if you have a wire right from the battery to the blade terminal on the solenoid then there is no breaker to trip. You will have completely wired around that system. So if it still does not work then you either have a bum solenoid or starter

Good catch 98.
Or the wire between the relay and the solenoid is shorting to ground. Asked OP about this back in post 11.
OP, disconnect the green wire from the solenoid (move the wire as little as possible), press the start button, does the breaker trip?
If it still trips the breaker, I think we can we can eliminate the solenoid from the suspect list...

so it does not work, and the solenoid will work on a bench test. Its only shorting out when its grounded to the bike. Off the bike Ive run the whole push pull test and it was just fine, as well as tested the starter and it spins freely. Right now I have my jack shaft off so theres no load on the starter from spinning the clutch and countershaft.

The `90 FXR is not wired like the old Softails...
The old Softails got power for the relay from the main breaker.
The `90 FXR starter relay gets its power from the accessory breaker.
You are going to have to do some wire tracing now, to find out how this bikes starter circuit is laid out...
Find the starter relay, and trace the wire from terminal 30, tell us what it goes to...

Yes. With no other wires on the connector on the solenoid that pulls in the solenoid when you push the start button, then touching a wire between the battery positive and that connection on the solenoid can not possibly trip any breaker. Why do you say the breaker trips?

my bad its not tripping the breaker, but it is drawing enough power to shut off the headlight and give it the appearance of a breaker tripping, except with no reset time. I disconnect the wire and the headlight goes back on. To clarify though wire directly from positive to blade connector and the starter/solenoid do nothing

If you did what I said, the breaker would not trip because you bypassed the breaker. Worst case, the wire in your hand would get very hot, and you would hopefully remove it before it went too far. Best to use an ammeter on it, as I also said. So, what exactly did you do? Or better yet, do what I said and let's see if the wiring is bad or the solenoid. Also, remove the wires and measure the resistance of the solenoid pull in to ground with a quality DVM.

If you connected a jumper wire from the positive post of the battery and the small terminal on the solenoid (where the green wire goes) and the starter did not crank, the problem is the solenoid.
