Troubleshooting
10Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Lamp(s) do not light up | Is circuit breaker switched to the 'ON' position? Switch circuit breaker 'ON'. Do lamps appear to be broken, black or burnt? Replace lamps. Do lamps flicker but fail to fully illuminate? Check engine RPM (See Section 1.12). Do lamps fully illuminate but randomly quit working? Check engine RPM (See Section 1.12). Is engine RPM correct? Re-set engine RPM (See Section 1.12). | |
| Input voltage to main circuit breaker 120 V (± 10 %) per leg | NO | Replace main circuit breaker |
| Output voltage from main circuit breaker 120 V (± 10 %) per leg | NO | |
| Input voltage to each lamp circuit breaker 120 V (±10%) | NO | Repair or replace wiring from main breaker |
| Output voltage from each lamp circuit breaker 120 V (±10%) | NO | Replace lamp circuit breaker(s) |
| Input voltage to ballast capacitor(s) 400 V (±10%) | NO | Check input voltage at ballast capacitor(s). NOTE: Disconnect capacitor output lead before checking capacitor input or output voltage readings. |
| Output voltage from ballast capacitor(s) 400 V (±10%) | NO | Replace ballast capacitor(s) |
| Tower wiring for cuts or shorts, check continuity of tower wiring from capacitors to light bar, remove lamp(s) and check continuity of wiring from light bar to each lamp socket | NO | Repair or replace damaged wiring. |
| Input voltage to each ballast transformer 120V (±10%) | NO | Check wiring from lamp circuit breakers to ballast transformers. Input voltage to each ballast transformer should be (120V ±10%). Check output voltage from each ballast transformer and wiring to ballast capacitor. Output voltage should be 400 V (±10%). |
| Ballast transformer input and output voltages in range | NO | Repair or replace damaged wiring. |
