Relays P5 and P6 are used to turn on the headlights (see subsection 12.10) type 113. 3747 mounted in a mounting block. The same relays are used to turn on the heated rear window.
Relay switch-on voltage at temperature (23±5) °С is not more than 8 V, and the winding resistance is (85±8,5) Ohm at 200°C.
Instead of relay 113.3747, you can use new interchangeable relays of type 90.3747-11 with a plastic cover and slightly larger dimensions. And instead of the relay 113.3747-10, which have a mounting bracket on the cover, you can use the relay 90.3747-10 (with bracket). The characteristics of the new relays are the same as for relay type 113.3747.
Relays of type 902.3747-11 are also available (without bracket) and 902.3747-10 (with bracket). These relays are mainly used on cars with fuel injection systems and are distinguished by the addition of an interference suppression resistor, which is connected in parallel with the relay winding. These relays have resistance between terminals "85" And "86" is (72±8) Ohm. These relays can also be used instead of relay type 113.3747.
