(b) The normally closed-type
When a normally closed relay as illustrated
here is checked, there should be continuity
between terminals 30 and 87 when the
relay is de-energized. There should be no
continuity between terminals 30 and 87
when battery voltage and ground are
applied to terminals 85 and 86. The relay
condition is determined by this check.
NOTE:
Check the relay in both conditions, i.e.
Energized and not energized.
(c) The NO NC (Changeover) type
It has 2 relay out pins. One will be in
contact in the changeover state as in NC
relay. When it is energized it brakes the NC
contact and connect the other output pins.
