Install RPM Sensor
For engines that do not provide RPM information on a data link, the RPM signal
can be supplied by the alternator, or a magnetic pickup sensor. [For TPA450-6 Ford
6.0L engines it is best to pick up the RPM from the Clean Tachometer Signal (green/
white) wire.] Refer the Wiring section. The RPM display will have to be calibrated for
correct RPM measurement. Refer to the RPM Calibration section.
Install Hourmeters
The hourmeters are built into the control module. Inputs of 12 VDC must be
provided to the control module when the generator and aerial are engaged. (Refer to
Wiring section.)
