As in, does it matter what brand or part number? getting one soon for my system 3 Gottlieb Operation Thunder.

Also, will bad ram cause the resistor board to overheat? I traced the wiring from the resistor board to the 6116 ram installed. The A13 resistor board is scorched and gets super hot.

No - all 6264's are not the same.
There are several variations out there.
Some are 0.3" wide, some are 0.6" wide.
Some are slow speed but low power (for use in battery backup application)...and some are high speed but draw lots of power (not for battery backup application).

Resistor board connected to a 6116? Huh? I don't follow that one. Are you sure you traced the wiring to that one properly?

Yes, the 4 big resistors mounted on the back of the lightbox door. Looked that way on the schematics. I will have to get out the dmm and double check

Looked a little more closely at schematics.

From what I can tell, the resistor board has 20V coming in and a ground coming in. the 20v goes through two 33ohm 5watt resistors, the negative does the same, Going out two wires go straight to lights in the pop bumpers, two wires go out to the aux driver board (i think, schematics not in front of me) next to it with another set of wires piggybacked in that go down to the lights in the pop up bumper.

So the current problem, (apart from the game being dead and not booting up, LOL) is why is my resistor board burnt and toasty. And for all I know this is just a symptom of the game not booting up and not the cause. When I power up the game the resistors get hot.

Hopefully someone has some insight into this
