Tip's: if a mechanical circuit doesn't work
then the electrical circuit can't make it work either
so checking the coils move freely and springs, EOS switches and levers work
would be a good idea first..so lifting the playfeild and check
all the mechcanical parts first would save from burning up mosfet's,coils
blowing fuse's over and over and damaging trace's.
Mosfets Transistor on the I/o power board
don't usally go bad by themselfs, something cause's
them to fail from my experience.
Is tapping the tab of the mosfet transistor with
a jumper to ground hurt the mosfet or is it a good way
to check a analog circuit without involving the digital circuit?
Using a circuit breaker first, in place of a fuse would save
from wasteing fuse's and the money to replace them.
Using a incondesent bulb in place of a coil would
help in deciding if the mosfet is leaky or shorted or being turned on
by either the shorted ic on logic board or a stuck playfeild switch..
A barely lit bulb inplace of a coil means the coil is being energised
when it shouldn't be..
What to check?
Are {pinball machines} like CD players,8 track tapes etc, Obsolete NOW
in arcades?
Are pinball machines so easy to fix that we don't need a Sticky
with tips and tricks?
