INSPECTION/SETUP
Battery Cable Installation
ALWAYS make sure that the battery cables (Figure 13) are
properly connected to the battery terminals as shown below.
Figure 13. Battery Connections
When connecting the battery do the following:
1. 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.
2. Connect the red cable to the positive terminal of the
battery and the black cable to the negative terminal
of the battery.
.
CAUTION
ALWAYS disconnect the negative terminal FIRST and
reconnect negative terminal LAST.
NOTICE
If the battery cable is connected incorrectly, electrical
damage to the generator will occur. Pay close attention
to the polarity when connecting the battery.
CAUTION
Inadequate battery connections may cause poor
starting of the generator, and create other malfunctions.
ALTERNATOR
The polarity of the alternator is negative grounding type.
When an inverted circuit connection takes place, the circuit
will short instantaneously resulting in alternator failure.
DO NOT put water directly on the alternator. Water in the
alternator can cause corrosion and damage.
WIRING
Inspect the generator for bad, worn electrical wiring or
connections. If any wiring or connections are exposed
(insulation missing), replace wiring immediately.
PIPING AND HOSE CONNECTION
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.
