Automotive Turn Signal Wiring Diagram - Now we could flip to the flip sign system used on early motors. ?from the mid 50's via 1961, cars which did now not have semaphores used the prevent lights to double because the rear flip indicators. ?to do this, a special turn signal switch with 6 wires rather than the later three-cord layout become used. ?this transfer needed to path the flasher output to the brake mild being used for turn indication while leaving the last brake light to feature from the forestall mild switch. ?the circuit looks as if this:.
This association turned into extensively utilized on (us) busses all of the way thru the 1971 version. ?best in 'seventy two did america bus get separate prevent and turn bulbs. ? click here for the 'sixty eight via '71 bus wiring (very similar to above).

The dash speedo indicator bulb used with the 3-terminal flasher relay is connected from the ( ) deliver to #49a and it flashes contrary to the flip indicator bulbs. ?for example, while the flip indicator bulbs are lit, there is 12v gift at #49a. Meaning that both aspects of the dash bulb have 12v on them and no current can flow through the bulb. ?.
Later beetles and busses which had separate forestall and flip lamps inside the rear used a highly easy hazard switch arrangement. ?i have drawn it here in a form which suggests the mechanical functioning of the transfer contacts.
Inner circuitry inside the flasher maintains a small "experience" voltage on terminal #49a all the time. Whilst the indicator stalk is pulled to left or proper, the indicator bulbs on that facet are connected to terminal #49a and load the flasher circuit in order that it is aware of to start flashing. Immediately, the inner relay contact closes from ( ) to #49a and the bulbs light. The flasher electronic circuit then turns the relay off and directly to provide the flashing cycle.
