Ah, you are correct, after re-reading I see what you are saying.. I stand corrected on questioning your post. Just so you know solenoid isn't spelled solinoid.  Hope I got that right.. grin.

The test point takes any component out of the fault equation DOWNSTREAM from the X27 test point..so, if the starter cranks when we jump 12 v power to the x27 test point, we then know all is well from that point On..that includes starter, solinoid , cables ,starter ground, etc...and we now know the problem is UPSTREAM from the test point...just like I said ..K38 relay, ign sw. and NSS switch are then suspect, as that is the series circuit feed chain for starter soinoid circuit on that chassis.
The resaon we use that x27 connector is b/c it is the midpoint between the cabin feed [ ign sw/nss/and starter lock-out relay,K38] and the actual starter/soinoid circuit.
The point being, we are not concerned with a high amp jumpering when we jumper 12v to this test connection...it is simply a jumper of the cabin ignition sw and NSS/K38 lockout...very effectve and convienient test for a diyer , without being told to watch out for the high amp arching that a jumper to a starter would entail.
Ask around here how many have used the x27 connector test I post in order to remedy their No crank condition....... it is the first test one does for this condition and it is not a Dangerous Test..that is where I disagreed with the posters Warnings.
