Burner Components
Ignition Coil
The diesel burner’s ignition coil produces a high voltage ignition
spark (approximately 8000 volts), which is released across the
metal tips on the ignition electrodes during the initial diesel
burner start up.
Use extreme care when testing the ignition coil, as a
High Voltage Shock may result�
Component Test:
1. Remove the four ignition coil screws that secure the ignition
coil in place.
2. Disconnect the ignition coil’s black (+) and brown (-) wires
from the C-plug harness’ yellow (+) and brown (-) wires.
3. Connect the ignition coil wires directly to a 12V DC power
supply (black + wire to + lead and brown - wire to - lead).
4. Turn the power supply ON and watch for a spark to appear
across the metal tips of the ignition electrodes. If a spark
does not appear, the ignition coil must be replaced.
NOTE: In order to perform the following procedures, it is
necessary to detach and reattach the diesel burner head.
Be sure to review the detaching/reattaching procedure
starting on Page 47.
NOTE: Some ignition coils are intermittent and will need to
be tested numerously. If the ignition coil tests well, and it
still will not operate, it is possible there is an issue with the
Reporter.
Replacement Procedure:
1. Disconnect the ignition cables from the ignition electrodes.
Remove the four ignition coil screws that secure the
ignition coil to the protection cap. Lift the ignition coil and
disconnect its wires from the C-plug harness wires, prior to
removing.
2. Connect the new ignition coil’s black (+) and brown (-)
wires to the C-plug harness’ yellow (+) and brown (-) wires.
Attach the ignition coil to the protection cap with the four
ignition coil screws, then reconnect the ignition cables to
the ignition electrodes.
3. Follow the instructions for reattaching the diesel burner
and test for proper operation.
Before replacing the ignition coil, verify the electrodes are not
cracked or broken, and they are adjusted properly. Ensure the
electrode boots are securely holding the electrodes in place and
that they are not broken inside the ignition coil wires�

NOTE:
If the new ignition coil does not function, check wire
connections and ensure they are properly connected and
the electrodes are properly adjusted.
