I read numerous people bypassing this relay and not replacing it because it notoriouslly goes bad,Then another person said the solenoid acts like a relay in a sense so with so many people bypassing and not replacing I'm not sure if I need it?For instance take headlights as example with headlights the switch sees constant voltage as long as the lights are on so a relay is needed or the switch will burn up but with the starter its just a few seconds of load and I think this is why they don't add a relay?
