also can lead to abovementioned failures.
b.
Reliable fixing: generator should be correctly and reliably fixed on the
engine. The bolts should be matched with the mounting hole of
generator, and the pulley groove should share the same plane with the
driving roller groove. The generator bracket should have sufficient rigid
and strength, which otherwise may lead to damage to the generator.
c.
Check the belt tension by fingering to press down the middle part of it
with force of 150N (15kg force), it is optimal that the deflection is 10-
20mm. Belt tension should be checked once every two months. Belt
slackening may lead to generator “
slippage
”, insufficient electricity
production (that can result in lack of electricity in battery), stator
burning and damage to bearing etc.
d.
Generator should be kept away from the hot source and splashed dirt.
Splash should be avoided to enter the inside of generator, which otherwise
can damage to it. Therefore, generator should be given a good application
environment. Working temperature of generator is
－
40-93
℃
. Therefore,
its installation should be kept away from any heat source (distance of
400mm at least, or effective insulation plate should be installed), which
should be approved by the generator factory or supplier.
e.
The wire of generator should be rational, and wiring should be correct
and reliable. Each terminal of generator should be correctly connected
for fear that the harness burns or generator is damaged. Proper wire
diameter is the premise of generator capable to fully output the
generated electricity, and the base of electrical safety.
f.
Before removing the generator and welding on engine, disconnect the
battery to the generator. Generator removal, installation and repair
should be done by the professional. Check whether all insulations are
good, and immediately replace any damaged one. The positive pole of
generator should be short connected to the housing to avoid series
failure.
g.
After the engine is started, slowly increase its speed and observe
whether the charging indicator changes from ON to OFF, if not, timely
find out the cause.
h.
Check whether the negative pole of battery is grounded, which
otherwise may damage to the generator and governor.
i.
With generator running, never ado
pt “sparking” to check whether the
