Battery
This unit is of negative ground DO NOT connect in reverse. Always maintain battery fluid level between the specified marks. Battery life will be shortened, if the fluid level are not properly maintained. Add only distilled water when replenishment is necessary.
DO NOT over fill. Check to see whether the battery cables are loose. Poor contact may result in poor starting or malfunctions. Always keep the terminals firmly tightened. Coating the terminals with an approved battery terminal treatment compound. Replace battery with only recommended type battery.
The battery is sufficiently charged if the specific gravity of the battery fluid is 1.28 (at 68° F). If the specific gravity should fall to 1.245 or lower, it indicates that the battery is dead and needs to be recharged or replaced.
Before charging the battery with an external electric source, be sure to disconnect the battery cables.
Battery Cable Installation
ALWAYS be sure the battery cables (Figure 35) 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 negative terminal LAST.
Figure 35. Battery Connections
When connecting battery do the following:
1.NEVER connect the battery cables to the battery terminals when the MPEC Control Switch is in either the MANUAL position. ALWAYS make sure that the MPEC Control 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 cable is connected incorrectly, electrical damage to the generator will occur. Pay close attention to the polarity of the battery 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 be in short circuit instantaneously resulting the 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 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.
