Starter solenoid

FED is correct given a few amps either way. It acts like a relay but it is not.

To be more specific, a Ford starter solenoid and a GM solenoid or a typical aftermarket mini starter solenoid are all different in design and different in amp draw.

*The Ford solenoid/relay is, as stated above, only "making" a set of high amp carrying contacts. With this design, the amperage load is small, only a few amps.

*The GM factory style solenoid serves two purposes. First, it engages the starter drive mechanically through a lever link that is moved to engage by magnet action from the solenoid. Second, it "makes" the contacts that power the starter motor. As stated above, this design draws much more.

*The popular mini-starter design is like the GM dual function but does draw somewhat less load because of design differences.

*Just for info, another solenoid design it the 100% duty cycle style. This is what we use when installing the solenoid activated master switch.
