SG1400C3 STUDIO GENERATOR • OPERATION AND PARTS MANUAL — REV. #1 (02/15/12) — PAGE 33
INSPECTION/SETUP
BATTERY
This unit is of negative ground. DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. DO NOT over fill. Battery life will be shortened if
the fluid level is not properly maintained. Add only distilled
water when replenishment is necessary.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunction. Always
keep the terminals firmly tightened. Coat 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, 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 make sure that the battery cables (Figure 17) are
properly connected to the battery terminals as shown below.
Figure 17. Battery Connections
CAUTION
ALWAYS disconnect the negative terminal FIRST and
reconnect negative terminal LAST.
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.
.
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
fatigue, 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 when connecting the battery.
CAUTION
Inadequate battery connections may cause poor
starting of the generator, and create other malfunctions.
