I am still working through some issues with Elvira. The game was not awarding extra balls for some reason even though all of the settings seemed to allow it.

I did a factory reset and after powering back up, all of the coils fire at the same time, the GI lights come on and then the displays are blank.

I pulled the batteries for 30 minutes and tried it again, but the same thing happens.

Can the ROMS be bad or does it seem like something else?

Thanks

Update;

Still troubleshooting. Replaced the F4 fuse (bad) on the power supply. powered up again and fuse F4 and F5 started glowing and before I could turn it back off F5 had already blown.

This is weird because I haven't changed anything except resetting to factory settings.

More update: I think it is unrelated to the factory reset. The main power supply is blowing F4 and F5 without anything even connected to it, so it must be a short in the power supply.

I may have the parts to fix it if it is one of the same parts as a Williams system 11.

More Update: PinRepair says it is BR1. I think I have one. I will try to fix it sometime tomorrow.

It was the bridge. Bridge tested bad. Replaced bridge and all the caps. Working great now.
