TROUBLESHOOTING
If you are having problems after installation follow the Troubleshooting procedures below.
Procedure 1:
Check the device for proper connections.
Verify that POWER LED is on. If POWER LED is on skip to Step 3, if not continue.
1. Check the fuse of the device or the external fuse on battery positive cable. Replace if necessary.
2. Verify that Ground connection is connected to clean metal on the vehicle's chassis. Repair/replace if necessary.
3. Verify there is 9 to 16 Volts present at the positive battery and remote turn-on cable.Verify quality connections for both cables at device,
headunit and battery/fuseholder. Repair/replace if necessary.
Procedure 2:
PROTECTION LED is on.
1. If the PROTECTION LED is on, this is a sign of of driving the device at very high power levels without adequate airflow around the device.
Shut off the system and allow device to cool down. Check that the vehicle charging system is maintaining proper voltage. If the previous items do not
solve the problem, a fault may be in the device.
Procedure 3:
Check the device for a proper audio signal.
1. Verify good RCA input connections at headunit and device. Check entire length of cables for kinks, splices, etc.
Test RCA inputs for AC volts with stereo on. Repair/replace if necessary.
Procedure 4:
Check the device for a popping noise while turning on.
1. Disconnect input signal to device and turn device on and off.
2. If the noise is eliminated, connect the REMOTE lead of device to source unit with a delay turn-on module.
OR
1. Use a different 12 Volt source for REMOTE lead of the device (i.e. battery direct).
2. If the noise is eliminated, use a relay to isolate the device from noisy turn-on output.
Procedure 5:
Check the device if you experience excess Engine Noise.
1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.
OR
2. Bypass any and all electrical components between the headunit and the device. Connect unit
directly to input of the device. If noise goes away the unit being bypassed is the cause of the noise.
OR
3. Remove existing ground wires for all electrical components. Reground wires to different locations.
Verify that grounding location is clean, shiny metal free of paint, rust etc.
OR
4. Add secondary ground cable from negative battery terminal to the chassis metal or engine block of vehicle.
OR
5. Have alternator and battery load tested by your mechanic.Verify good working order of vehicle electrical system including distributor,
spark plugs, spark plug wires, voltage regulator etc.
