Case 500 Stx 700 display questions

[danny W1M]

Jag we just had some problems with our 4wd (of the same series) too.

Eventually the " SCR warning " came up. Check out page 4-19 in your manual. The controller needed to be replaced (located in the front right fender), apparently they quit working, ours was replaced with only 2 weeks left on warranty.

Could be crystals in the line from the controller to the injector(under engine hood).

DEF may have crystalized over winter in your DEF supply tank.

Was loosing power and the warning eventually came up in the corner post display.

We also had a EHR fault, was total it's likely the in cab lever the you use to move the hydraulics. Something they have to do as it will need programing. We just don't use that lever as there are 5 others.

Redhead made a visit here too, ouch!

Clean the ground cable from the battery to the frame and also clean the ground on rh front of engine block.

Agree with checking all grounds, had a problem with combine in the past ,took awhile to find it .It was a bad ground in wiring harness mid-frame. Was always putting error codes up.

Thanks for all the replies

Redhead out again this morning hopefully they can find the problem

Scared to see the service bill on a long weekend

Jag, Did redhead get er figured out?

Replace the two terminators...was having similar issues and it cured it.

After 3 service calls it looks like it is working Ok

2 service calls on the long weekend

Scared to see the invoice

There is some BUS CAN communication wires that are in a wiring harness that comes out of the bottom of the cab among the several wiring harnesses under the cab.
They were rubbing on a hydraulic line under the cab
They were not rubbed right through but just the contact with the hydraulic line was enough to cause the trouble


When service came out the first 2 times they could not get codes to show up as it was temporarily working at the time


The 3rd time they came out the codes showed up.



It was a pretty frustrating couple of weeks but things are working good the past few days since we got it fixed.

I bet in total we could have seeded 600-800 acres more than we have to date if we did not have this trouble.


Most of the time we try not to work on Sundays but we have this year to make up for all the time we lost with the tractor

It's raining now so will be a day or 2 till we get back at it.
Did not rain much so far a couple of mm but looks like more on the way.

Electrical issues are the most frustrating
