The clicking sound is the plunger partially engaging. You have to remember that the plunger not only engages the contacts for the high side of the soliniod but it also has to enage the "throw out" gear that engages the starter motor to the engine.
If the plunger doesn't have enough force behind it when it initially engages the throw out gear makes initial contact with the engine and fails to engage fully, thus preventing the electrical contacts in the start solinoid from making cantact or they make partial contact which is insuficient to allow the starter motor to turn, hence the hum some times heard.
This is an electromechanical system and you have to look at how the two interact and are dependent on each other.

Not on our starters, the gear is engaged by the rotating of the starter motor. The only purpose for our solenoid is to make contact between the contacts and the plunger.
It is virtually the same as that spot light relay that is being proposed.
Yes, I meant a single click, and that was my experience with starter problem. I was picturing myself turning the ignition switch 3 times when I typed that
I've been pondering this all night and the only thing that I've come up with is that maybe the plunger is bouncing off the contacts enough to break contact and not have the motor spin up.
But that still doesn't make sense as the solenoid has it's greatest effect when the plunger is at it's deepest point within the solenoid. So if it starts to move it should have enough force to hold it.
It will be interesting to see what fixes it.

Replaced both the main starter cable to the battery and the ground cable this morning. Thus far today, no "no-starts". Both of the old cables looked fine. Replaced them anyhow. We'll see.

This is very interesting. This link details different reasons solenoids fail:

Ron, keep us posted. I'm awaiting plunger and contacts from Cdan. Should be here Monday and i'll post up if it fixes my issue.

Sure thing. Hope contacts and plunger is your fix.
My '93 1FZ starter used the solinoid to engage the throw out gear when I stripped it whilst tring to fix this exact problem. I assumed the ones you guy had would be the same. Sorry if my info is misleading. Seems there are some more basic differences between Oz and US 1FZ 80's.

That's a significant difference between US starters and Oz starters.

Bad Landcruiser! Bad boy!
First non-start happened this morning. First non-start since I replaced the cables yesterday morning. Bummer. This sucks.
The ignition switch comes in later next week.

My '93 US 1FZ starter operates the same way. The clutch pinion gear test outlined in the FSM, is done by applying 12V to the solenoid.
That's because you need to spin the motor to move the pinion out.
Next time you have a starter out, turn the pinion gear by hand. In one direction it will spin freely and the other direction it will move out toward the flex plate.

That would seem like the only thing left at this point. Unless that used starter had similar issues.
How much does that switch go for?

Lets hope its not the used starter.
The ig. switch goes for seventy-something. Don't remember exactly. Its a special order. Not coming from Dan's stock.
I'm pretty sure there is a relay between the starter and the key. It's a safety feature that won't let you crank the starter if the shift isn't in PARK or NEUTRAL, and in an old LC like mine, I sometimes have to move the shift lever a bit to make contact with that relay, wherever it is, and thereby engage the starter.
You could probably check if you have one by putting the LC in DRIVE or some other no-start gear and try the starter. You should hear a significant CLICK. If so, it's just a matter of moving the shift lever around a bit in NEUTRAL or PARK until you can start the LC. I have no idea of how to clean my contacts, wherever they are or which of the countless relays is the one for the safety shift thing. It's a simple check so try it.

This doesn't mean solenoid is not used to move the pinion gear. Otherwise, there will be no need for such test.
How are you going to spin the motor to move the pinion out?
I am aware of that.
now I'm going to have to pull my starter to see what's going on.
