Symptom	Cause	Remedy
Engine starts but the crank output does not turn off	The controller is not receiving a speed signal.	1. Verify the Sensors -> Engine Speed -> Signal Source setting is set correctly. 2. Verify the Timers -> Engine Logic -> RPM Disconnect setting is set correctly. 3. Ensure the correct wiring to the controller. For magnetic pickup, Speed Sensing A and B terminals are used. For generator voltage, the AC voltage connections are used.
Sender always displayed its lowest or highest value	The sender could either be open (not connected) or shorted to ground.	Verify your connections and ensure the correct sender table is loaded.
No voltage build-up when starting set		1. Check speed 2. Check residual voltage. 3. Follow separate excitation test procedure to check generator
Unstable voltage (either on no-load or with load)		1. Check speed stability 2. Check stability setting
High voltage (either on no-load or with load)		1. Check speed. 2. Check that generator load is not capacitive (leading power factor).
Low voltage (no-load)		1. Check speed. 2. Check link 1-2 or external hand trimmer leads for continuity.
Low voltage (on-load)		1. Check speed. 2. Check UFRO setting. 3. Follow separate excitation procedure to check generator and AVR.
