I had a coil where the vire was broken on the coil its self. I believe
Marvins guide says for 90's era games you can tell if it is broken by
checking for voltage on BOTH coil lugs when the game is on. If the
voltage is only on one lug, then the coil is broken somwhere. (make
sure door interlock switch is closed)
Please correct me if I am wrong.

I recently had a diverter coil that was blowing fuses upon activation
(FL11753) 3 lugs 2 diodes, I just swapped it out and the new one is
working fine.
Looking at the old coil, there is nothing binding in the sleeve. Would
this coil be salvageable? Could it have been bad diodes or is the coil
internally shorted and shot?
Thanks for your input,
V.

It hangs around on street corners smoking.
Usually they don't go bad. Other parts wear like plungers, coil stops, and
coil sleeves. Or poor solder joints, at the coil or another spot.
If you can't push the coil sleeve out, it's been too hot or worse. If it has
a dead short, it's shorted and bad. LTG

Coils do not "wear out". They can be physically damaged (errant screwdriver
pokes), they can overheat if they are energized longer than their duty cycle,
the insulation on the magnet wire can break down due to overheating, or the
magnet wire can break either at the terminal lugs or somewhere inside the
winding.
You can usually detect an overheated coil by discoloration on the coil
wrapper, or by visible signs of melting of the coil bobbin. Melting can cause
the bobbin to deform and interfere with free movement of the coil plunger.
As far as a coil "going bad" there's not a lot to check. Comparing the
resistance of the coil against another of the same type can sometimes indicate
if you've had insulation breakdown; a catastrophic failure often shows up as a
dead short or an open. Visible signs of overheating (discoloration, etc.) may
indicate a coil "going bad" due to insulation breakdown, but more likely would
indicate the coil is being driven beyond its duty cycle.

Check a coil to see what the resistance is
with an ohmmeter. If the value isn't known,
you can check it against another coil with
the same part number. In any case, you should
NOT read zero ohms. That will be no good
for sure.
Other than physical, visual damage, this is
the only way. They do not 'wear out'.

I'm suprised to see so many people say this. They do "wear out," in
that you can have a wire burn through or something, even if it's not
visual.
If you can't get the coil sleeve out, probably time to replace. One
thing I have done on a few bad coils is a continuity test on the DMM
from one lug to the other- if it's open, you have a bad coil.

Also, if it's less than 2 ohms and is not a flipper coil hi power side,
it may be shorted internally.
There used to be a site that had the coils with their resistence ranges
posted so that you could cross reference coils.... anyone know where
that is?

Well, that isn't "worn". It's "broken".
Open or shorted versus correct resistance reading.
It's yes or no, not "maybe".

Take the diodes off with a soldering iron then check the coil on a
multi meter. You may find out that the diodes have gone and not the
coil. (less than 10cents fix).
