Ford 4000 electrical

Easterg11 · Aug 3, 2019

I have a Ford 4000 that I recently replaced the clutch and after reassembly the starter will not engage and the lights will not turn on when the switch is pulled out, when I turn the key on the fuel gage does come on, I tried to jump the solenoid with a screwdriver and nothing any help would be appreciated

Easterg11,
Welcome to the Ford Board.
Always mention whether you have a 1962-
64 Four cylinder model or a 1965-75
Three cylinder one.
Also tell us if you have a gas or
diesel.

When you replaced the clutch you split the tractor between the engine and transmission. The steering gear is mounted on top of the transmission, and the instrument cluster moves with the steering column when you split the tractor, so you likely pulled apart some electrical connections when you split it.

As Ultradog says, please mention if it is a 3cylinder or 4 cylinder 4000 as well as whether it is gas or diesel. Transmission type could be helpful in your situation as well as the S-O-S on the 4 cylinder 4000 has a different setup for the starter safety switch and starter button than the manual transmission 4 cylinder 4000 models.

This is something I have been looking for as im pretty sure the ignition switch does not have to bo for the lights to turn on

You have a bad connection somewhere, either at the battery or else the starter motor itself. Assuming that
electrical troubleshooting is not something you're comfortable with, I'd start by removing both battery
cables and cleaning all of the connections. Also, check to be sure that both "B" terminals at the regulator
are clean and tight as well.

Finally, I'm assuming that you checked the battery voltage, and it's at least 12.6 volts, correct?

Yes all connections are good and after further troubleshooting I found that a wire from the light switch had been pulled off probably from the fuel shut off cable removal and install, I did jump the starter from an auxiliary always hot wire and it did engage the starter so I m assuming a bad ignition switch

Found it I had unplugged the sensor on top of the shift cover
and knew this but until I traced it down I didn?t feel this had
anything to do with the starter but that wire from the starter
solenoid goes to that sensor whatever it?s for

It's not a sensor. It is the starter safety switch. It is in series between the "Start" position on the key switch and the primary of the solenoid. The switch only closes to complete the circuit when the transmission is in neutral (or Park if it is a S-O-S). It is to prevent you from starting it in gear and having the tractor lurch forward or rearward unexpectedly and possibly run into something or over someone.
