Having some odd issues with an Elvis that I just picked up. So far this has happened twice. During the game, a ball will drain, flippers die, and the game continues. It will show the next ball and the display and sounds keep going, but no ball gets kicked out, flippers remain dead, and lights stay on.

The first time it happened, I just shut it down and restarted it. No issues, second time it happened I went into the test menus, and checked tech alerts, it showed all ok. I went through some of the tests, and found some GI comes on with flippers and some multiple lights are coming on during single light testing.

These are not on the same circuits. And there is currently a new Rootendog driver board installed by the previous owner. Not sure if that would be the culprit. Voltages appear to be normal.

Yes, I'll get one in the next day or so.

Batteries and battery hold have alkaline damage. I've removed the holder and cleaned the holes. NVRAM should be here Monday. Looking over the rest of the board, I don't think the damage spread.

Alright here's some pics:

Will update when the NVRAM is installed.

Installed NVRAM today. Played about a dozen games, power dipped on the second game, and lost all power to solenoids for a few seconds but they came back. Will keep an eye on it.

Symptoms are back. Played for about an hour, all solenoids died several times. Will be trying to borrow a driver board locally, and go from there.

All settings reset after I installed the NVRAM. But when the solenoids die, the game keeps playing. All voltage LEDs remain lit except one, which is unmarked.

Will try that tonight and see what comes up.

That was a bust. Coil testing everything passed, when I went individually, and then when I went to cycle, everything died. So I thought it was in a coil, checked tech alerts, system came up ok, went back into to coil test cycle, and they all worked. Tested flashers, found one burnt out, replaced, no change.

May have a driver to test over the weekend. I did notice the LED in the center of the Rottendog goes out, but this LED isn't marked, other than test point three. I use it to test the voltages on the other test points, and my 50V is reading 78V right now, both with and without the LED being on. Is there a way to adjust the voltages? I'm wondering if the high voltages is causing the issue.

90% sure it's a Stern driver board. Will know more on Friday or Saturday when I pick it up.

Was able to get a Stern driver board. Ran it for four hours last night, no issues.
