Quoted from northvibe:

You can use the manual to see which transistor drives the left flippers and if there is one or two for them.

It's not transistor driven, it's directly through the high voltage cab switch and the Q relay

It's probably not a fuse since all four flippers have their own fuses.

On the cabinet wiring you can see the left flippers have nothing in common until here, where they join to go to ground at A18J3. I'd start by finding this connector (probably down in the power supply somewhere) and reseating it. Check continuity from that white (9) wire on the the left flipper switches to ground and compare with the right switches

Quoted from Quadrider:

Do I do the same for the coils, referencing back to the manual on what the correct ohms should bring?

Yes

Quoted from Quadrider:

How do I test the transistor?

There is none
