1.

Let the engine run (2,000 r/min), and check the printed heater
with the battery fully charged.

2.

With  the  defogger  switch  "ON,"  use  the  circuit  tester  to
measure the voltage of each printed heater at the rear window
glass  center  A  point.  If  approximately  6  V  is  indicated,  it  is
judged good.

3.

If the voltage of 12 V is indicated at the A point, there is an
open  circuit  between  the  A  point  and  negative  terminal.
Therefore, by moving the test bar slowly to the negative side,
search and determine the location where the voltage changes
suddenly (0 V). The location of voltage change indicates the
open circuit position.

4.

Also, if the voltage indicates 0 V at the A point, there is an open
circuit between the A point and positive terminal. Therefore,
search and determine the location of voltage change (12 V)
using the above mentioned method.
