Valve Coils
How to Test a Coil
A properly functioning coil provides an
electromotive force which operates the solenoid
valve. Critical to normal operation is continuity
within the coil that provides this force field.
Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
1
Tag and disconnect the wiring from the coil to
be tested.
2
Test the coil resistance.
Result: The resistance should be within
specification, plus or minus 30%.
Result: If the resistance is not within
specification, plus or minus 30%, replace the
coil.

How t o T est a Coil Di ode
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 10Ω 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.
