I suggest you check your control lock out it may be as simple as switch issue.
Kind regards

another thing that is it doing is it will flash L F back and forth sometimes it will stay on S but then will switch back to L F

Attached is some information made for a 130 machine if yours looks different give some photo's back and we will try to help out. Hyundai refer to the control lock out as "safety valve" we do not use that term.
Kind regards

I just ran it this morning, everything works great as soon as I lift safety lever beside seat and when I put it back down I have no controls and no track movement

It would appear we are in the right place for the problem, one of the solenoids have been replaced ?
I will try and track down some illustrations to help.

My photo is a little different, please see attached, the valve should be equipped with a mechanical override I can see that with the valves other than that which appears to be new.

Compliments on the photo.s first class, to your problem I am 95% sure according to to your post that we have located the offending part. You will need to go to an automotive outlet and pick up a diode, please see attached and come back with a result. I suspect you will find that the diode has not been included in that new solenoid.(Where in the world are you?)
Kind regards

hello, I am located in Ontario canada!

Well everything seems to have worked out I got a new one from dealer and that seems to have fixed it hopefully for good!

Now that its all working I thought maybe my wheel travel motor trouble was from that but it seems to still be there!

I don't know if I have to start a new thread or not but my left side track works fine in reverse but really slow forward right side track works perfectly fine what should I start with checking into that? thanks Taylor

Good day Taylor
The most probable cause for that dilemma is the shock valve leaking. I suggest you switch the shock valves and see if the issue transfers from forwards to reverse.

Attached are some checks to make so we can be sure the issue is of a hydraulic nature.
If the checks come up negative switch the main lines and see if the issue cross's over, it remains the same we have a motor issue if it crosses we have an issue post motor
Kind regards

I neglected to mention both main lines are open to tank fluid loss, a possibility. Be sure to vent the tank first,
Kind regards

Hey there,
Well I seem to have got it fixed the one plunger in the pedal for forward was stuck and wouldn’t let it go down simple fix! I really appreciate all your help through this, I am curious to know where is the best place to buy manuals I want to check all the wiring this harness underneath engine was torn apart and I want to make sure it’s all together correctly! Thanks Taylor3CC7C4D1-4A62-43DB-B3E0-7F504A86CE21.jpeg
