Testing & Diagnosis: Amplifier
- If lights do not turn on automatically, and photocell and switch tests are positive, remove amplifier from heater plenum chamber flange and disconnect multiple connector. Connect a jumper wire from red wire to light blue wire in connector on body wiring side. If lights now turn on, replace amplifier.
- If lights do not turn off automatically, and photocell and switch tests are positive, disconnect multiple connector at amplifier. If lights now go off, replace amplifier.
- If lights fail to turn off automatically when ignition is turned off, or lights turn off immediately regardless of time control setting on switch, check system with amplifier known to be good. If lights operate properly, replace original amplifier.
