To send electrical voltage to the starter when engaged.
solenid switch engages and disengages the bendix on the starter
This switch is designed to be sure that the car won't be moved by the starter motor. It requires that the car be in neutral, park, or have the clutch depressed before the starter motor will engage.
My '77 F250 also has two solenoids for the starter, one on the fender and the other on the starter. The one on the starter is the one you'd expect and has a mechanical function, it moves the starter gear to mesh with the ring gear on the flywheel to turn the engine over. The solendoid on the fender has an electrical function as a relay. A relay is basically a switch operated by another switch. In this case, the controlling switch is the ignition switch and the switch it operates is the solenoid. The current needed to operate the starter is so great that it would wear out your ignition switch plus require huge wires running from the battery to the dash so instead of switching this huge current, the ignition switch switches only the smaller current needed to operate the solenoid and the solenoid switches the huge current. When you turn the ignition switch on, it energizes the solenoid which closes the circuit that supplies current to the starter.
You have a starter/ignition switch mounted in the steering column and you have a starter solenoid switch that is mounted to the starter.
Starter solenoid?
where is the starter relay switch on a 1996 Toyota corolla
It is a switch that temporarily connects the battery to the starter
The starter relay is built on the starter.
Usually when a starter solenoid/relay switch is bad, you will hear only a click and the starter will not spin (crank).
might be starter relay, or the crank circuitry from the switch or to the starter from the relay. I would trace back from the starter to the starter relay back through the neutral safety switch to the ignition switch.
Function Of Change Over Switch
The starter solenoid is part of the starter.
