4630 Stops Running

FNH4630

New member
I have a mid 90's model Ford New Holland 4630 that stops running at intermittent times.

I know what is happening but do not know the cause.

The power gets shut off from the fuel solenoid located at the bottom of the engine on the right side.

I can "jump" a wire directly from the battery to the fuel solenoid connector and the tractor will start up and run perfectly forever.

I don't know if it is a bad switch, a break in the wire going to the solenoid, or what?

Are there any known issues with this model and/ or what are some suggestions?

Many thanks

First of all, Welcome to NTT. Glad you joined up and hope you enjoy our place here.

Secondly, I have not looked at wiring diagram of the 4630, so I have no idea what may be involved such as relays. The switch would be the first place I would start. When it dies, check the switch with a meter to see if it has power going out to the solenoid.

Howierd, I am not sure what you mean by "the String".

Can you explain or do you have a photo?

I will probably replace the switch but it looks like it will be a bear to R & R.

Many thanks to everyone for the suggestions.
