DCA85USJ2 60 HZ GENERATOR • OPERATION AND PARTS MANUAL — REV. #1 (03/22/11) — PAGE 49
BATTERY
This unit is of negative ground DO NOT connect in reverse.
Always maintain battery fl uid level between the specifi ed
marks. Battery life will be shortened, if the fl uid 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 suffi ciently charged if the specifi c gravity
of the battery fl uid is 1.28 (at 68° F). If the specifi c 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 36) 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.
Figure 36. Battery Connections
CAUTION
ALWAYS disconnect the negative terminal FIRST and
reconnect negative terminal LAST.
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.
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.
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.
