5. Using an 87a relay, the 30 post and the
87a post are common. When the coil is
tripped, the 87a post becomes inactive
and the 30 post becomes common to
the 87 post located on the outside of the
relay.
A Single Pole
Single Throw
relay (SPST) is an
electro-magnetic
switch consisting of
a coil (terminals 85
& 86), one common
terminal (30),
one normally closed terminal (87a), and one
normally open terminal (87).
When the coil of the relay is at rest (not
energized) the common terminal (30) and the
normally closed terminal (87a) have continuity.
When the coil is energized, the common terminal
(30) and the normally open terminal (87) have
continuity.
NOTE
When there is power applied to the coil,
the coil sets up a magnetic field in the
windings. When the power is removed,
the field collapses. A momentary high
voltage discharge will occur. This is how
an ignition coil works.
alternator
The alternator
is designed for
output through the
engine operating
range. When
traveling, keep
an eye on the
voltmeter in the
dash area. Normal
readings should be between 13 to 14.5 Volts DC.
Voltage indications higher or lower indicate a
potential problem with the charging system. If
the alternator output drops below an acceptable
level, a charge indication warning lamp will
illuminate.
The alternator replaces amp hours the chassis
battery used to start the engine. The amount of
charge the alternator sends to the chassis battery
is dependent on the amount of time the engine
is operated. Repeatedly starting the engine for
short periods may not be enough operating time
to adequately replace the amp hours the chassis
battery uses to start the engine.
The function of the alternator is an electrical
system voltage maintainer, not a battery charger.
When the engine is operating, the alternator
maintains electrical system voltage relative to a
load, such as headlights and windshield wipers.
When a heavy load is placed on the alternator,
such as trying to charge dead house batteries,
the operating temperature of the alternator will
increase. Excess operating temperature of the
alternator for extended periods of operation can
lead to premature failure of the alternator.
NOTE
The alternator is not designed to charge
the house batteries from a complete
discharge to a full state of charge. The
alternator will maintain the battery
charge during travel, supplying the DC
current necessary to operate running
lights or other DC loads.
If the house batteries are in a low state of
charge, it is recommended to charge the house
batteries with the converter/inverter or an
auxiliary battery charger before driving the
motorhome.
CAUTION
Long-term use of the inverter to operate
the microwave while in transit will
damage the alternator. Use the generator
to operate the microwave while in
transit.
