TESTING PROCEDURE
PROBLEM
Machine Gives Check for proper earthing to
shock
which the machine is connected
using multimeter.
Check voltage between
Phase & Neutral
Phase & Earth
both should be equal.
Check continuity between
Neutral & Earth
If found to be short Earthing is
defective
Blown
Using multimeter check continuity
between both the ends.
Discontinuity
Check
between plug side and machine
side also check for short circuit
between wires
Not functioning
Check the capacitor with the
WARNING
multimeter in continuity mode.
DISCHARGE
The meter should first read ohms
BEFORE
and gradually the needle should
HANDLING
swing back to infinity Ohms. It
indicates a good capacitor and
any thing other than this is
defective.
Does not run
Check the winding resistance
using a multimeter between wires
BLACK & BLUE 37.6 Ohms
approx. BLACK & YELLOW 42.6
Ohms. If the resistances are not
as per the given value it could be
short or open
Does not run
Check the winding resistance
using a multimeter between wires
BLACK & BROWN 69 Ohms
approx. BLACK & WHITE 77.5
Ohms. If the resistances are not
as per the given value it could be
short or open
Subject to modification
for
proper
continuity
REMEDY
