The relay is powered up and activated thanks to a small electrical current. When it is activated, it lets a current that is much bigger than the original one flow through other two outlets. It is used to control the headlights, the rear fog light, the electric fan, etc.
Turn key on, dash lights up, starter does not engage, turn key off, key stuck in ignition, short out starter relay starter works, when i try to start car dash lights up but starter does not engage??
