5. Ckout:
Outhole,
Trough,
and Shooter Lane
This test begins with all the balls in the trough. It starts by "machine gunning" the outhole solenoid
to see if the outhole switch is wrongly activated. Two balls are served into the shooter lane, if a ball
is mis-served or if any trough switches do not open or close in time, they are reported in the display.
The test is normally stopped, and the operator can continue the test by pressing the enter button.
After the last ball is served, the trough solenoid is "machine gunned" and should not activate any of
the trough switches. When this succeeds, the shooter clears the last ball and "machine guns" also.
Then, the outhole is activated to feed the trough until all 3 balls are back.
Note, when an error occurs, press the enter button to continue the test.
Note, some amount of mis-served balls is acceptable.

Coin Slots
This test is for coin doors that are switch activated and is performed manually by the operator. No
audits or game credits are effected by this test. First, close the coin door so that the coin balancers
are aligned with the incline of the playfield.
The test will NOT start until the coin door is closed.
At
this point the coin door may be opened, but this test works best when coins are inserted with the
coin door closed. Next, identify which coin slots are being used by putting 1 coin in each slot to be
tested (the coin should activate the coin chute switch). Then, insert coins until the chute is marked
"OK". If the chute is marked "NG" (no good), look at the measurements of "ON" time. If it is more
that 500ms, the switch is considered stuck on. Typically, a quarter ranges from 40ms to 300 ms,
any reading above this can indicate that the switch actuator needs adjustment (the actuator should
be able to move all the way down and touch the bottom stop position). The full operating range is a
mimimum of 20ms (A.3 23) on to start, to a maximum of 500ms on, then an off time of at least
150ms.
Display Explanation:
The first number after the name of the coin chute is the debounced
millisecond "ON" time.
Note, the bottom two lines are a timing line of the coin switch.
Each dot represents 2ms
(milliseconds) of time (0.002 seconds). The left side of the screen represents the past 128*2ms or
256ms. The right 'side of the screen represents the current time. The second from the bottom line
of dots indicate a closed coin switch. The bottom line of dots indicate an open coin switch.
The slam switch (designed to ignore coins when the game is being abused) will make its "SLAM"
sound when activated (for adjustment purposes).

Switch Edges
This test is performed by manually operating all switches with a ball (never use fingers) at least twice.
It is recommended that each switch be activated 3 times. This will catch most sticky switches.
The controlled lamps are cycled in a pattern to reveal lamps that have a shorted diode. If a lamp
does not turn off completely, it usually has a shorted diode. However, more than 1 shorted diode
can falsely make others look bad.
All flashers are flashed for about 30 seconds. For Doctor Who there are 12 bulbs on the playfield,
10 bulbs in the insert, and 1 bulb in the Dalek (if used) on the top of the backbox.
