Hi Jack
Rolf is right, continuity is a tough way to troubleshoot an EM.
The problem you are having is due to the transformer,"a long rolled up wire". coils, "same thing", and bulbs, "test the same both ways"
a better way, is to do "hot" testing.
The bulbs will most likely have a common "ground" if you will.
testing one bulb to a switch, will read through ALL the bulbs on that common line, and can give false reading.
especially if one shud be on at the time.
So... get you a 5-6 volt wall wart, and use it to supply power to a bulb, then use the other end to trace backwards to its switch.
This is a MUCH better way to test EM machines.
The same goes for a coil, use a 12-30 volt wall wart, "assuming of course, you cannot use the transformer" for power.
clip one end to the BLACK/common return of a coil, and use the other end to trace backwards through the switches.

Quoted from jrpinball:

Good answer jr!
wall wart is a small transformer with plug prongs on it.
like your cell phone charger.
the transformer steps down the voltage to some smaller amount.
they have 2 wires commin off them to the device.
you cut the small plug off, strip the wires back, and touch the wires to the bulb socket.
