I've been studying the circuit diagrams and operation of various electrical functions in the service manual for the Kioti DK 35 45 50 tractor.
I see a number of relays (not all, but some, including the start relay) that have a diode placed in a loop around/between the terminals for power and ground on the coil circuit. Having dealt with this style relay for years, I don't understand the need for a diode in this application. Maybe someone can give me a "nutshell" explanation for why that might be needed?
I'm not looking for long winded breakdown on the theory of diodes/rectifiers, atoms and molecules, protons and neutrons or any of that. I know what a diode does. I just don't see why there would be one here.
