Massey Ferguson 3065 Electrical Problems!

[Westside]

Good afternoon! Since pressure washing my tractor, which is the 16 speed 2wd '94 version, last week, I have lost the hi/low, splitter, Diff Lock and PTO. To start with, I had the LEDs for turtle and hare flash at the same time, now I don't have the LEDs iiluminate for splitter or Hi/Low.
I took the cover off the electrical connectors on the rh side of cab and blew out/ cleaned the connectors plus cleaned the battery terminals and checked the alternator connections.
With my fingers crossed, I tried the tractor again and now I've lost the three point linkage as well! This has been a right pain as everything worked perfectly on the tractor before..... Can any of you Massey men give me some suggestions as to what to try now ....
TIA

From memory there are a lot of connectors under the cab by the rhs steps, may have got water in here? Or perhaps the connectors on the side of the transmission?

 

[Cjm]

There are several main fuses underneath the bonnet on the rhs near the front. Up high in front of the rad. Have a look at those...

 

[masseybreaker]

start at the begining check the alternator is charging properly NOT just putting the charge light out it could be a slack fan belt . it is most likely that because you have lost everything check that first

never wash a tractor

never wash a tractor

Not with a pressure washer anyway

Very good point washed the t6 then thought let's clean the Massey too ... regretting it now!!

Had issues with my 3075 one frosty day took few days to sort looked at the black box under step and looked ok but wiggle wires and sometimes worked had a closer look and about 4 wires where all corroded just under the sheathing going back down the wires theory where all powdery chopped then off and re did all the dodgey looking ones sorted.

Iv run with a dead Altornator other year after welding and killing it everything worked fine apart from the Rev counter.
Fine washing them just don't blast under that step

We had the wire on 3095 coming from the alternator where it joins another brown wire about mid engine block on right hand side go all green cleaned it up and away it went
No alternator no charge, lift will go first when battery voltage drops below 12v

 

[Westside]

Thanks for the help. Still no luck with the tractor ... I've put a multimeter on the alternator and I've got a 14v output. Cleaned and remade a few connections and have rhe lift back. Now don't have diff lock, pto, hi/lo or splitter.
Is there any common feed for these?

 

[Cooper3075]

I could be the black box itself has issues I know my cousins 3125 had to have a reconditioned one twice due to being at fault I can't rember what stoped working though.

 

[Westside]

Thanks Cooper... I've spent a good few hours on it today. Just seems strange that this has all started from washing it! Do you know where these fuses are above the radiator?

 

[masseybreaker]

the fuses are above the battery if you follow the red and yellow wire from the battery + you will find them if not them follow the wiring harness from the solanoids back to the auto box and clean and dry the plug they are connected with one plug if that doesnt work report back there are a few other known problems

Is the Rev counter working??

 

[Westside]

Rev counter works. Been dung spreading all day so not had a chance to look at that tractor today but I tried cleaning the wiring harness before and all the connections to the solenoids.

Those are all Autotronic functions you have lost..
Is power going to the box as mentioned by @masseybreaker?
Check the wires going to and from the pressure switch, it's located on the same side as box under step, behind the wheel, if it doesn't read enough pressure it locks out P.T.O

 

[MF-ANDY]

if you have lost autotronic AND elc i would think think you have a broken wire from the battery to the two fuses near the air filter. you should have a red wire coming from the battery which splits into a red and yellow in the harness and then feeds the two fuses, red for elc and yellow for autotronic. check for 12v at these fuses with a heavy test bulb NOT a multimeter.

 

[Cooper3075]

Can I ask why not to test with a multimeter?

Multimeters don't draw enoght current and can give you a false reading, there's nothing better than a good test bulb for sorting electrical problems
These wires sound like the most likely cause of the problem if you have no luck I can probably find you a wiring diagram that shows you how to test the autotronic box
