I left my ignition switch on by mistake. Battery was dead when I discovered my error. What has been damaged ?

More tan likely the points. Maybe the coil too.

If your tractor still has the cut out relay, take out the points unit and replace it with a diode ( bridge rectifier ). I did that to mine about five years ago and even after leaving the key on a number of times when tinkering with it, I have never had a dead battery. The diode only allows current in one direction. I will post a picture tomorrow of a spare I set up and have not had to use.

The "cutout" in the charging system has NOTHING to do with draining the battery on an otherwise properly functioning tractor that has suffered the misfortune of it's operator being careless/forgetful and leaving the switch on.

At that point (engine stopped) it should have already disconnected the generator from the battery.

I agree with Bob, nothing to do with the regulator if it is operating properly.
I?m talking about the ignition points in the distributor not relay contacts in the regulator.

Points are probably burned up -pull distributor and rebuild, do not need any fancy components, OEM stock is just fine. While at it get battery tested, replaced if necessary, and fully charged if still good.

Why don't you just charge the battery and try and start it before you start throwing parts at it.

As cowdog said, charge the battery (see tip # 60) & try to start it. If it doesn't start see, tip # 38.

same here, altho in my case, it required swapping out the battery. it was marginal to begin with, and that little oversight killed it.

that was in my WD, which has a toggle switch for the ignition. that's on my list of things to replace this winter. i figure i'm less likely to leave a key in the ignition than to fail to notice the position of a toggle.

Leaving the key on will sometimes ruin the points. If it has been converted to 12 volt. It can burn out the diode in the Delco alternators.

I would just charge the battery, try to start it and see what works/ doesn't work.

I lucked out. Charged dead battery all day. Tractor instantly fired up like nothing had ever happened. I guess I have used up all my luck for 2018 !
Thanks for everybody's input.

Yep, you're a lucky man. If your tractor is 12v, you are a very, very lucky man. Go buy a lottery ticket!
