Headlights On Too Late, Off Too Early

With ignition and lights turned off, cover photocell to block out light. Check resistance between terminals "J" and "L" on amplifier connector, with time delay in any on position. Record resistance reading. Adjust control adjustment screw on amplifier until resistance reading is 1/2 of previous reading. If amplifier has been previously adjusted, set resistance to 4100-4500 ohms.
