The INDY lamps at the top of the playfield have gone dim (or barely flashing all at the same time very dimly) suddenly so you cant tell which lanes have been triggered already to get the X bonus.
I've checked the socket and the plug connected to the lamp circuit board and it seems to be secure. I guess the fact that the lamps are still getting power indicates that there is an issue somewhere further down the circuit.
Any ideas where I can look?
ps... take a look at the pics of the playfield mods I have added to my machine. The crystal skull was about $20 and the tank was about $30, found them both on eBay. The Ark I found for about $20 on Amazon. They add a nice touch to the Indy Adventure theme don't you think!?
