SOLUTION
Multiple balls in the shooter lane.
All 50 volt coils are inoperative
including the flippers. Auto
Launch Coil, Coil Sleeve and
Plunger Assembly may be dam-
aged due to overheating.
A modification to the Shooter
Lane Ramp should be made.
Lower the rear of the Shooter
Lane Ramp at the back panel and
move the front of the Shooter
Lane Ramp entrance as far for-
ward in the Shooter Lane Routed
Slots as possible. See Fig 1 and
Fig 2 pictorial layout of the modi-
fication.
The pitch of ramp is too great. In
most cases, as a ball is served into
the shooter lane, the Auto
Launch fails to shoot the ball up
the ramp. The ball returns, and
the Auto Launch attempts to re-
shoot the ball.

STEP
1
Remove all fastening hardware
from the Shooter Lane Ramp.
Remove ramp. Set aside.
If in Multi-Ball mode, balls are
STEP
served one after the other, ex-
pecting the shooter lane to be
free of the previous ball. The
Auto Launch cannot shoot eas-
ily 2 or more balls up this steep
ramp. This causes the Auto
Launch Coil to repeatedly fire, as
the balls roll back onto the
shooter lane switch which virtu-
ally causes the coil to burnout.
Drill new hole. (Fig. 1 ).
Another contributing factor will
be the pitch of the game -if leg
levelers are screwed out, the pitch
to the playfield ( and the ramp) is
increased.
STEP
2
3
Remount the ramp at the new
hole in the backpanel and refas-
ten ramp at the remaining 3 origi-
nal connections. It should now be
approx. 1/2 inch lower. (Ramp
should rest on the Mini-Mars lens
also attached to the back panel).
Ref. Fig. 1.
STEP
4
Position the front of Shooter
Lane Ramp as far forward in the
Shooter Lane Routed Slots a~
possible. Secure nuts. Ref. Fig. 2.
