~onnected in the exact same position. Place your
ohnuneter leads on the terminals SG and C as shown
and read the meter. Then reverSe the ohmmeter leads and
again read the meter.
In one direction, the ohm reading will be 100 ohms
g.r
less.
In the other direction, there should be no ohm reading. Any
value above 100 ohms indicates a faulty igniter. Any ohm
value found with
the
meter conections in either direction, the
igniter is faulty.
