2 Connect a 10
Ω
resistor to the negative terminal
of a known good 9V DC battery. Connect the
other end of the resistor to a terminal on the
coil.

Note: The battery should read 9V DC or more when
measured across the terminals.

Note: Dotted lines in illustration indicate a
reversed connection as specified in
step 6
3 Set a multimeter to read DC current.
Note: 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.
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.
