3 Set a multimeter to read DC current.
The multimeter, when set to read
DC current, should be capable of
reading up to 800 mA.
4 Connect the negative lead to the other terminal
on the coil.
If testing a single-terminal coil,
connect the negative lead to the
internal metallic ring at either end
of the coil.
5 Momentarily connect the positive lead from the
multimeter to the positive terminal on the 9V DC
battery. Note and record the current reading.
6 At the battery or coil terminals, reverse the
connections. Note and record the current
reading.
Result: Both current readings are greater than
0 mA and are different by a minimum of 20%.
The coil is good.
Result: If one or both of the current readings are
0 mA, or if the two current readings do not differ
by a minimum of 20%, the coil and/or its
internal diode are faulty and the coil should be
replaced.
