That's very true (in most cases) IF there is a "CLICK" sound from the starter when the key is turned. (Mine needed an R&R'ing at ~ 42k miles.)

However, Vette 73, for clarification when 12volts is applied (one way or another) to the purple (solenoid) wire and there is NO CLICK, then the solenoid armature is either stuck (not likely - but not impossible), OR there is an electrical fault associated with the internal solenoid circuit.

Again, all this is spelled out in Marc's paper on "Diagnosing Starter Problems". But, just for clarification, that auxiliary relay that is often mentioned is a mod that applies specifically to the 90-92 cars. After '92 the start circuit was changed to accomplish the same thing, namely remove the clutch switch from the relatively high current (solenoid) duties with the help of a relay (which was incorporated in the 93-95 car's starter circuit).
