Quoted from Gcoco35:Sorry it's a 1994 gottleib rescue 911 machine. When I turn off tournament mode I see the credit 0 instead of free play on the screen. Coin ops are clean. It's like the coins are being redirected instead of falling all the way down to the collector.
If the mechs are rejecting quarters, they might not be quarter mechs. Or, they may be too worn out to direct coins in the proper direction.
can you post photos? Maybe there's something we can spot.
