Hey guys, been having a lot of issues with my pro Football just going to list them out on here
1) Currently the right flipper(s) are dead but it still launches the ball still
2)When playing the game it skips a ball count so if I drain a ball on ball one instead of going to ball two it’ll go to ball three or ball four and it does it with each ball
3)Have to manually put games on it as it is set on free play but won’t give free games with scores or start regularly
4) the 1000 “points when lit bumper” keep turning off for long amounts of time which it didn’t start doing until recently
Thanks!

If anyone can help with just one of these issues that would be great

On my Big Hit, which might be similar to Pro Football, when the ball is shot into the playfield, the ball return switch opens which de-energizes the “Q” relay and completes the circuit from the flipper switches to the flipper coils. If you can find that relay, check that it de-energizes when the ball shoots and also check the switches. Good luck.

Thanks I’ll give it a shot

In my (brief) experience working on these EMs so far, I find it usually best and advisable to pick one problem to focus on and go from there.

Here are a few quick thoughts since I've been working on a Pro Football recently as well.

Quoted from Metalmanmiles:

1) Currently the right flipper(s) are dead but it still launches the ball still

The flippers are dead during game play as well? Try checking the Q relay, there is a normally closed switch that must be closed for the right flippers to fire. However the ball shooter coil does not require this closed switch, hence why it can still launch the ball.

Quoted from Metalmanmiles:

2)When playing the game it skips a ball count so if I drain a ball on ball one instead of going to ball two it’ll go to ball three or ball four and it does it with each ball

Check the normally closed switch on the AB relay. Mine was not making solid contact so would sporadically do this as well. This switch must be closed for the P, O and ball count unit relays to fire, although poor contact seems to have caused it to fire twice in some instances.

Q relay also plays a role in the ball counting sequence, and it seems that a few other issues might be hinting towards this relay as well.

Quoted from Metalmanmiles:

3)Have to manually put games on it as it is set on free play but won’t give free games with scores or start regularly

How are you manually adding games, via the coin chute switch? How is your free play set, by closing the switches on the credit reel? Can you elaborate on "not start regularly"? Might be worth investigating the startup sequence to see where you might be going wrong here.

Quoted from Metalmanmiles:

4) the 1000 “points when lit bumper” keep turning off for long amounts of time which it didn’t start doing until recently

This is normal, the pop bumpers are only lit occasionally during game play, and scoring the 1000 points will unlight them. I think it is on a kind of alternating relay that controls this.

Do you have the schematics for this game? Getting a copy of the schematics as well as instructions with the startup sequence listed has proven invaluable for me in troubleshooting my Pro Football, and easily worth the investment.

EDIT: rereading this a bit, it sounds like the Q relay is a great place to start.

Thanks for all of that, but before I can get into anything do you know where the Q relay is?

I did restore a 'Pro Football' many years ago and I took alot of pictures of the resto. I no longer have the machine as it was gifted to my daughter who still has the machine. Attached is a pic of the 'Relay Banks' for you reference, and a couple of resto pics.

So we got the right flipper working as we messed with the Q Relay a bit. But now it will not launch and it still skips games. When I bought the game it was set on free play but now I have to put each game on from the coin door, what would I need to do next to get the ball launching?

anyone else have any ideas on how to go about this? Have cleaned just about every relay.

Quoted from Metalmanmiles:

it will not launch

If the Ball Shooter coil doesn't activate and the motor runs, Inspect and diagnose this circuit with Alligator clip jumper wires

How was free play set? By connecting the switches on the credit reel, or in some other fashion?

When working on EMs, pick one problem to work on systematically. Randomly adjusting switches can often create more problems than solve them.

howardr has some great advice, work through that circuit to see if there are any issues.
