Hi all

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.

OP
Quoted from brentg:
115v hold relay is active but the 30v hold relay is not.

Let's start with the 30v Hold relay then. I can barely make out your schematic, but the H relay looks like this one from Sweet Sioux:
Sweet Sioux H relay (resized).jpg
In this drawing the H/30v Hold relay fires when a switch on either the B relay or the SB relay closes. After that the H relay holds itself on through the H relay switch. None of this happens though if the T relay switch isn't closed (which it normally should be).

If your H relay doesn't fire at all, check that the T, B and SB switches are clean and working and that either the B or SB relay fires.
If your H relay fires but doesn't hold, check the H relay switch.

This is the H 30V Hold Relay on my diagram a bit clearer (looks similar enough to yours by way of relays).

I shall check on the T, B & SB relays.

Thanks Mark

I would look closely at the t (tilt) relay first. Make sure it operates by moving any tilt switch.Make sure the relay is actually making contact,ie...switch is making contact and clean.Coil on switch stack is actually good.Might us a meter just to make sure switch is closed.
Also make sure the closed slam switch is making contact
Dirt can be a real problem with any machine,especially one this old.
If all is Ok,then move to b/sb switches.
I'm guessing o manuel with machine so no start up sequence.
Let me know by PM if you need more help. I have a Gaucho.
