Does anyone have any wiring information for a 35, 3 cylinder diesel.
Just the Starter / Preheat and supply on the back of the start switch and where they go etc.
My manual shows ...
(Blue/White) -> Neutral Switch (White/Red) -> Starter
(Brown/Green) -> Thermostart
(Brown/White) -> Ammeter -> (Brown) -> Starter -> Battery

But my Tractor has Brown, White/Blue, Green/Brown.

I assumed the Brown (Biggest wire) was the same as the Brown/White ... but ... metering it out it makes no sense.
Perhaps the Control Box / Dynamo are affecting my resitance checks.

It was getting late but at least it now has a start switch ready to fit, an exhaust and air filter pre-cleaner so its starting to take shape.

Also when i cleaned the Meter it only has 2000 hrs on it (i mis-read it as 8000) :)

Any information on the above wiring much appreciated.

Thanks JJ.
i will get back out in the daylight this time and meter it out. Looks like the manual i have is for earlier 35's as it shows 2 6-volt batteries.
Are the workshop manuals available as a pdf online?

Well amazingly with a fresh battery, some fuel it started real easy. Ran it breifly, oil pressure looks spot on. now its time to change fluids & look at brakes etc.
I left the Thermostart disconnected as it appears to be dead short.

So some more questions ...

Does anyone know what the thermostart consists of? Is it a valve / heater, just a heater? If its just a heater what controls the fuel feed?
Where does the oil for the hydraulics go & is there a dip stick. I have located the engine oil and gearbox / diff oil dipsticks so far.
Should the Quandrant level operate the 3 point (with the engine running) or do i have to engage the pto?

Thanks in advance.

Jon (very happy its a runner)

Jon, i believe workshop manuals are still available from your AGCO/MF dealer.
When the Thermostart is activated it meters a small amount of fuel from a small holding cylinder in the "leak off" return line from the injector pump, this is then ignited by the heating element and drawn into the manifold, your thermostart sounds like it is likely burnt out and needs replacing.
The hydraulic filler is located to the left of the main gear shifter, a large plug, the dip stick is by your right heel when sitting on tractor, this is a common reservoir for the hyd/trans/diff.
If your 35 has the dual clutch the 3pt hitch will operate independently of the PTO when the clutch pedal is released.

Finally got back on the case of the 35...
Its has dual clutch and the hydraulics work (not tested under load yet)
The Dynamo is totally shot (looks like it was running full of mud or water or a combination of both!)
I have located another tractor (ford something) to salvage some bits off, not sure if i will take the dynamo from that or modify the bracket to fit an alternator & convert to negative earth), i will try and get a picture of the ford to identify it, it looks more modern but has a dynamo so i guess its fairly old.
Is there a way of upgrading the 35 to power steering? I have seen some kits that fit externally but how did the 35 supplied with power steering work?
Next is to charge the battery up, change the tyres and then give it a proper run & see what happens :)

Unless you are able to locate a donor tractor with all the PAS parts intact retrofitting the original system would be cost prohibitive, thats if you can even find them, i don't think they are still available from MF and if they were it would probably be cheaper to buy another tractor with PS, the transmission top would have to be changed to one with the PS gear cast into it as would the gears and steering shafts, then the pump fitted to the Perkins engine and all the lines. If you feel you really have to have PS some type of aftermarket add-on would be the way to go.
