Battery Cable Installation

ALWAYS make sure that the battery cables (Figure 13) are properly connected to the battery terminals as shown below.

CAUTION

ALWAYS disconnect the negative terminal FIRST and reconnect negative terminal LAST.

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.

.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.
