Flasher connections

1. Open the coin door and go to Settings → Diag → Lamps → Flash.
2. Cycle with the volume or flipper buttons. The machine shows each flasher’s number, location and factory wire colours as you go.
3. On most Sterns the flasher wires are orange and red. The GI trigger (Blue/White cable) can be any white GI bulb — usually a yellow wire on a Stern.

The Red/Green UV+Glow cable goes on a flasher, never a GI bulb. GI is on constantly, so on GI the UV+Glow never rests — it runs very warm and can damage the light bars or module. If a flasher is not listed below, do not guess at one.
