Ford 7740 dual power

[John 1594]

Got one of these due in next week....among its listed faults are the 4wd wont disengage, and the handbrake relay and light are constantly buzzing even with the handbrake off

You all know how much i love fixing electrical problems, so which wires do i need to grope at in order to find whats up with it? 4wd will be spring engaged, hyd solenoid disengage? New relay for handbrake or just pull it out completely? Not bothered if handbrake light works, just need to stop it buzzing all the time

any suggestions?

Crap little switch under the handbrake Is the usual on them

 

[Badshot]

4wd comes in with the handbrake being applied. Fix that, fix 4wd (with luck).

Switch seized usually.

Its on an equestrian unit, lets just say its not well loved

first job, before all the above, it to weld the exhaust back on to stop it blowing smoke up the cab window

Got a bomford cam lock loader on it too, rather oddly thats plumbed directlyinto the two rather stiff cable controlled spools as opposed to a joystick, also on wide low profile grass tyres

shes certainly a bit of an oddity bless her

 

[Kevtherev]

Yes I've seen a few plumbed into the spools.
Bit odd system[emoji50]

especially when you want to open and tip a hydraulic tailgated trailer

If it was me, and i had to be constrained to running it via the spools, id have a male hyd coupling into a T piece, then a tap on the T branch, with loader feed off it, and female coupling on the run of the T.. would mean turning taps off, but much easier than having to unplug 4 pipes every time you want the rear spools in use?

 

[Kevtherev]

Yes I've seen them teed in with taps.
Not ideal but does work.
Rather a proper joystick myself [emoji106]

This is true stock farmer spec....its got enough electric tape and red string in the cab to re-rig the cutty sark!

Just check brake lights work. That and 4wd share the same fuse.

Brakes on 4wd engages iyswim

In fact if it's doing mainly yard based loader work in 2wd it's often best to fit an override switch to stop 4wd engaging with braking. It saves the front axle no end of grief.

 

[John 1594]

It does some strange things....the handbrake relay/light is on when its idling, rev it to a certain point and it starts intermittently flashing on/off and clicking like the indicator relay does, but the 4wd seems to remain in gear all the time

 

[Flat 10]

Check alternator output

 

[Drillman]

Actually this is a bit of a cheek! The DB man who doesn't like Fords now needs our help

it just needs a new flux capacitor, us ford boys know where it's located but where not telling

Ah but with the ford you will only get paid if we tell you

A- where the flux capacitor is (and what it looks like)

and...........

B- how to replace it


Now obviously we can be bought for this info but I will have to consult with @Nearly @7610 super q And @cfr1964 amongst others about our fee!

Can't offer much help....40 series electrics are a mystery to me as well. Unfortunately the previous owner of mine was a bit of a pillock-bodger and has disconnected all the connections, presumably looking for problems, and taped them all up again....badly. Not had any problems so far......but I won't be pressure washing underneath in a hurry.
Mines 2wd as well, thus avoiding any front axle issues.

Edit- BFF has a good thread on 40 series probs....

flux capacitor is something to do with time travel,
john dont move it backwards or you will get a porous block
and if you move it forward you will have a big pile of sh1t

 

[bovrill]

Just check brake lights work. That and 4wd share the same fuse.

↑↑That↑↑
Before getting too excited with wiring, just check the fuses are OK!

And when i get the ford out of dry dock.....my next job has just been lugged down the driveway by a very out of breath courier driver!!!
