I am having a problem with a project machine I picked up over xmas. Gottlieb Gaucho.
It arrived not working but with a bit of jiggery pokery I managed to get it up and running (mainly cleaning switches, score reel,etc.).
I noticed the left flipper was weak so changed both solenoids.
Powered up and this is what I get....
Sounds like it's doing a reset, if I manually shift the scores on the backglass then they allreset back to 0 and the reset bar "clunk" can be heard.
115v hold relay is active but the 30v hold relay is not. If I manually hold the 30v relay the playfield lights up but still no response.
That is it there. Player one doesn't light up (bulbs are good) , no response from flippers or and targets if I run the ball thru the drain, it wont even activate the solenoid to allow me to launch the ball.
One other thing.....
When I try to add second credit, it performs the same reset and player 2 lights and goes out again. Also replay button doesn't do anything.
I attached the schematics (poorish quality I'm afraid but I can get better ones if any needs specific bits.
Hopefully someone can point me in the right direction, thanks for your time.
