteries,
ensure the red positive (+) cable
terminals are connected to the positive
(+) posts, and the black negative (-)
cable terminals are connected to the
negative (-) posts.
7. If installing batteries or booster/charger
cables, attach the red positive (+) cable
terminals rst, then attach the black negative
(-) cable terminals.
8. If removing batteries or booster/charger
cables, remove the black negative (-) cable
terminals rst, then remove the red positive
(+) cable terminals.
9. Do NOT attempt to recharge frozen batteries.
10. If using a battery quick-charge unit,
disconnect the cables from the batteries.
NOTICE
Do NOT attempt to start the engine using a
battery quick-charge unit.
11. If you do not have maintenance-free
batteries, check the battery uid level and
ll with distilled water if necessary. Do not
overll.
12. Have the specic gravity of the battery uid
checked during regular motorhome service
and maintenance.
Remove rings, metal watchbands, and other
metal jewelry before working around a
battery. Use caution when using metal tools.
If the tool contacts the battery terminals or
the metal connected to them, a short circuit
could result.
