Firstly I have to say thanks to Nino and everyone else who answers my questions.

I'll try cut down on questions in the future I don't like to 'use' people's knowledge, if you know what I mean. This site has been a huge help to me.

Both fuses still blow even trying one at a time, so, disabled the G.I, and now the attract/playfield lights are BRIGHT, clear, and fully working .
Run the test and everything except G.I. is working fine.

Now checking for a short in the G.I. chain. Hopefully I can avoid having to check boards in the backbox, see how we go.

Thanks again.
