Hello group!
It's been over 35 years since I did any solid state repair so I'm a little rusty.
I'm having an issue with a F-14 Tomcat that I could use some understanding of how the I/O functions.

Ok... Switches in the play field fire transistors on the motherboard. As a means of isolation (higher voltage controlling lower voltage)

The motherboard fires larger transistors in order to fire coils... (lower voltage controlling higher voltage devices.)

I have a slinger solenoid that fires and stays on from the moment you power the machine.
During the first switch (05) test, the motherboard does NOT see the slinger switch.
During the second switch test (06) the motherboard does NOT see the switch.

I can physically see the reed switch.. the contacts and clean and if I directly short out the switch still nothing.

So my question is... is it possible that my Q46 transistor has failed in the PASS state which is telling my slinger coil to energize?
Or is it possible my transistor TO the slinger coil has failed in the PASS condition?
I found the transistor for the input... but I'm not finding a transistor labeled for the Left Slinger coil.

Help me Obi Wan....

Thanks!
