SYSTEM DESCRIPTION
COMPONENT PARTS
Circuit BreakerINFOID:0000000006275745
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of t
he thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise shar ply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

Harness ConnectorINFOID:0000000006275747
HARNESS CONNECTOR (TAB-LOCKING TYPE)
 The tab-locking type connectors help prevent accidental looseness or disconnection.
 The tab-locking type connectors are disconnected by pushi ng or lifting the locking tab(s). Refer to the figure
below.
CAUTION:
Never pull the harness or wires when disconnecting the connector.

< BASIC INSPECTION >
BATTERY INSPECTION
 Remove the cell plug using a suitable tool.
 Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Use the chart below to correct your hydrometer reading accord- ing to electrolyte temperature.
