Default Starting problems: testing voltage regulator

Ok so my dad and I are working on getting my car started. We finally get to the point to crank the engine to get some pressures built up (cranking it by disconnecting the coil that is...). When I turn the key, it doesn't turn over . The only thing we notice was a clicking noise comming from the voltage regulator. Does this mean that it is bad? Is there a way to test it to make sure that it isn't my starter that is bad?

Another question I wanted to ask was is there a way to "hotwire" the car, in a sense, so I can bypass the voltage regulator, or at least start the car from the engine bay?

The voltage regulator and starter relay are the only things on the car that were not rebuilt/replaced so thats the main reason why it could be one of those two. I doubt its the actual starter because it is a new/rebuilt starter.

If the battery is good the voltage regulator will not prevent cranking. Take a screw driver and bridge between the battery terminal ane the closest primary wire post. The starter should spin. If it does something isn't wired right in the starting circuit or if you have an automatic maybe the neutral safety switch is out of adjustment or disconnected.

What you hear clicking is your solenoid. It is clicking because the battery is too low to turn over the starter. Voltage regulators don't click.

+1 on the solenoid being the noise and as soaring says your battery could be low.

Thanks guys for the responces! I guess i'll recharge my battery (did it once, but that was awhile ago). If it does not work then, does this mean time for a new starter relay/solenoid?

why not jump start it if the battery is dead?

Well we kinda did, there is a mode on our charger that shoots 100 amps through to start the car. It still didn't turn over with that, so it must be the solenoid. We got a new one and I just hooked it up so I'll try it out soon.

and BTW turns out my battery was fully charged
