Examination
1. Checking the heater relay.
- A) Check for continuity between terminals "1" And "3".
- b) Check for continuity between terminals "2" And "4".
- V) Check for continuity between terminals only "4" And "5" relay when battery voltage is applied to the terminals "1" And "3".
2. Checking the electromagnetic clutch relay.
- A) Check for continuity between terminals "1" And "2".
- b) Check for continuity between terminals "3" And "5" relay when battery voltage is applied to the terminals "1" And "2".
3. Check fan relay #1.
- A) Check for continuity between terminals "1" And "2".
- b) Check for continuity between terminals "3" And "4".
- V) Check for continuity between terminals only "3" And "4" relay when battery voltage is applied to the terminals "1" And "2".
4. Check relay #2 fan.
- A) Check for continuity between terminals "1" And "2".
- b) Check for continuity between terminals "3" And "4".
- V) Check for continuity between terminals only "3" And "5" relay when battery voltage is applied to terminals *1" And "2".
5. Checking relay No. 3 of the fan is carried out similarly to checking the relay of the electromagnetic clutch.
