If he's got an Altek lamp board, no need for the adapters, they function the same way. (But thank you for the plug!)

First thing I'd check is that the extra wire on the altek board is clipped to the correct location. Should be attached to the voltage supply side of a controlled lamp, and you need around 5 volts where you're clipping in to.

Typically if all the lamps are dimly lit it means the wire is attached at the wrong spot, or not connected at all. So you end up having voltage back-feed from lamp to lamp via the anti-flicker resistors.

Quoted from Bradroback:

so Hans, you hit the nail on the head. the alltek board voltage lead was connected to the wrong circuit on the back box. i attached it to the beginning of a GI circuit that 'looked' like a feature circuit. i should have known this but i am at the tail end of a 70 hour total restoration on this thing and my brain is a little fried. thanks for the help!!

No worries at all. Some games it's pretty hard to tell the difference between GI and controlled lamps on the backbox panel.
