Solved Playfield Illumination: Q/T Relay Clarification (gottlieb)

[cass2024]

Hello Pinballers,

I'm working on a 1980s Gottlieb Panthera. See: https://pinballnirvana.com/forums/threads/panthera-revival-an-electronics-rebuild-project.23249/

All lighting has been changed to LEDs, so working off of +5VDC for all lights. The Q and T Relays are being wired up so I'm hoping for some clarification on Illumination designation for the T Relay.

Are the "Playboard Illumination" lights (highlighted on schem) the CPU controlled lights in the game? My thought was that when the T Relay is opened, it cuts the power supplied to the CPU controlled lights (sorry bit of a pinball noob). But what's tripping me up is that the schematic says A7J5-1 is +5VDC and powers the CPU lights, whereas AC voltage A7J5-11 (6.3VAC) is supplying lights for pop bumpers, rollovers, playboard illumination and the hole light. So which is the Playfield Illumination I should be connecting to the N/C T relay?

Note that I haven't been able to familiarize myself with the AC voltages from the original machine as we inherited a machine that had no A/C for lighting.

Ok, I seem to have discovered the problem...

+6VAC is used for general illumination. As a pinball noob I wasn't sure which lights turn off when a tilt occurs.

It appears that the CPU controlled lights also turn off on a tilt, as wire (255) has it's ground cut upon it's leaf contact opening on tilt...
Is this something experienced pinballers can confirm?
