  Loss of Residual Magnetism (Most Common) Generators work by moving electrical conductors through a self-created magnetic field. However, generators do not contain any magnets. The magnetic field referred to is created by taking some of the generator output voltage, converting it to DC, and feeding it into a coil to make an electromagnet. Generators start up by using something called residual magnetism. This is a small amount of magnetism left over from the magnetic field that was created the last time the generator was running. This little bit of leftover magnetism is enough to produce a small amount of electricity. This small amount is used to create an electromagnet. As the engine begins to turn this electromagnet, moving its electric field, through the stator windings, your generator will produce more power. However, if residual magnetism is lost, your generator will produce no power at startup. Loss of residual magnetism may be caused by the generation being out of use for a whil

I don't think the IC should heat as the current is only 600 m
