A short red wire with bullet connectors on each end and a 20-ohm resistor is supplied with this
Ignition Control. This jumper wire may need to be installed in series on the small red ignition (on/
off) wire when the battery input voltage is over 14 volts.
When the optional Launch Control, PN 7551, or Hand Held Monitor, PN 7550, are left connected to
the Programmable 7-Series Ignition Control and the ignition receives over 14 volts, the unit may
shut down. This resistor jumper wire will prevent that from occurring by lowering the input voltage.
This will not affect the output of the ignition (which gets its supply voltage directly from the battery).
MSD has already incorporated this change in the ignitions. If your ignition has an R1 or R2
stamp on the end panel, you will not need the Resistor wiring. Also, if you are not using the
Hand Held Monitor or one of the Launch Controls, the resistor jumper wire is not required.
