Which is the ground terminal on a fuse box starter relay?
The “S” terminal (or 85 terminal in some relays) receives a 12-volt signal from the car’s battery. A small current, usually less than 10 amperes, passes down the terminal and through the coil windings and through to ground. In the fender-mounted relays, this is the “I” terminal. In fuse box starter relays, the ground is terminal 86.
