Re: Crossfire cut out - engine won't start! Help please!
On most starters the solenoid is mounted on the starter and you apply power to the "S" terminal. This energizes a coil which physically moves a link that extends the Bendix into contact with the ring gear (flywheel) teeth. When it reaches the end of its travel a large disk makes contact with a terminal in the cap that provides power to the starter motor.
A few (Ford) use a separate solenoid mounted on the fenderwell however the text on page 8F-44 sounds like it is the first type.
"This electromechanical switch connects and disconnects the feed of battery voltage to the starter motor and actuates a shift fork that engages and disengages the starter pinion gear with the starter ring gear."
Further this sounds like you apply 12v to the solenoid and not ground:
"3. Connect a suitable volt-ampere tester and a 12-volt battery to the starter motor in series, and set the ammeter
to the 100 ampere scale. See the instructions provided by the manufacturer of the volt-ampere tester being used.
4. Install a jumper wire from the solenoid terminal to the solenoid battery terminal. The starter motor should operate.
If the starter motor fails to operate, replace the faulty starter motor assembly."
Now if this is not how it works, I will defer to someone who has practical experience. I have a lot of experience with starters (spent five years with Delco Remy) but not with Crossfires specifically and can always learn.
On some cars I could just bridge the big power and the "S" contact with a key and spin the starter.
