REMEDIES FOR "TOUGH DOG" FLIPPER
PROBLEMS
SYMPTOM: FLIPPER DOESN'T WORK
If its End-of-Stroke switch is dirty or open, your flipper won't
function. Raise the flipper bat by hand, and push the flipper
button on the cabinet. If the flipper holds, the EOS is dirty.
But the rest of the circuit is good.
Clean and adjust the EOS so it's normally closed and
relaxed. At full stroke, the End of Stroke switch should
open.
If the flipper won't hold, go to the end
(co/d)
lug and ground
the flipper: You can do this easily from Control Board con-
nector CJ6. Identify the CJ6 pin that's wired to the flipper.
Connect one end of a jumper to this pin. Momentarily touch
the other end of the jumper to ground. If the flipper ener-
gizes, you have an open line between the flipper and
ground.
.-
LOCATING AN OPEN IN THE GROUND LINE. Keep the
CJ6 end of the jumper connected. Now walk the other end
of the jumper back from ground toward CJ6. Tap the free
end of the jumper at each connector along the way. The
next time the flipper energizes, you've located the open line.
It's in the length of wire you're jumping over.
FLIPPER STILL DOESN'T PULL IN. If the flipper still
doesn't pull in, your flipper solenoid may be faulty. The low-
resistance coil probably has an open winding.
SYMPTOM: TOP OR BOTTOM FLIPPER DOESN'T
WORK
The bottom flipper may rise, but the top one might not.
this is your game's symptom, the bottom cabinet switch is
bad, dlrty or misadjusted. Cabinet switches are normally
open.
