TB0335B Page 7 of 10 10/18/03 SERVICE This unit is designed to provide years of reliable service under even the worst conditions. Many times there may appear to be a problem with the unit when the true problem is in the speaker(s) or improper installation. The following chart shows typical symptoms and possible causes. A blown panel fuse(s) doesn't necessarily mean that the unit is bad. If a speaker or speaker lead is shorted this fuse will blow before the unit is damaged. Disconnect the SPKR leads and replace the fuse. If the siren emits a sound when in the Yelp position it is OK. Check the speaker(s) or leads for possible shorting. Note: Older versions of this amplifier unit used one 20AMP fuse to supply both internal amplifiers. This means that if one internal amplifier output is shorted and blows the fuse, the other internal amplifier will also lose power even though it may be fine. Be sure to check both amplifier unit outputs for shorted wiring or speaker. PROBLEMS Symptom Possible Cause Check No Power or siren output Power switch not turned on Bad Speaker Connector or connections loose Panel fuse(s) blown Loose connection at power source Does backlighting come on? Do you hear a “pop” when turned on? With siren on, yelp selected, listen for tone in amplifier. Is an external fuse or circuit breaker used? Are the power leads connected to a good buss? No siren tone – PA works High Voltage Protection Mic Button stuck The input voltage must be less than highest rating. Does Mic Button release properly? No PA PA volume not set properly Try turning the PA volume control. Distorted siren sound Speaker assembly loose Intermittent Aux Input connection Low Vehicle voltage Is the speaker bell or tip loose? Is the Aux Input used and wired properly? The input voltage must be greater than lowest rating. Intermittent siren tone High Voltage Protection Connector loose Loose connection at power source Mic Button activation Circuit breaker in supply connection Is the vehicle voltage regulator working properly? Is the connector tight on the back of the unit? Check for loose leads back to power source. Is something lying on the microphone? Is a circuit breaker used with at least 50A rating? Horn or manual stuck on Siren switch stuck Aux Input improperly connected Does the Siren pushbutton switch return fully when released? Is the Aux Input used and wired properly? No Radio Unit not connected to a radio Radio volume too low Is the radio connected properly to the unit? Can you hear the radio in the vehicle? Try adjusting the internal radio volume control.
