Alternator; Check Out Procedure - Monaco DIPLOMAT 2004 Owner's Manual

The Leece-Neville alternator with integral rectifier, regulator and remote
voltage sensor is designed for reliable output throughout 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. Voltage indications higher or
lower indicate a problem with the charging system. If the alternator output
drops below an acceptable level, a charge indication warning lamp will illu-
minate.
The alternator charges or maintains the chassis battery used to start the
engine. The amount of charge to the batteries is dependent on the amount of
time the engine is operated. Repeatedly starting the engine and driving the
motorhome for a short distance, or short periods, may not be enough operat-
ing time to adequately recharge the battery used to start the engine.
The alternator also maintains a charge to the house batteries. The function
of the alternator is an electrical system voltage maintainer, not a battery
charger. When traveling, the alternator maintains electrical system voltage
relative to any loads, such as headlights and windshield wipers. When a
heavy load is placed on the alternator, such as trying to charge dead batteries,
the operating temperature of the alternator increases dramatically. Excess
operating temperature of the alternator for extended periods of operation can
lead to premature failure of the alternator.
If the house batteries are in a low state of charge, or dead, before
traveling it is recommended to charge the house batteries with the
inverter/charger or an auxiliary battery charger.
NOTE: Excessive loads applied to the inverter can actually
drain both the chassis and house batteries during operation.
