Bally Solenoid Driver Connector Map

This table maps all the Bally Solenoid Driver transistors to their corresponding connector pins, plus shows the corresponding decoder output pin, Pre-driver IC, and pre-driver pins (base, collector). These mappings are universal for all Bally AS-2518-16 and AS-2518-22 Solenoid Driver Modules and may help you to fix your solenoid problems.

Transistor Connector Decoder Pin Predriver Pins (B,E)
Q1 J1-2, J2-9 2 U1 (16,1)

Q2 J1-3, J2-4 1 U1 (3,2)

Q3 J2-5, J3-4 6 U1 (6,4)

Q4 J1-5 7 U1 (8,7)

Q5 J2-10 3 U1 (13,14)

Q6 J2-11 4 U1 (11,12)

Q7 J2-12 5 U1 (10,9)

Q8 J5-10 8 U3 (16,1)

Q9 J5-9 11 U3 (3,2)

Q10 J5-15 13 U3 (8,7)

Q11 J5-14 15 U3 (6,4)

Q12 J5-13 14 U3 (10,9)

Q13 J5-12 9 U3 (11,12)

Q14 J5-11 10 U3 (13,14)

Q15 Flipper Relay n/a U4 (3,2)

Q16 J2-6, J3-7, J5-8 16 U4 (8,7)

Q17 J5-7 n/a U4 (10,9)

Q18 J2-15, J3-9, J5-3 n/a U4 (11,12)

Q19 J2-8 n/a U4 (13,14)

n/a - These are for "continuous" solenoids and are controlled directly my the MPU without using
the decoder circuitry (e.g., coin lockout coil, flipper relay, etc.)
