Have been working on a full rebuild of a Gottlieb World Fair from 1964 for about 8 weeks.

Now this game was an absolute mess, have never seen a game that needed more work to bring it back to life. She now has been fully rebuilt but there is one 'bug' that is just giving me the f**king shits so much I feel like setting it on fire 

The playfield lights have a short - do you think I can find it?

Have just blown the (lost count) 10 Amp fuse over the past few days...so have come into the house to vent my frustrations here....and I don't feel any better!

So an the title says, the hobby can be just the best, can give the best rush - just sometimes you want to pull your hair out 

LOL!!! Mate,

I KNOW where you are coming from on this..
Is it GI lamp or feature?

If GI, disconnect the whole PF from the back board etc, take out ALL Gi lamps and put your meter across a socket. Is your short still there? If so you have no choice but to find the very last lamp in the series, disconnect one side and test the socket, should be no short here ( unless you are lucky and this is the one!).Shorts should still be seen across next lamp though. Continue up the line till you find it - can resolder as you go.

Painful job, but its the only way to find the bugger.

If the short disappears when you disconnect the PF then its elsewhere - maybe through the GI relay contact - those little frayed wires cause havok and are hard to see, maybe also on the female side of a socket, tiny bits of wire or solder splashes seem to migrate to these sockets, unscrew them and clean em up.

Good luck mate - i hate this job...but you will laugh in triumph when you find it- you know that!
