The H just quit

I was raking hay the other day for about an hour and my Farmall H just quit like someone turn off the key. It still has a 6V system with a Delco distributor. There is juice to the coil. Could it be a bad coil?

Yes,when the coil goes bad it usually will shutdown the tractor after it gets hot. Sometimes they just go bad and quit also.
 
I had this happen a couple times: once a loose wire to the coil. The next a bad coil.

Here's a mind-bending thing, though: I've been told that sometimes evenly newly bought coils are bad, but that you can't test a coil. Anyone have a comment on that?
 
Many thing can cause that to happen so you need to start by check if you have spark to the plugs and gas to the carb. etc. I have seen that happen on many engines and it could be a problem with the gas flow points, rotor, coil wiring etc etc etc
 
Take a test light and ground one end and put the other end on the distributor side of the coil. With the points open the light should light just like on the battery side of the coil.

If the light lights, we know that we have continuity through the coil. If the light doesn't light, we either have an open primary coil winding or a ground either in the wire leading to the distributor or a ground inside the distributor itself. The test to determine which, is to unhook the wire and if the light now lights the problem was not an open primary winding in the coil but a ground in the wire or distributor.

Now have someone crank the tractor and the light hooked as above to the distributor side of the coil should blink. If it does you most likely have a bad secondary winding in the coil and need a new coil. If it doesn't then the problem is points and/or condensor.
 
See if it will start after sitting awhile. Could be the coil. If it starts and runs for awhile and quits again check for fire to your plugs ASAP when it quits. If you have fire its probably a fuel problem & could be starving for gas. Hal
 
The tractor didn't sputter or anything when it quit. Got to be electrical. There is voltage coming to the coil but no spark to the plugs when I crank it over. Even bad points will make it miss a long time before quiting. What about the condenser?

I've had tractors just up and flat die, no sputtering at all, and it was because the gas tank just went empty. With a gravity flow fuel system, there is no recovery. When the tank is empty, it's empty, and the engine stops running.
 
Everytime I've run mine out of gas cause of the line plugged with rust, etc, it just died right off. Not like a car where the fuel pump keeps trying to feed a spurt here and there so it sputters around for a block before it quits driving.
 
the very same thing happened to me earlier this year with our H, and delco dist. Yes, first trouble shoot where you have power, work through the whole system. I had other parts to swap, in the end just bad points. Now runs great again
 
If you have another tractor, take the coil off that and try it. You have nothing to lose except time, and you're already wasting that wringing your hands and fretting over what's wrong.
