2) Disconnect positive terminal from terminal "7" checking voltage
between terminal "6" and "5" of relay.
If measured voltage changes from battery voltage to about 0 V
2.7 to 4.6 seconds after disconnecting positive terminal from ter-
minal "7", relay is in good condition.
If not, replace relay.
[INT circuit]
1) Connect positive terminal of battery to terminals "1" of relay and
negative terminal to terminal "5" of relay. Then positive terminal
to terminal "3" of relay checking voltage between terminals "6"
and "5" of relay.
If measured voltage changes from about 0 V to battery voltage
when connecting positive terminal to terminal "3", relay is in
good condition.
If not, replace relay.
2) Connect positive terminal of battery to terminal "2" of relay, then
disconnect positive terminal from terminal "2" of relay checking
voltage between terminals "6" and "5" of relay.
If measured voltage changes from battery voltage to about 0 V
when disconnecting positive terminal from terminal "2" and
about 0 V to battery voltage 8 8 2 seconds after disconnecting
positive terminal from terminal "2", relay is in good condition.
If not, replace relay.
