Help please, t7 auto command range change buttons stop working this morning whilst potato harvesting, now the screen has gone black anybody no of any easy fix please.

Switch off then turn the isolator off on the cab pillar for a few minutes then re try

 

[ganderman]

Thanks del-boy, been and tried it , the screen is back , I tried your idea but it hasn't shifted it. I wondering if the isolator switch is ok because when you press it it doesn't stay down it springs back to the central position and the lights still work and ignition all work and I don't think it should !

Have you checked the big plug down behind the armrest into the back of the cab? take it off and reconnect the twist lock.

 

[ganderman]

Thanks again fergie35, been and had a look, there is two biggish oblong plugs with a locking system on them , split them and tried again but still no good ! By the way do you remember the mudguard spacers , the deal was done , but ended with a no show so still available!

Have you checked the fuse by the steps on the right hand side down near the battery

I'll bear it in mind, I had another member on here find me a set which I purchased. Thanks for the offer though.

@ganderman did you check the big square plug in the back of the screen under the bracket? worth a look. But sounds like a fuse perhaps somewhere.

That isolator which is meant too be like that you hold it down with ignition on for 16 seconds and a battery symbol will come up on the dash, keep holding it until the symbol goes and then the battery is isolated

I think you're supposed to turn the ignition of before pressing the isolator button and you don't have to hold it, it just automatically isolates after the intelliview 4 has finished saving and shuts down or at least that's how mine works

 

[blue power]

Yes never touch the isolator switch till the screw has completely shut down or you may wipe information

 

[ganderman]

Isolator works ,couldn't find fuse near the battery ours is 13 reg wobbled any plug I could find. Thinking about it the range button have been a bit temperamental you would think you had changed range but hadn't and then have to press again?

My last 3 T7.210s youv had to have the first click of ignition on, hold it down until everything shuts off then turn the ignition off

When screen went blank on our 7050, this fixed it.

Yeah they must have a few differences between models, mine T7 235 you just have to turn the ignition off and press the isolation switch for a millisecond and your done, it continues to save the data and shutdown everything by itself then isolates itself when it’s done, I was going to get a blue power t7 210 last year but changed my mind,

 

[Tassie Farmer]

Yes never touch the isolator switch till the screw has completely shut down or you may wipe information

Yeah on mine it automatically doesn’t isolate itself until it has finished saving, you don’t have to wait for it to save

There is a inline fuse in a black plastic rectangle case about 12mm wide and 40mm long they prone to corroding

 

[ganderman]

Thanks wuddy, where do I look please.

Yeah mine did that and tractor would start but no hydraulics or drive, that fuse is located under the battery cover either clipped to the front of the battery box or sitting on top of the battery, there are also fuses and relays behind the battery box but it’s unlikely that they are the problem

Battery box, usually just along the bottom nearest you when you remove the cover.
