6.14 SPARK MONITOR (AC CURRENT TRANSDUCER)
The spark monitor
(P/N
61034
)
evaluates the strength of the current between the ignition
transformer and igniter or igniter-injector. Wire# 140, connected to the ignition transformer (see
Figure 6-14), passes through the monitor’s orifice. If an adequate AC current is not detected in
the wire during ignition, the unit automatically shuts down. The monitor’s wires are connected to
the
I/O board’s Spark Signal terminals (see section 2.12.4).

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 e m o v e
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 (-).
