TSLM - M601 Operational & Install Manual
Ignition Circuit
The ignition circuit consists of either one or two exciter (igniter) boxes that generates pulses to the
spark plugs. The TSLM is capable of powering two exciter boxes with power requirements of up to
5 Amp each and also allow for independent ignition checking through a toggle switch. The next
figure shows the wiring diagram for a single exciter ignition circuit. The single exciter is able to
drive both spark-plugs.

When using two separate exciter (igniter) boxes, each one only capable of driving one spark-plug,
the ignition circuit in the following figure may be used instead…
