??? Which car are you referring to? The main cable goes directly to the starter from the positive battery post. Bosche relay mod aside, from the very fact that the starter clicks when the key is turned means its getting the proper 12V signal to the solenoid.

Two main things remain when you have a starter click but not turn the engine: Dirty contacts not allowing enough amperage to turn the flywheel, or a bad starter. I have seen both many times, thats why the next logical step is to clean contacts, then bench test the starter.

Ahhhhthankyou!
