Possible Cause:
1. Dirty Tach Probe
2. Faulty Tach Probe
3. Incorrect settings
4. Engine not returning to full rated RPM’s
5. Clutch or drive belts slipping
Solution:
1. Remove tach probe and clean any debris from its end.
To install, turn the probe in till it touches the flywheel teeth
and then back it out 3/4 of a turn.
(Tach probe located on top of the flywheel housing)
2. With the engine shut down and the ignition switch off,
check the draw at the probe by using a meter capable of
reading ohms. There should be a reading of 140 ohms, if
not then the probe needs to be replaced. To install, turn
the probe in until it touches the flywheel teeth and then
back it out 3/4 of a turn.
3. Follow the procedures for changing the settings of the
“Autofeed Plus” system to make sure that they are
correct.
4. Check engine throttle setting to make sure it is where
it should be. “Autofeed Plus” system high RPM setting is
too close to actual engine high RPM’s. There should be
about a 200 RPM difference.
5. The “Autofeed Plus” system works with the engine
speed so if the clutch or belts are slipping allowing the
Cutterhead to slow down and the engine speed doesn’t,
than the “Autofeed Plus” will not stop. If this happens you
will need to adjust or replace the belts or clutch.
**With PT Tech Clutches 395 HP and above use a PPR value of 113
