"4M. Haunted House/Black Hole Lower PF Lights
On Haunted House and Black Hole, when the ball goes to the lower playfield, nine bright lights turn on to illuminate the lower PF. These are special 24 volt #313 lights, which run off the solenoid voltage. The 313 bulbs are not so easy to find, so here's a way to convert them to using standard #44 bulbs that run off 6 volts. (Actually I prefer to use #55 bulbs, but 44 bulbs work fine too.) The lighting with #44 or 55 bulbs won't be quite as bright as the 24 volt #313 bulbs, but it's really close. Both Tim Arnold and Steve Charland recommend this modification.
First you need to find the "L" relay, which energizes when the ball goes to the lower playfield. The L relay is located under the lower playfield. Now remove the orange-slate-slate wire (24 volts) from the L relay switch stack, and tape it off and wire wrap it away from the relay. Then jumper a wire to it's switch lug from the 6 volt DC controlled lighting power line (black-slate-slate). The 6 volt DC line is used at all the CPU controlled lights, so it's real easy to find this power line. Lastly replace all the original #313 lamps with #44 or #55 lamps. That's all there is to it! Note we don't use the 6 volt AC general illumination line because the 44 lamps won't be bright enough. "
I cannot find an L relay on hh, or in the manual, wtf?
