A
choke ballast is a highly functional device which is mainly used for the
glowing of light fixtures. Traditional lighting that use the long bulbs have
chokes in it. Troubleshooting a ballast is quite an easy task. For that, all
you need are some tools and a beginner’s understanding of the working of high
voltage transformer.
Step
1 - Cut the Electrical Power From the Light
Before
beginning, it is important to turn off the power running to the light. After
turning off, wait for sometime in order to allow any kind of stored current
within the ballast spread in the lighting circuit.
Step
2 - Remove the Cover and Observe the Ballast
With
the help of a screwdriver, you can remove the cover that hides the ballast, and
observe it. If you see some oil leaking from it, replacement is required.
Leaking oil is a symbol that the internal seal has been broken by too much
heat.
Step
3 - Test the Ballast
In
order to figure out other problems, testing the ballast is important. Using
your multimeter you can test the high voltage. Blue or yellow are the power
wires and white ones are the neutral wire.
In
case your Electronic Choke Ballast is working properly, a continuous circuit
will be displayed. If it does not show the same it means it requires
replacement. If all the wire pairs test positive, you can then continue to
check the low voltage side of the choke ballast.
Step
4 - Test the Low Voltage Side
For
testing the low voltage side, you can start by taking off the nuts from the black
and white wire that arise from the power feed side of the ballast.
If
on both the high and low voltage your ballast functions correctly, you should
check the wire connections. At times one wire can become loose and cause
malfunctioning.
