Double check the battery to ground connection. Check ground to engine block and make sure you have good ground to starter which is normally grounded through the engine block to bellhousing.

I will check that out...thank you Kerry!

When you press the starter button, do you hear the click of the starter solenoid?

Good morning Jon! When I push the starter button there's nothing at all, much like a dead battery.

...then you needn't remove the starter, because the problem is upstream from the starter.  Possibly in the solenoid or wiring from the starter button, or in the starter button itself. 

1. When you push the button and the starter isn't energized, do you in fact have power/  Will the horn beep, and the headlights come on?  If not, then either the battery is dead, or you have a bad battery / ground cable connection.  (Sometimes when there is a bad battery connection, the headlights  will come on, but the starter requires so much amperage to run, that it won't run.)  Using a battery cleaning brush, remove and clean all the cable clamps, and make sure your ground strap is grounding.  To be sure, remove the ground strap and sand off all the paint and rust beneath it, on the body or engine, so it will ground correctly.

2. Start working back from the solenoid. If it doesn't click when you press the starter button, try running a wire from the hot battery terminal to the solenoid. (To whatever solenoid terminal connects with the starter button.)  Doesn't work?  Then see if there is continuity from your starter button to the solenoid.  If so, then check the button itself.  Is it getting power from the ignition switch?  If not, the problem lies either in the ignition switch or maybe the line from the switch to the voltage regulator.  Keep checking back, back, back, each step of the way to the battery.  (Of course you'll check the battery condition first!)

My guess is the problem lies somewhere between the starter switch and the solenoid.

Very common, and that's essentially what it usually is -- no amps getting out of the battery.  Not because it doesn't have any to give (dead), but because the pathway is compromised.  I would remove your battery terminals from the posts, clean both posts and terminal, then reinstall.  Also check to see if your wires going into your terminals are loose or corroded.  I experience this issue multiple times a year with my various old cars, and it's almost always a bad connection.  Won't necessarily show up on a multimeter, either -- you can have 6 volts at the solenoid or even at the terminal, but if the pathway from the post to the terminal is sufficiently restricted, you won't have enough amps to accomplish anything.

I carry a small standard wrench set in my cars to deal with this.  Pro-tip: do not store this in the glovebox, the weight is too much for the cardboard!!

Let me reiterate some of what others have said:  make sure the battery terminal connections are CLEAN and tight.  Make sure the connections to and from the solenoid (it’s really a high-current relay), and to the starter are CLEAN and tight. 6-volt systems require TWICE the amps as 12-volt systems, thus they are more sensitive to dirty, high-resistance connections. 

Next, check for correct voltage at the solenoid connections and at the starter when energized. I’ll bet that cleaning the connections will
solve the problem. If not, try jumping the car from another 6-volt battery.  If that doesn’t work, then the starter almost certainly is faulty.
