Ford generator

Metaldetecting · May 18, 2019

I need help please. My dad has a ford 2000 series tractor we?ve replaced generator and voltage regulator started up fine left it in yard it caught on fire.
We?ve replaced it again and a wire harness smoke comes out of generator again. Can someone tell me what I?m doing wrong?

Welcome! Sorry for your trouble. But which 2000? There were 2 different models of it. 62-64 4 cylinder and 65 - 74 3 cylinder.

At any rate, you must have some wires crossed or shorted between the voltage regulator and generator.

Smoke coming out of a generator usually means that the generator itself is making power but that it has nowhere to go. If the regulator is malfunctioning, and the cutout relay is not opening, then this will happen.

This can also happen when the generator runs with no wires attached to it. The residual magnetism in the field coils is enough for it to put out a limited amount of power. With no place to go, that power turns into smoke.

esides year, was it running or stalled when it smoked?

very common when a wire shorts to ground... gets rubbed by something metal... or burn on the exhaust, or rubbed through with the hood edge or other sharp. also when vr sticks and goes full field...

Poor quality regulator and the cut-in relay is sticking together? I have it happen many times with aftermarket regulators with soft points. Cannot say I got a fire over it though. Just some melted wires. If the cut-in sticks together - all is fine until you shut the tractor off. Then it starts to overheat and melt wires.

By the way, I am not if there is anything else anymore except "aftermarket" when it comes to mechanical regulators. That is why I switch all my stuff over to alternators and electronic regulators. No current carried in the regulator and no points either.

Echlin (sp?) from NAPA still makes a good voltage regulator.

Started it up for maybe 5 seconds and generator started smoking then I pulled the battery cables off.

seconds is terribly short time for anything to get hot enough to smoke. But, I would verify all wires are properly connected at VR and at gen and polarize gen. before starting. Short duration re connect before starting as well.

You still haven't said which 2000 it is. Is it a 3 cylinder or 4 cylinder engine? The wiring for the generators and voltage regulators is different between the two.

Also, what was the original problem that made you think that you needed to replace the generator and VR?

It is a 4 cylinder the generator smokes after I shut the motor off.
