In order to make coils, bunches of tooth covered wires, typically called magnet wires are positioned together and found in the armature. The tooth serves as an insulator, which will help in avoiding heat between the cables in each coil. These cables are generally composed of copper, which may have problems with overheating or electric shorts. In order to avoid damage to the generator set, it's necessary to perform insulation testing, and plot the decay of the insulation over the alternator to understand the durability of the alternator. This sort of testing is completed with a device called a Megohmeter. Be sure to consult the manufacturer's hints for insulating material testing, even as each manufacturer will provide certain directions on how to examine the windings without damaging the alternator.
