CONNECTOR IDENTIFICATION
BALL Y
games use a special technique to identify connec-
tors. Each connector receives a prefix letter, followed by
"J" (for jack) and a number. Connector pins are expressed
by a suffix number .
• The prefix letter identifies the circuitboard where the
connector resides .
• J-designations refer to a connector .
• The number identifies which connector we're referring
to .
• The suffix number (-1, -15, etc.) refers to a pin number
on the connector.
For example, CJ1 designates connector 1 on the Control
Board. PJ6-1 designates the first pin of connector 6 on the
Power Supply Board. Prefix letters for your game are listed
below.

CB - Cabinet
PL - Playfield
