Relays
This week in class we coved basic relays relays van be used for switching between dips to high beam on the headlight circuit.
We used a 5 pin relay 86 and 85 are the control side of the relay and 30, 87, 87a is used for switching which carry higher amps.
readings
Circuit off | Circuit on |
86 13v | 86 13v |
85 13v | 85 0v |
30 13v | 30 13v |
87a 13v | 87 0v |
87 0v | 87a 13v |
86. There was available voltage on the point 86 because it is the input.
85. There was a 13v volt drop on 85 because the voltage was consumed when the switch was closed
30. There is a 13v available voltage because it is again the input positive.
87a.There is 13v in 87a because the circuit is off and the magnetic coil is not magnetized to pull the switch to 87. This could be the dip lights engaged.
87. Now 87 is 0v because the circuit is on and the magnetic coil is magnetized and it pulled the switch to 87 to complete the circuit. This could be now switched to high beam
