Started doing this intermittantly, but now all the time. It refuses to crank by turning the key. I can turn it to the "start" position, and something clicks about once every second, but no cranking whatsoever. I can get it to start just fine by jumping a wire from the starter motor positive to the solenoid positive, but that's the only way it will start. If I wasn't selling the car, I would just put in a pushbutton switch directly providing current to the solenoid, but that's not really an option because it would decrease the value of the car.
What could be going on?

I have had three Roo's of this vintage do exactly what you say.
The ignition switch contacts get burned and do not pass enough current to totally close the starter solenoid.
All three have been fixed by adding a relay controled by the ignition switch starter contacts. The relay is wired in at the starter solenoid and is very hard to see.
Any 12v lighting relay can be used.
Here is a wiring diagram if you would like to give this a try

I think if I were to do this, and was going to be wireing anyway, I would also figure out a starter lockout circuit into the system to keep people (or myself!) from running the starter while the engine was running. Probably could hook it to the oil-pressure idiot light if so equipped....

I tested the power to the solenoid and was getting about .25 volts. Definitely not enough to activate the starter.
Right now I just spliced a new wire going to the solenoid straight from the hot wire coming from the ignition "start" position. No relay or anything. Is this going to be bad? It starts just fine, but could it cause problems down the road by either frying something or sucking so much power so that other things don't get enough juice?
I don't think the solenoid uses that much power, but maybe I'm wrong, and the wire I tapped into was quite beefy (probably 10 gauge). It also would appear that it was originally set up without a relay. I may be selling the car tomorrow, so I need to get this worked out pretty quickly. So, do I need a relay, or is it okay like this?

Sure sounds like a "new fix" to me.
All mine have been working fine (for over a year in two cases)
But I am always up for new fixes.
Sorry I can not be of more help
