2011 case TR320 electrical/hydraulic trouble

Case TR320 loss of hydraulic functions trouble shooting

[@darrendolman6713]

Thanks for posting this video. Those are the exact same symptoms I had and it turned out to be that exact same relay. I spent many hours looking at other wiring before I found this video.

Glad to hear I’m not the only one that had this problem

[@markbouldin6513]

I realize it's been a while but in interest of safety I have a 2012 TR320 I bought with 700 hour's on it.... About a month after purchasing the unit I inquired to the dealership and they were kind in sending me the repair bills as they'd maintained the unit for the former owner.... Some 20k in repair bills mostly electrical issues.... And sometime during the 350 hour's I've used the machine I started having some electrical/hydraulic issues.... Scary issue's like noticing some boom movement's while no hand was on either wobble stick if you catch my drift.... I'm not a mechanic and by some miracle I traced the issue(s) to the faulty main power disconnect switch and replacing the switch cured all issue's..... i wonder if some of the former owner's electrical issue's stemed from the defective switch?.... And a time or two I was restrained from accessing the inner compartment I cracked the boom cylinders hyd line's and raised the boom with another unit and I imagine most folk's thought of this but didn't have another unit on hand to lift the boom.... I wonder if the boom could be raised by applying compressed air to one or both cylinders without assing up any component's while experiencing this dillema.... Recently at auction I bought a 2018 JD331G with fire damage in hope's of salvaging.... If the JD can be brought back to life I'd probable sell the Case and keep the JD per the JD"s more user friendly design in this area and other areas.... Btw- somewhere I read folk's discussing removing the remote oil drain line and replacing the line with a plug in the plastic oil pan as per the limited clearances between the oil line and the unit's frame have been known to crack the oil pan because of debris and engine flex requiring engine removal to replace the oil pan..... A good friend of mine with too many heavy equipment unit's to list says operating these unit's new or old is like playing Russian roulette as when you turn that key or push that start button you never know what is going to happen and I imagine most would agree.......

Thanks for posting this. Almost the same problem here i had all those same codes. When inspecting it i didnt find any chaffed wires though. Something must have just been loose becuse it after wiggiling it it started working fine again.

[@BRNcontracting]

Glad I could help, figured I should post something. When I was troubleshooting there was nothing on KZbin about it.

[@matthiebert4193]

hey that's my old skidsteer, I had issues with fuse box as well. I bought that machine new in 2010 and sold in 2018. solid machine

[@BRNcontracting]

What a small world. Yeah it is a very solid machine

[@matthiebert4193]

@@BRNcontracting that's the one machine when I sold my business I regret selling.

Great. Good video. Thanks you for sharing

[@joshwebster4632]

have the same problem. the person before me had pulled out wires and i have no way of knowing the exact location. any chance you can take a photo or let me know the exact spots on the back of the fuse box that bad wire goes??

[@christiansshow2705aviation]

Nice video I love construction and diecasts Also back then in ur channel how did u make the dioramas like seriously u made it look good and this inspires me to make stop motions

[@BRNcontracting]

I quite enjoyed doing dioramas, my first dios I used everything I could pick up in my back yard. Sticks, sands and rocks, even used grass cuttings. Later on I went down to the hobby shop and found fake turf and ballast. It takes time be patient and you will do a good job.

[@christiansshow2705aviation]

@@BRNcontracting thanks for the tip I really want to make stop motions I ask other youtubers but they don’t respond also can u send me some links where I can get the stuff?

[@robertware1073]

How did you raise the bucket with the codes locking you out?

[@jonnyone24]

I have a 2014 case skid steer it was running at low speed, ran into an unseen pile of dirt in the engine, bog down and shut off now it will not restart. What do you think the issue is thank you in advance.

[@BRNcontracting]

I'm not a mechanic by any means, but if you have no lights or alarms I would try looking for a ground issue on your ignition side

[@jeffs2780]

Did you ever have a problem with the attach and detach of attachments I have a sv300 that won’t allow me to detach current attachment? I found a few wires with nicks in them near those fuse boxes but no blown fuses or any relays that look melted like yours but wondering if I have a bad relay not allowing the unlock/lock button to operate properly any help would be greatly appreciated

[@BRNcontracting]

Sorry man never had an issue like that

[@jeffs2780]

@@BRNcontracting thanks I appreciate the quick reply! Yeah unfortunately can’t seem to figure it out and not much info online about it. Just figured I’d see if you had same issue. Thanks again man

[@WichhartAcres]

@@jeffs2780 I am having the same issue with my case sr250! Can't get the actuator to release the bucket to work. When I toggle on the unlock button I noticed that the light does not turn on. Do you see that also? I found the fuse that is tied to the switch and saw that it was popped. I put a new fuse in and the second I turned the skid on it popped the new fuse. Please let me know if you find out what is going on! I will do the same for you!

[@jeffs2780]

@@WichhartAcres yes also don’t have the light on the unlock button but don’t seem to have any blown fuses either have checked all fuses in both fuse boxes and haven’t found one blown. Will do thanks for the reply

[@joewhite2396]

How did you get the lift arms up?

[@BRNcontracting]

My machine would run. It would just throw codes

[@BRNcontracting]

But you really don't have to lift the arms to get at the fuse box, you can access it with the cab down

[@K9Stryker]

@@BRNcontracting My machine is throwing the codes 5511, 1904, etc. which causes my hydraulics not to work at all. I checked the fuse box and tested every fuse and everything seems OK in there. Even tested the relays. The next step was going to be checking the wires under the cab for chafing but I can't raise the cab without lifting the arms. Any ideas? Thanks.
