mkirsch said: (quoted from post at 04:48:14 09/09/14) Yeah, 14.8 is about typical in a vehicle, so the alternator is working as it should.
If the ammeter drops back down close to 0 when the tractor is running, but no lights or anything else, it is working fine. When it stays at a high charge rate all the time, is when you start looking for problems.
The coil may or may not be too hot. I don't know what your idea of hot is.
One thing you need to be careful of is that there are *TWO* different types of "12V" coils. There is a "ballast resistor required" and a "no ballast resistor required." It is easy to imply the "no" if you're reading the package quickly and end up with what is really a 6V coil.
There was an 1C14 from Napa on it and I replaced it with the same. No difference in temperature.
It was used for 2 hours tending hay before I tested it and the battery was not hot and voltage stayed steady at 14.8 to 14.9
The coil is hot enough to want to let go of if you grab it, but not so hot that it burns you. (you could hang onto it with no ill effects).
EDIT
So with some research on regulators I confirmed what mkirsch said, that in fact most regulators have a 14.8 set point. When I get to it I may change it out for a lower voltage one to see if it helps with the heat a bit. I am going to take it that my volt readings are normal and the coil is hot, but not overheating.
Tractor is running and starting much better, but stalled out once after tedding coming to low idle when he was done. There was some condensation in the cap, I think from sitting for a month outside so I will chalk it up to that.
I think new cap and rotor, gas tank cleaning, and rewiring should be on the not so short list.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
