Congrats! Big Guns is a fun game! I remember that you would get one shot mini playfield at the end of the game, and if the ball went into the lit hole you would get a extra ball! Very cool game...the cannons kick ass!

No, it's not. This is a *really* common problem with Big Guns though. One of my friends has one with this exact issue. I had it working for a while, but it's acting up again... From what I understand, the vibration of the cannons damages the diodes on the cannon trough switches. On his game, one was even cracked. I replaced them all, and had it working for a bit, then it started doing it again after a few games. So, I'm not so sure that was a fix. I also replaced the 555 timer on the board that controls the guns... no change.
I just didn't have the time to figure it out, and his game is in a location that's not too conducive to working on it, so I haven't slogged through to figure out what's going on.

I just checked it out. The switch is missing the metal arm. THere is no arm for the ball to hit. So, hopefully I can order one at Marco or elsewhere.
Going through the game this morning. This thing needs love!

If you can't find one and need a picture of what one looks like, I can help you out. It's like a long P strip of metal where the rounded part of the P makes contact with the ball. Doesn't seem like it'd be to hard to reproduce.

Thanks, bro! I have the metal arm on the right switch, so I can see what it looks like. Thanks!

Did manage to find one off the product number here: http://www.actionpinball.com/elect.htm
It's part #17-1067 on the page.

Replaced the switch and everything is working great. I found the part on pinballlife.com.
One little mystery...
On the right outside lane there is a gate. When the gate is open it closes the drain lane and sends the ball to the flipper. It's my understanding that this gate opens during "invincible" mode. However, on my game it never opens during game play. It doesn't open during "invincible" mode. However, during attract, the gate is open. So, the gate is working. The magnetic coil is working. It's getting power. The gate is open (relaxed) during attract. When you start a game, the coil energizes and the gate closes and never opens again.
So, this is confusing me! When I put it in test, the minute I got into the test menu, the gate closes. If I go to the gate coil test, the gate just sits there energized and closed. It doesn't open and close. It just stays closed.
Is this a transistor issue? On the driver board?

Wow, that is strange. That's a bad problem to have to because that outlane is a constant drain for me when the gate is shut.
The gate should be open at the start of every ball and during invincible. I had a similar problem with the drain-stop post. It would come up or go down at opposite intervals. The problem was that the diode had come off one connection. Once I set it right it worked.
Best guess would be to check the diode connections on the coil and make sure it's making contact and there's no cold solder connections. Replace it if so and if the problem persists move onto your board.

Does that magnet coil that controls the gate get a diode? I don't think I saw one on it.

I haven't played that game in ages, but I recall it being pretty fun.
Congrats.

Bad advice
I popped the hood and there's no diode on that coil. Only the 3 wires (2 striped wires on the right connection, 1 on the left). Sorry about that.
