Delay Control Test
- Using an ohmmeter, check resistance between Purple/Orange and Dark Blue/Orange wires of photocell/amplifier connector. See Fig 1
. With control in maximum "ON" position, reading should be approximately 200,000 ohms. If not, perform step 3) of POTENTIOMETER TEST below.
- If potentiometer is okay, check Dark Blue/Orange wire for continuity between potentiometer connector and amplifier connector. If not, replace potentiometer.
- If all systems check out okay, but system is still malfunctioning, replace the amplifier assembly.
