Wiring Diagram
*Series 113 ignitions provide a 12-volt tack signal with two pulses per revolution. Note: Tack signal
is NOT a primary ignition function. It is a courtesy signal we are happy to provide. Due to the
variety of instruments available, we can provide only limited tack signal trouble shooting and/or
customer support.
