I assume you're talking about a New Holland machine. You may get better answers if you post your question in that section of the forum. I'm going to move this to that section.
I should have specified 1997 New Holland 665 turbo. It is only the right pedal locked in place. when I attempt to rock the pedal it seems to jiggle the linkage in the right operator handle. Would the seat interlock issue only disable one pedal?
Remove the metal cover between your feet and the control valves are there.
There is a lockout solenoid in each one. Check for current to the right one and if there is current there the solenoid itself must be the problem.
I currently have the seat out to check the seat sensor. I suppose the seat should be reinatalled to check the solenoid. One other question, the seat belt and e-brake lights are flashing when running. Is this normal? Another problem today, err2 is which seems to be the fuel solenoid issue. The machine wont start and I am wondering if these are related.
Look at your service/run switch and make sure it is set to the run position. The only reason you can move your left pedal is the pin in the solenoid is stuck. The engine should not start if the seat belt light does not go out unless the switch is in the service position. If the switch is in the run position then as you sit in the seat watch the instrument panel and see if it lights up. If it lights up fasten the seat belt and see if the seat belt light goes out. If those lights are out the engine should start and the hydraulics should work. If the lights do not come on when you sit in the seat and the switch is in the run position then check the 5A fuse in the engine compartment fuse panel. You can also check for power at the seat switch. There should always be 12V at the seat switch. When you sit in the seat it sends 12V to the seat belt connector and also to the instrument panel to activate the self check. If the seat belt switch is OK then when the seat belt is fastened the power goes to instrument panel to put out the seat belt light. I'm betting you have the switch in the service position. Once you get this problem taken care of you should remove the left foot pedal solenoid and free up the pin in the end of the solenoid. It's an accident waiting to happen.
Still trying to fix a stuck right pedal on my New Holland 665LX. I replaced the lockout solenoid and even the new one locks the pedal. The pedal was free when I removed the old solenoid. I suspect this is an electrical issue. The seat light and emergency brake lights both flash as the machine is running, I also have an ERR02 message that should be a fuel solenoid issue. Could these all be related?
You need to do your troubleshooting systematically. Throwing money at the problem with out some idea where to look will get quite expensive.
First. Is service/run switch flipped to the run position?
If no, switch to run
If yes, as you sit in the seat watch the instrument panel. Do all the lights come on?
If no, you have no power to the instrument panel from the seat switch.
If yes, fasten the seat belt. Does the seat belt light go out?
If no, you have no power to the instrument panel from the seat belt.
If yes, the safety interlock system is working.
If the problem is with one of the above steps, repost what you have found and I will walk you through where to look.
If you made it this far, then start the engine. If the seat belt light is flashing unfasten and refasten the seat belt. Some instrument panels will reset when the engine is started and you will need to refasten the seat belt.
Your err message could be related in that your instrument panel has a high probability of corrosion affecting its operation. If you have a friend who has a lx or ls skid loader, ask if you can plug their instrument panel into your loader. This is the easiest way of knowing if the problem is in the instrument panel. As long as you disconnect the negative battery cable when doing the switch no damage will be caused to either panel. Their replacement panel will not fit up into the opening on your loader, just plug it in and let it hang and check the operation of the pedals following the instructions above. New Holland has a special panel for the early LX models that had instrument panels with silver trim.
Now for the pedal that is working. That pedal should not be working and needs to be repaired. Just remove the solenoid of that pedal and spray some penetrating oil around the pin on the bottom and tap it to free up that pin so it will engage the valve spool when it is supposed to. If the pin is free then look into the spool through the opening the solenoid screws into, somethimes dirt can enter and pack it the groove. Clean out the groove. You have a real safety issue there.
Disconnect the solenoid for the pedal that is working. I don't think this is the problem but it is easy to check. Since you bought a new solenoid you know it should be good, just leave it plugged in. You need to have one solenoid connected for the sytem to work. See if the system works with the one solenoid disconnected.
Mike, I changed one broken seat sensor and still same problem. The instrument panel lights up normally. The seat belt and e- brake are still blinking and the right pedal is stilll locked out. Seems likme the seat is not speaking to the instument panel.
One other note on my 665 skid steer pedal locked. I can start and operate this machine without sitting in the seat or fastening the seatbelt. There must be an electrical situation.
Sounds like the service/run switch is in the service position. The switch is in front of the cab fuse panel by the right side of your head. Have you tried flipping the switch?
Let's take this one step at a time. Have the key OFF. Sit in the seat while watching the lights if the lights light up the seat belt circuit is intact.
If the lights do not come on, then turn the key on, if they come on then, the service run switch is in the wrong position, or the service run switch is defective, or you have a fuse blown in the engine compartment fuse panel.
Let me know what you find and we will continue from your results.
Just a thought. Open the top engine compartment panel and look at the back of the seat. You should see the seat wiring harness. Make sure it is plugged into the main harness and has not been bypassed at the main harness.
Thanks Mike, I have checked the main harness for the seat, it seems properly connected.
I will try flipping the switch the other way. I believe it is in the run position. At times during this process, I have flipped the switch forward and the machine has stopped running. At the moment, the lights do not come on unless the key is turned. You may be onto soemthing with this switch. Thanks, I will reply tomorrow as I am on the east coast.
