IMPORTANT: Make sure battery connec-
tions are the correct polarity. Electric start
generators use negative ground, 12-volt DC
starting system.
Models MGH5000CIE, MGH7000C,
MGH7000CI, and MGH10000 have an elec-
tric starter. A battery is not supplied with
generator. You must provide a 12-volt, 32-
amp-hour battery. The positive and nega-
tive battery cables are supplied with genera-
tor. You must install these cables before
mounting battery.
Always wear safety glasses when working
with battery. Make sure battery terminals
are clean. Make sure cable connections are
tight.
Always shut down engine before removing
or attaching battery cables. Always remove
the negative (–) cable first. Always attach
negative (–) cable last.

MOUNTING BATTERY TO
GENERATOR
1. Secure battery to generator by battery
hold-down system. This system consists
of the battery mounting bracket, hook
bolts, and nut (see Figure 10).
Note: Model MGH10000 battery is lo-
cated on opposite side as shown (see
Figure 11, page 9).
2. Locate the red, positive (+) battery
cable from starter solenoid. Connect it
to the positive (+) battery terminal (see
Figures 12 and 13, page 9).
3. Locate the black, negative (–) battery
cable attached to engine block. Connect
it to the negative (–) battery terminal
(see Figures 12 and 13, page 9).
4. Check battery before starting engine.
Make sure fluid levels are full. Make
sure battery is charged.
See engine owner’s manual for more
information.

CAUTION: Do not over tighten
positive terminal on starter sole-
noid. Positive terminal could ro-
tate and cut into negative termi-
nal, causing a short.
CAUTION: If you remove bat-
tery, insulate the red, positive (+)
battery cable terminal. Insulate
with electrical tape. Exposed ter-
minal may spark when generator
runs.
WARNING: Battery contains
sulfuric acid. Contact with skin
or eyes may cause severe burns.
Do not tilt generator with battery
installed. Tilting could cause bat-
tery acid to spill. Wear protective
clothing and face shield when
servicing. Keep out of children’s
reach.
• If battery acid gets on your
skin, wash with water.
• If battery acid gets in your eyes,
flush with water at least 15 min-
utes. Call a doctor at once.
Battery acid is poisonous.
• If swallowed, drink large
amounts of water or milk. Fol-
low with milk of magnesia or
vegetable oil. Call a doctor at
once.
