My Gottlieb Universe just developed a problem.
None of the playfield lights are working although all of the features on the playfield ARE working (i.e. flippers, bumpers, targets etc).

I checked fuses and all 3 seem to be ok.
I have recently ordered the schematic but I don't have this in hand at the moment.

For the last few days the lights would go out when I nudged too hard , but they would always come right back on.
Now they are off all of the time.

Give me some ideas of what I should look for.

thanks.

Check the 6 volt lead at the transformer, check the connection at the play field light fuse. Are the contacts at the fuse block clean and bright?

Some kind of fault in the ground line or GI line, loose connection somewhere especially since you said when you nudged.

If you use an alligator clip jumper from the playfield fuse block one of the GI bulbs do they all come back on? (NOT unit-controller bulbs as this would not work properly if the unit isn't on that bulb) Make sure you put it on the correct lead as to not cause a direct short. Also remember to use the fused side of the fuse block.

playdium Not sure which is the 6 volt lead but all connections at the transformer and playfield light fuse look good and clean.

otaku Is there a way to tell which is the fused side of the fuse block? How do I determine which lead is the correct one?
BTW, the lights are back working again... Various things seem to make them go off / on. So it must be something loose or a short...

One side should match the color of the 6V playfield wiring going to the transformer, that is the unfused side of course. Your mileage may vary but it should match, but I have seen it not match as well. Easiest well to tell it to remove the fuse and measure voltage on each side of the fuse block using ground on the transformer.
