3. Driving a solenoid, in its simplest form, is a matter of switching the current on and off, usually done with a low-side MOSFET switch and current recirculation diode.

The ignition switch is typically inside the steering column, where it shares space with a lot of wires and the steering shaft itself. For theft protection, it’s designed to be hard to access.

The solenoid is essentially a high-current relay used to control the application of battery voltage to the starter motor. Like a relay, a low-current control signal is used to switch the high ...

Electroswitch control switch relays (CSR) combine the function of a control switch with a remote-controlled solenoid, allowing one device to do both the manual and supervisory control function in the ...

But if the solenoid is truly dead, there's no choice but to replace it with a new one. You might think you could simply jumpstart your car , but it's not so easy with a dead starter solenoid.

1. This switch-mode solenoid-drive circuit maximizes hold-mode power savings by using comparators to efficiently manage drive waveforms. The circuit presented here (Fig. 1) takes the same power ...

We don't want to switch 12v to the solenoid and the TCU terminal at the same time. The TCU is meant to put 12v OUT, not get 12V in! This could damage the unit.
