Pretty sure it was caused by replacing a bad coil with a brand new replacement coil that turned out to be bad as well.

History: Game was working fine and then GAR drops stopped resetting. Fixed a lose wire in target assembly. All good. Then, a few days later had fluttering right flipper. Could see coil wires in middle lug had separated from lug and so I ordered two new replacement coils. Switched bad coil to one of the new ones and game was working again. A day or two later I encountered the issue with the right flipper causing “Gorgar” to be spoken each time I released the flipper button. Spent way too much time diagnosing the target assemblies, boards, and looking for possible spilled solder on the wires. Finally, I thought could this be a problem with the brand new coil as I was desperate. Switched to the other new flipper coil and now game is working again. Two days later, and still working, but I am not yet past the “nervous” stage.

Have 2 very nice examples. I wound up with 5 and sold 3.

Having a weird issue with my Gorgar. First, everything tests perfectly. All switches and lamps behaving as they should in test mode. However, when I start a game there will be lamps randomly lit, and turning on and off. The lamps that are lit don't correspond at all to what I know should be happening. Scoring and sounds seem fine though. This behavior seems to correlate with heat -- when i first fire up a game it seems normal, but after it's been on a while it starts acting bizarro.

I should note that the MPU had pretty substantial alkaline damage when I purchased it. I went through it pretty deeply, removed all corroded parts, cleaned up traces, neutralized, ect. all sockets were replaced, as was the 40pin. I do recall the legs on some of the chips being very black. I cleaned them off, but I wonder if they were damaged? I don't remember which chips it was unfortunately.

Edit: Created a separate thread on this issue if you want to chime in there. Thanks https://pinside.com/pinball/forum/topic/gorgar-strange-controlled-lamp-issue#post-6469583

STRANGE PROBLEM WITH GORGAR EGO...
He keeps telling me his name is "Gorgar".
A few days ago I did the following work (a) replaced the right flipper coil (b) re-soldered two of the wires on the lower (Gar) target board as the game was not resetting the 3 targets when completed. Yes, I did all this with the machine off!
The game worked fine for a few days.
Now, just about every time I engage the right flipper, button, the game says "Gorgar" like it does when both target sets have been completed. However, the game plays fine in all other respects including the right flipper working fine and both target sets scoring and resetting properly. I am just getting quite annoyed by Gorgar's constant shouting of his name out loud during game play!
So, I am at a loss as to the cause of this. Not sure whether this is a problem with one of the target assemblies, crossed wiring of the flipper wires with target wires (possibly initiated by sloppy solder droppings while working on the coil or GAR targets) , an issue with connections into a specific board in the backbox, a specific board that has an issue with drivers or something else?
Any guidance as to how to proceed and what to check on would be appreciated. Thanks.

It's likely the driver board is signalling the sound board whenever there is a power fluctuation. Check the gaps on the leaf switches for the right flipper to ensure optimal play. Also replace the two diodes on the flipper coil. Make sure you put the new ones in the same orientation as the old ones. Diodes prevent electricity flowing back into the transistors on the driver board when the coil is released.
