BASIC CONTROLLER
Page 12 of 12
If a safety switch is present, insure
that it is receiving power and in
good working order.
Check that the wire connected to pin
9 at the controller is not cut.
COIL FAULT
Check the following items:
Check that the wires from pins 3 & 4
are neither cut or grounded, nor
connected together, thus creating a
dead short.
Check that the voltage stamped on
the side of the coil (either 12 or 24
volts) matches that of the
equipments voltage supply.
The
stampings on the side of the coil
MUST match the equipments
voltage source.
Make sure pin 3 & 4 wires are
pushed all of the way into the
connector at the back of the
controller.
Use an Ohm Meter and measure
the resistance between the two coil
wires at the coil.
The two wires at
the controller may need to be cut in
order to take this measurement.
The Ohm readings should be as
follows:
12 volt coil = 6.4 ohms +/- 1 ohm
24 volt coil = 29.3 ohms +/- 1 ohm
RPM TOO HIGH, while
disengaging
If the actual speed of the engine is well
below the minimum 1200 rpm speed that
the controller is requiring, yet the “RPM
TOO HIGH” symbol is illuminated when the
“Engage/Disengage Button” is pressed,
then refer to the Troubleshooting section
titled, “Engine Speed Detected” LED Fault.
Clutch Disengages Unexpectedly
The controller will automatically disengage
the clutch for two reasons.
First, if there is a pressure fault while the
clutch is engaged.
See “Controller
Functions” section.
Second, if the controller loses a signal from
the engine speed pickup.
See the
Troubleshooting section titled,
“Engine
Speed Detected” LED Fault
”.
