backglass lights

[pastiche]

The lower set of backglass lights have all gone out on my Data East Batman. It is the general lighting, not the flashers etc. Can someone tell me which connector I should be checking on the circuit board?
Thanks

J5 ppb board (top left) if it's not burnt out (usual) then it's dry solder joints.....that's the first stop...next stop power supply.....

For backbox lamps also consider the "z" connector, which is a white plastic connector block in the loom from the back box lamps to the boards. Should be situated in the hinge area of the lamp board and to the left of the pcb's.

^^^^^ All good advice above, the GI strings split out on the power board CN8, then in/out PPB J5 just to access the fuses, then through the Z connector to the back panel. With the high current drawn by the GI any/all of these could be burnt, crusty or dry.
