M9540 guage problem

[Route66]

I have a 9540 and for the second time in about a month my gas gauge,temp gauge and emergency brake dash light have stopped working. is there a fuse that controls all of these gauges?

There is a small fusebox on the left side of the dash panel (on my open station model) just below the orange body parts. If it started working again, prolly not the fuse. Dirty, loose ground?

Is there one common power cable/plug for the instrument cluster, if so make sure it has a tight connection?

Sounds like a ground problem.

Not the fuse so prolly the ground... I havent had time to check it yet. Everything else works. Is there a computer chip or board that may have gone out in the dashboard? Thanks all.

Hey walnuts, if you have to take the "dash" apart, that is the orange panels (left & right) that surround the instrument cluster, let me know how you get it apart if you would please. I was trying to get mine apart the other day as there is supposedly a electrical (spare) circuit there on the right side that is for the owners use. I got the visible screws out but something was holding it at the top center.
I doubt these tractors have a chip, at least Lord I hope not!

Hey Rusty! The top of the dash is stuck on a round knob that just slips off with more pressure.

I found about six relays behind the dash. Do relay boxes ever blow? All the connections seem solid.

Still gaugeless in Turlock!!

Me & electronics = buy new stuff until it works but I would not think that the dash "workings" would use a relay, I thought that they were for heavier loads. Might be worth a call to a dealer.
Now to the round knob dodad. I've busted more plastic **** trying to get it apart than a little! This is the "orange" plastic panel that surrounds the grey smaller part that all of the guages are in, right? There is a left & right part, and the center top gets pulled towards the back or operator or up towards the sky?
My dealer could not give me an answer, and I'd hate to break something to have it mis fit and rattle forever, reminding me every time I get on the tractor. Kinda like my dent on the hood!

Pull the top of the plastic liner towards the operator. Use a flat screwdriver to pry if off if need be. If you bought it used the previous owner may have glued that fitting when replacing the dash? I didn't need a screwdriver.
All you will see behind that liner is a bunch of relays. Does someone have a **** manual for this tractor??
Another thot would be to replace the whole gauge unit with one you know that works. Borrow a neighbor's?
I'm thinking the computer chip went bad.

 

[eatwalnuts]

And I do have a 9540. Not sure why my profile says 9530...

 

[Rustyiron]

I got mine new & have the manual. I'll look at it tomorow for any guage help. I wouldn't hold my breath for any help although it does have 20 pages or so of highly detailed lawer talk on how not to be an idiot.

What did you do to fix it?

 

[JohnnyRoy]

I know this is an old thread but did any of you happen to fix the dash problem?
Looking at a used M9540 and the glow plug, fwd, pto, etc. indicators don't light up.
Fuel, tach and speedo work?
