If the engine rpm reading is incorrect or when there are
problems with disconnect or overspeed functions,
check the SW1 switch setting.

8.11.1 Introduction
Use this section for controller troubleshooting and
inteface circuit board replacement. The interface circuit
board converts the engine speed sender signal to a
2-pulse output per engine revolution needed with some
controllers.
The interface circuit board GM24832 uses an 8-position
DIP switch to provide a 2-pulse output from flywheels
with a tooth count between 15 and 255. See
Figure 8-16 for the pulse converter circuit board. See
Figure 8-17 for circuit board mounting location in the
controller.
