If you did not order the optional remote high idle, ensure that the
dummy plug (supplied) is installed on the end of the high idle cable! If
you did not receive a dummy plug, or have lost it, you NEED one!

RTU
series governors have an additional cable port
labeled “high idle” which can be used to provide a high idle switch at a remote location
on the vehicle. The PRO-38H High Idle Kit provides all the necessary components
needed to hook up this optional switch, including locking potentiometer, dpdt switch,
12V lamp indicator and 12 foot cable.
How do I activate the high idle ?
To activate the high idle, simply toggle the high idle switch to “ON”. The high idle
activated indicator light will go on and the engine will rise to the preset speed (set by
the locking potentiometer).
How do I change the high idle speed ?
Loosen the lock nut on the potentiometer. Use a small screw driver to rotate the poten-
tiometer to raise the RPM. Using the tachometer in the cab as a reference, monitor the
speed of the engine until you reach the desired speed. Once the desired RPM is
reached, tighten the lock nut to lock in the new high idle speed.
WARNING : Turn off high idle before shutting the engine off !
