6.14 SPARK MONITOR (AC CURRENT TRANSDUCER)
The spark monitor
(P/N
61034
)
evaluates the strength of the current between the ignition
transformer (P/N
65085
) and igniter or igniter-injector (see Figure 6.14-2).

The
monitor’s wires are connected to the
I/O b
oard’s Spark Signal terminals (see Section
2.12.4).
Wire# 140 is connected to the ignition transformer. It passes through the spark
monitor’s
orifice. If an adequate AC current is not detected in the wire during ignition, the unit automatically
shuts down.
Figure 6.14-2: Spark Detector Sensor Wiring
If the spark monitor needs to be replaced, open the
monitor’s orifice by pulling on the tab at
the side, remove Wire# 140, disconnect the
monitor’s wires are from the I/O board, r em o ve
the old monitor from its position, i n s t a l l a new monitor in its place, r o u t e wire# 140
through the new sensor orifice, and connect the wires to the I/O board
’s Spark Signal
terminals, red wire to the positive (+) terminal and black to negative (-).
