Will check

[infinite1977]

Connectors fine. Definitely transistor on cpu
 Ahh well

GI should work independent of CPU problems.

Are all Gi strings out?

[infinite1977]

No not all lower playfield

Transistor for lower PF G.I relay had locked on last time, energizing GI relay permanently when the machine was on and turning G.I off.
to prove this is the case with machine off unplug J12 on driver board, turn machine on, if G.I illuminates then the transistor on the cpu driver board has failed (Q9)

J12 on cpu board or interconnect board

[infinite1977]

Yep unplug J12 on ICB GI comes on

[Steevsee]

Beaky to the rescue!

[infinite1977]

Always. Damm you both for being so far lol

Is it the same amount of G.I out before you sent be the board or less?
If it's only 1 string out then it won't be the transistor for the G.I relay.
Try un pluging the connector I mentioned before

Same as before. As mentioned above. When I unplug J12 from ICB all lights come on

it was J12 on cpu / driver board but solenoid 10 (G.I. lower PF relay) goes through J12 on ICB so unfortunately you have blown the transistor

Ok thanks. You know the drill lol
