The ammeter shows the rate at which the battery is being charged or discharged. The Delcotron charg
ing system is equipped 'with a regulator which con
trol s the charge acco rding to battery requirements.
When the Delcotron generator is supp lying more
than the curre nt demand, the ammeter will show the
chargi ng rate while a disc harg e will be shown if
the
current demand is more than the Delcotron output.
With the battery fully charged , the charging rate will be 1m-\', thus giving an indication of battery condition.
OIL PRESSURE
GAUGE
...
The oil pressure gauge indicates the pressure at which
oil is being delivered to the various parts of the en·
gine requiring lubrication. Pressures registered by the
AMMETER
•
gauge
may vary acco rding to outside air temperatures or weight of oil being used. Oil pressure of a cold en
gine being operated at a given speed will be somewhat
higher than when the engine is at normal operating
temperature at the sam e speed. Prolonged high speed operation on a hot day at the giv en speed will result in somewhat lower oil pressure readings. Readings of 30 to 40 psi may be considered normal during moderate road speeds of 35 to 40 mph with the en
gine at proper operating temperature. Gauge read
in gs whi ch are consistently high or low under these
co nCIitions may ind i cate lubrication system and/or
engine malfunctions.
