I've got a perplexing issue that I cannot seem to find the root cause for. Has anyone experienced similar symptoms?
~2000 763G - No ACS - No Bucket Positioning - Tilt and Lift spool lock solenoids clicking when machine is on and seat bar lowered. No Tilt and Lift Action
Symptoms:
~2000 763G - No ACS - No Bucket Positioning - Tilt and Lift spool lock solenoids clicking when machine is on and seat bar lowered. No Tilt and Lift Action
Symptoms:
- Tilt Spool Lock and Lift Spool Lock solenoids are clicking at a ~1second interval (click every one second)
- Both solenoids are clicking. I can disconnect one or the other and the connected one continues to click. Disconnect both and the clicking stops.
- Both pedals are locked.
- If I press pedals between clicks, every once in a while they will unlock and operate until pedal released. I cannot determine a specific pattern that works every time. It seems random.
- Clicking sound starts immediately when seat bar is lowered regardless if the machine is running or not.
- No codes
- Both solenoids have a 7.4 ohm resistance
- Seat Bar and Lift & Tilt Valve lights are on solid and no blinking when seat bar is lowered.
- Press to Operate Loader light comes on fine when pressed.
- Voltage is at 14.4V running and 12.8 not running
- Machine starts and runs fine.
- Machine will move forward and backward fine.
- I'm seeing ~12.4V pulses on positive wire of solenoids corresponding to the clicks.
- I see a PWM signal (showing a frequency) on positive wire of solenoids.
- Checked grounds on chassis near cab pivot point and seat.
- Wiggling various connectors on the harness and connectors at control module has no effect.
- Control module connections and solenoid connections are clean.
