2. Managed to wriggle a screwdriver up to the solenoid and shorted across the two big nuts while a willing helper turned the key - there was nothing from the solenoid. No 'big wack", not even a click.
Shorting across the two large nuts - is what the solenoid does when it is operated when the key is turned to start the engine - the solenoid is an electricaly operated switch. The starter key does not need to be turned to the start position.
Shorting across the two bigh nuts - checks that there is power and that the starter does turn.

If the solenoid is good the starter motor could turn and rotate the engine.
