can someone tell me how to test/measure an inductor on a power supply
circuit board. can it be done in circuit with a VOM?
TIA

Peter said:My own inductance measuring (though for smaller coils) is with an RF
oscillator and
a frequency counter (0-4 MHz built into a multimeter). The inductance is
calculated
from the frequency. Cost about $10-20 to build.
John said:Louie, that is about as much as I can help you
with your inductor problem. If you tell us what
you are building or repairing then maybe Phil
or some other members of the gang will chip in
with some suggestions.

card.

as for the power supply, i'm going to set up an artificial load on the
output and put a low voltage on the input and see what i can come up
with. problem is, there's one unknown variable that i can't figure.
the supply has six output pins: ground, one regulated output that goes
back to the control curcuit, three more outputs, and one input comming
back from the external load that also goes to the control circuit. it
may be that without that external input it just won't do anything.
do you know why there would be a signal comming bck from the TV to the
control?
