How to Test a Coil Diode
Properly functioning coil diodes protect the
electrical circuit by suppressing voltage spikes.
Voltage spikes naturally occur within a function
circuit following the interruption of electrical current
to a coil. Faulty diodes can fail to protect the
electrical system, resulting in a tripped circuit
breaker or component damage.
Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
1
Test the coil for resistance. Refer to Repair
Procedure,
How to Test a Coil
.
2
Connect a 10W 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.
Resistor 10Ω
Genie part number 27287
Note: The battery should read 9V DC or more when
measured across the terminals.
1 multimeter
2 9v DC battery
3
10Ω resistor
4 coil
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.
