Battery Cable Installation
ALWAYS be sure the battery cables (Figure 39) are
properly connected to the battery terminals as shown below.
The red cable is connected to the positive terminal of the
battery, and the black cable is connected to the negative
terminal of the battery.
CAUTION
ALWAYS disconnect the negative terminal FIRST and
reconnect the negative terminal LAST.
POSITIVE
Figure 39. Battery Connections
When connecting the battery do the following:
1. NEVER connect the battery cables to the battery
terminals while the Auto Start/Stop switch is in either
the AUTO or MANUAL position. ALWAYS make sure
that this switch is in the OFF/RESET position when
connecting the battery.
2. Place a small amount of battery terminal treatment
compound around both battery terminals. This will
ensure a good connection and will help prevent
corrosion around the battery terminals.
NOTICE
If the battery cables are connected incorrectly, electrical
damage to the generator will occur. Pay close attention
to the polarity of the battery when connecting.
CAUTION
Inadequate battery connections may cause poor
starting of the generator or other malfunctions.

INSPECTION/SETUP
ALTERNATOR
The polarity of the alternator is negative grounding type.
When an inverted circuit connection takes place the circuit
will be in short circuit instantaneously resulting in alternator
failure.
DO NOT put water directly on the alternator. Entry of water
into the alternator can cause corrosion and damage the
alternator.
WIRING
Inspect the entire generator for bad or worn electrical wiring
or connections. If any wiring or connections are exposed
(insulation missing), replace wiring immediately.
PIPING AND HOSE CONNECTIONS
Inspect all piping, oil hose, and fuel hose connections for
wear and tightness. Tighten all hose clamps and check
hoses for leaks.
If any hose (fuel or oil) lines are defective replace them
immediately.
