Storage Battery—The Storage Battery is carried in a
compartment underneath the right front seat.
box, the battery must be disconnected first of all. Otherwise,
there is a possibility of the loose connections being shorted
or grounded in a way that will reverse the generator polarity
or otherwise damage the charging circuit.
The battery is filled with an acid solution from which the
water slowly evaporates, making it necessary for fresh distilled
water to be added to each of the three cells at regular
intervals to bring the level up to the bottom of the filling
tubes. Distilled water should be added at least every
1000 miles and, in warm weather, every 500 miles or at
least every two weeks. Hydrant water or water that has
been in contact with metallic surfaces is not satisfactory.
After adding water to the storage battery in freezing
weather, the car should immediately be run far enough to
mix the water with the acid solution thoroughly. If the
car is parked immediately after water is added, the water
is likely to stay on top of the acid solution and may freeze,
thus causing extensive damage to the battery.
CAUTION: Whenever disconnecting any wires in the
generator circuit or in the harness opening at the regulator

lights on the car, the same candle power bulb should be used
for replacement as was originally installed. It is a good plan
