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
The condenser does not pass D.C. current, but
as the number of waves increases when it
passes A.C. current, impedance (resistance
l
l
against A.C.) decreases, and current flow is
facilitated. A noise suppressing condenser
which takes advantage of this property is in-
serted 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 in-
serted into the power line for the noise source,
and works by preventing the noise component
from flowing or radiating out of the line.
