Testing & Diagnosis: Photocell
- Cover photocell with black cloth, start engine, and turn on system. If lights do not light within a few seconds, uncouple multiple connector at amplifier, then remove gray wire from connector to body wiring and recouple connector. If lights light, replace photocell and reinstall gray wire.
- If lights fail to turn off automatically with adequate outside lighting, shine a bright light into photocell window and rotate cap to centered position between "Early" and "Late". If lights turn off normally, cap may have been rotated so far that light through window in cap was blocked off. If lights remain on, check photocell by connecting jumper wire from gray wire to black wire at amplifier to complete photocell circuit. If lights now turn off, replace photocell.
