Yamaha Generator Theory & Diagnostics Guide
Resistor and Non-Resistor Spark Plugs
Resistor type spark plugs are used in all Yamaha
generators. Do not use non-resistor type spark
plugs. Refer the Owner’s Manual or Service Manual
for complete information.
Neutral Ground and Floating Ground (Open
Ground – False )
Neutral Ground (also called “neutral bond”) means
earth ground and neutral are bonded together
(wired together). This creates less chance of electro-
cution by providing two paths for electricity to travel
in the event of a short.
Floating Ground means that earth ground and neu-
tral are NOT bonded together. All Yamaha Inverters
use a “floating ground” grounding method.
Devices that require a Neutral Ground (bonded neu-
tral) will not work correctly when plugged into a float-
ing ground generator - this is because the device
can not locate an earth ground presence.
Ground Fault Circuit Interrupter (GFCI)
A GFCI protected outlet interrupts power delivery
when a fault or short to ground is detected to pre-
vent electrocution. It is a device that interrupts the
power flowing through a GFCI receptacle when a
proper ground is not present or if/when a short
occurs. All Yamaha Industrial series generators (YG
models) are equipped with GFCI protected outlets.
ExTENSION CORD GUIDELINES
A proper extension cord must always be used. If a
cord is not heavy enough for the load it must carry,
it could burn or there could be a severe reduction in
power available at the end of the cord.
The following chart shows the minimum extension
cord wire size for the amount of the expected load.
Note that the wire size increases with the length of
the cord as the anticipated load increases. Light-
gauge cords can be easily damaged. Practical con-
siderations suggest that small-size cords (20 gauge
or smaller) be avoided.
