What model 185 do you have, the 3 cyl or 4 cyl version? Do any lights or alarms on the instrument panel come on when the pedals lock. Is there any fault codes displayed? Does the parking brake apply when the pedals lock? Do you notice it more in rough terrain? The voltage is probably not the issue.
L185 is the model. Everything else is normal,no alarms,no codes, just going down the drive and they may stop. Solenoids chatter and foot pedals lock up. Removed the solenoid for bucket and connected to 12 volt and it worked fine.This is a four cylinder machine.Thought it was the solenoid for the bucket and removed it then boom solenoid started doing same thing.Shut machine off and restart and will work or not for short time.What model 185 do you have, the 3 cyl or 4 cyl version?

One possible cause would be the seat wiring harness. The way these machines were originally designed was for the power to go to the seat switch and then to the seat belt via the seat switch. What happened is when traveling down a drive or over rough terrain the operator would temporarally lift enough weight off the seat to cut the power to the seat belt and instrument panel and lock the foot pedals and in some cases lock the parking brake depending on how long the power was cut off. The work around was to rewire the plug at the seat switch so power was sent independently to both the seat switch and seat belt. A new harness is now available that is wired this way.L185 is the model. Everything else is normal,no alarms,no codes, just going down the drive and they may stop.

You might take a look at the seat switch to see if it is in the right position. Also take a look at the wires going into the wire connector. Give them a tug to make sure you do not have a broken wire at the connector. This was a common issue at one time but so much on your age machine.
You might also want to check the grounds at the left rear cab pillar. You will need to remove the left fender. The grounds are located right below where the cab bolts down to the yellow frame.
There are also a number of harness connectors in this area you might want to check them to see if any of the pins or sockets are slightly pushed out of position.
When this happens does the activate button light up like you have to push it to enable the hydraulics and release the parking brake?
Will it always work on restart and pressing the enable button?
Will check out the grounds. Have not noticed any lights coming on when it does this like seat belt etc. Park brake does not come on when this happens.First it was just the solenoid for the bucket then later that day the boom started doing it also. No it does not always work after re-start or might just work for a few seconds. Will check out wiring as you suggested and let you know. Knowone can tell me for sure if there should be 12 volts to these solenoids or something less than that. Thanks for your help so far.One possible cause would be the seat wiring harness.

Anything over 10V should activate the solenoids. If you had one solenoid still plugged into the circuit you will definitely have less then 12V present at the other solenoid. Both solenoids share the same power source with it being split between the two near the control valve.Will check out the grounds.

I was uncertain if both solenoids would quit at the same time or it was one or the other but not both. Since the bucket solenoid quit first I would unplug it and drive and operate the loader and see if the boom solenoid also quits working. If the boom solenoid quits working I would disconnect the boom solenoid and reconnect the bucket solenoid and again operate the loader. One bad solenoid will sometimes only lock one pedal and at other times it will lock both.
Have you checked if you had power at the connector when the pedals are locked? Have you tried pressing the enable button on the instrument panel to see if that would free the pedals? When the pedals are not working on restart what did you do to get the pedals to work?
Looks like my problem is actually with the solenoid for the boom.When plugged in it draws down voltage and causing bucket solenoid to not work properly.Have ordered one and should be here today or tomorrow.
