TROUBLE SHOOTING
If you are having problems after installation follow the procedures below.
Procedure 1:
Check the device for proper connections.
Verify that POWER LED is on. If POWER LED is on skip to procedure 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, head unit and battery/fuse holder. Repair/replace if necessary.
Procedure 2:
PROTECT LED is on.
1. If the PROTECT LED is on, this is a sign 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 head unit 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.
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 head unit 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. 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.
