I am bringing a Gottlieb Genesis back to life.

I am having a problem with getting the row of 67 bulbs to light up.

I have never seen them come up during play. On both games I have had.

I found the 2 AUX driver boards. One for the Lights around the robot the other for the string of lights above the boards in the back box

What triggers the AUX driver board?

I have 5v at the connector and I see ground goes threw a relay.

We're is the LAMP RELAY ( LIGHT BOX) located?

There's a relay under the playfield that activates them. Additionally, power passes through a large 7W resistor under the playfield, and those are sometimes a source of problems.

I see the pf lamp relay on the left side as you have the pf up ...we're is the light box relay?

Dose the light box and the robot lights share the same relay?

I am having the same issue did you ever get it solved or at least find some kind of answer, I have 5 volt for the swt at that relay power to the lights but nothing from the aux boards and they appear to be working when I swap them out into another machine. and the 7watt resister, where is that if that's the one of the 3 concrete ones off to the far right almost directly across from the relay mine are all 4 watt maybe that's it anyway any insight would sure help. It is a minor issue but I hate it when things don't work.

Same problem on my Genesis as well. Doesn't seem like any progress has been made. I've been restoring a Genesis over the past couple weeks and this is one of my last check-boxes. I'm going to look at some of the things suggested here and report back. I don't want to revive a zombie thread, but this seems to be the exact problem that I've got.
