Let's just cover everything again to make sure nothing is getting missed.
The solenoid has four connections. Two studs, each with thick wires attached. One stud goes to the battery positive terminal and the other stud goes to the starter motor. Doesn't matter which goes to which.
The other two connections are small wires that are used to activate the solenoid. Depending on how your controls are set up, there will be one of two situations:
1.) One wire on the solenoid goes to power (black wire in the harness) and the other wire goes to the yellow/red wire that leads to the starter button.
2.) One wire on the solenoid gets grounded (green wire in the harness or bare metal on the frame) and the other wire goes to the yellow/red wire that leads to the starter button.
If the solenoid clicks when you press the starter button, you know you have it wired correctly.
If the starter is not working when the solenoid clicks, you have one of the following scenarios:
1.) Starter is non-functional (I believe we've ruled this out because you can use the starter to turn the engine over if you connect it directly to the battery, but it still might be worth bridging the solenoid studs with a wrench just so we can rule out bad cables, too).
2.) Solenoid is non-functional. Two bad solenoids is unlikely, but possible.
3.) Bad starter button. I had this problem on my CX500. The solenoid would click, but the starter button was on the way out, so I wasn't getting enough current to get a solid switchover from the solenoid. I'd get the click, but a poor connection. We've ruled this one out by jumping the thinner solenoid wires that I had mentioned a few posts ago.
4.) Bad battery. I think we ruled this one out already as well? Jumper cables from a car battery is the way to check this.
So assuming that we've checked everything in step number one, I can't think of anything else it might be besides a bad solenoid.
Are all my assumptions and statements correct so far?
