WARNING
High voltage is present. Do not touch ignition coil or air heater assembly while
performing test. Failure to comply may result in injury to personnel.
CAUTION
Do not apply voltage to ignition coil unless coil is connected to air heater assembly.
Ground coil and air heater assembly. Connect positive lead to pin (Figure 3, Item A)
and negative lead to pin (Figure 3, Item B) or damage to coil will result.
c.
Connect a 24 V dc power source to power input side of ignition coil (Figure 3, Item 4). Observe electric
arc between fuel igniter (Figure 3, Item 21) and wire (Figure 3, Item 20). A steady or intermittent
(about 10 pulses a second) arc with a popping noise indicates a good coil and igniter.
d.
Disconnect power source and then disconnect leads from coil (Figure 3, Item 4). Remove high tension
lead (Figure 3, Item 23) from coil and fuel igniter (Figure 3, Item 21).
e.
Disconnect air heater assembly (Figure 3, Item 22) and ignition coil (Figure 3, Item 4) from common
ground (Figure 3, Item 19).
