Ok, another update:

You guys are right, the voltage regulator was really easy to remove. But none of the part stores in the area had any in stock. So it's going to show up on Monday.

Also, where would one go to find the owner's manual and service manual for this car? Since I have neither, All I've been able to do is the stuff that is found on this website?

Also, looking at the back of the clock, I only see one connection. Where is the second?
