Sebring V6-2.5L SOHC 24 Valve (1996)
2. There is much noise only on FM
Due to differences in FM and AM systems, FM is not as susceptible as AM to interference from engines, power lines, lightning, etc. On the other
hand, there are cases due to the characteristics of FM waves of noise or distonion generated by typical noise interference (first fading and
multipath). See: Chart A-2 Noise Appears at Certain Places When Traveling (FM) <Noise (hissing) occurs in weak signal areas such as
mountainous regions, but this is not due to a problem with the radio.>

Chart A 6
There is noise when starting the engine.
CAUTION:
1. Connecting a high tension cable to the noise filter may destroy the noise filter and should never be done.
2. Check that there is no external noise. Since failure to do this may result in misdiagnosis due to inability to identify the noise source, this operation
must be performed.
3. Noise prevention should be performed by suppressing strong sources of noise step by step.
NOTE:
1. Condenser
The condenser does not pass D.C. current, but as the number of waves increases when it passes A.C. current, impedance (resistance against A.C.)
decreases, and current flow is facilitated. A noise suppressing condenser which takes advantage of this property is inserted between the power line
for the noise source and the ground. This suppresses noise by grounding the noise component (A.C. or pulse signal) to the body of the vehicle.
2. Coil
The coil passes D.C. current, but impedance rises as the number of waves increases relative to the A.C. current. A noise suppressing coil which
takes advantage of this property is inserted into the power line for the noise source, and works by preventing the noise component from flowing or
radiating out of the line.
