With the key in the start position, if the relay in the solenoid circuit works, the thing to do is measure the voltage drop across the relay and also the voltage drop in the circuit to the starter motor. If...

I suspect you have a dead (or very low) battery, a failed alternator, and an electrical circuitry problem as well. It may be hard to tell which came first if there is wiring damage already. The clicking you hear is...
