Ford 4000 3cyl. Do the have oil pressure amp gauge

jmducks1 · May 8, 2017

My ford 4000 3 cyl. Has oil pressure and amp gauge under steering wheel. Also has the gauge cluster. How do I wire in the amp gauge with the generator?

That tractor only had the rectangular instrument cluster when it left the factory. The original cluster only had gauges for temperature and fuel level, plus there were warning lamps for oil pressure and the charging circuit.

A previous owner must have added the other gauges. If they weren't wired up when you got the tractor chances are that whoever added them did so before they tried to wire them and never actually got around to doing it.

If the oil pressure warning light in the original instrument cluster still works then the original oil pressure sender is still in place and you would have to find a sender that matches the gauge that you have and replace the original sender with that.

An amp gauge works by being in line with the circuit that it is indicating the amps for, so it should be wired in line with the wire that goes from the voltage regulator to the positive terminal on the battery.

Best thing to do is replace the amp gauge with a volt meter.
To get the amp gauge working properly you have to cut the battery wire that goes for the regulator to the starter and extend both ends to the amp gauge.

You will find a brown wire connected to the start solenoid, on same terminal as battery cable. The other end of that brown wire connects to the voltage regulator "B" terminal. You cut this wire & insert the ammeter between the two cut ends.
If lights on shows discharge you did it correctly. If lights on shows charging, then reverse the wires on the two ammeter terminals. Simple as that.
