REMOVAL
Airflow Valve
Diode and capacitor on
CAUTION
S1 sensitive switch
Apply heat sink pliers to leads of diode when
unsoldering. Excessive heat will damage the
diode.
1.
Unsolder diode (1) from normally closed (NC)
and free normally open (NO) terminal on S1
sensitive switch.
2.
Unsolder capacitor (2) from normally closed
(NC) and from common (C) terminals on S1
sensitive switch.
INSTALLATION
1.
Cut and bend leads of diode (1) and capacitor
(2) using the old parts as a pattern.
CAUTION
Apply heat sink pliers to leads of diode when
soldering. Excessive heat will damage the
diode.
CAUTION
Diode must be connected properly or
damage will result. Observe the banded end
of the diode.
2.
Solder diode (1) leads to normally closed (NC)
and to normally open (NO) terminals on Si
sensitive switch. Ensure that banded end is
installed on NO terminal. Refer to wiring
diagram (p. 2-19).
3.
Solder capacitor (2) leads to normally closed
(NC) and common (C) terminals on S1 sensitive
switch. Refer to wiring diagram (p. 2-19).
4.
Coat electrical connections with oil varnish
(item 3, app C).
