I heard that sometimes if there is no charge the generator has to be polarized again by connecting it to a battery for a few seconds so the generator will work like an electric motor. It has to spin to the same direction as it will when used in charging. This has something to do with the remaining magnetism in the generator field coil. I think that the polarizing restores the small remaining magnetism in the field coil. When the anchor of the generator spins in a magnetic field it produces electricity. The amount of produced electricity depends on how strong the field is. The field coil is an electrical magnet that gets its power from the generator itself and there is no magnetism in the field at first when the generator starts to spin except the small remaining magnetism. This helps to produce a small current to the output which goes to the field coil and increases the field a little so the output current increases a little and so on. When the output voltage increases enough the regulator cut-off relay will let the output current go to the battery (some of this current still goes to the field). This all happens in a few seconds or less. This is how I have understood it. Maybe someone will explain this better and/or tell me that I'm wrong.

Tuning-Up Your Tractor: Secondary Ignition Wires and Distributor - by Curtis Von Fange. In our last episode we spent the entire day checking out the spark plugs. Is that efficency? Actually, it took more time to explain than it really did to do the inspection. At any rate we decided that a compression test was in order so we could verify the internal engine status. That way we wouldn't buy any tune up parts until we were sure that the engine was in reasonable mechanical condition. Our tests showed a fictional compression reading of 85, 80, 82 and 86 psi. That is well within a
