Motorcycle Flasher Relay Circuit Diagram - Wiring Diagram - The dash speedo indicator bulb used with the three-terminal flasher relay is hooked up from the ( ) deliver to #49a and it flashes opposite to the flip indicator bulbs. ?for example, while the turn indicator bulbs are lit, there may be 12v present at #49a. That means that both sides of the dash bulb have 12v on them and no modern-day can glide thru the bulb. ?. This association was also used on (us) busses all of the way through the 1971 model. ?simplest in '72 did america bus get separate prevent and flip bulbs. ? click on right here for the '68 through '71 bus wiring (very similar to above).
The only difference in circuit operation for risks is that the flasher gets strength from the second one fuse, which is live whether or not or now not the ignition is switched on or not. The hazard transfer has every other set of contacts (now not shown here) which connects each left and right units of bulbs to the flasher. Now we could flip to the turn sign machine used on early vehicles. ?from the mid 50's through 1961, motors which did not have semaphores used the prevent lighting to double because the rear turn indicators. ?to do that, a unique flip signal switch with 6 wires instead of the later three-wire design changed into used. ?this switch had to path the flasher output to the brake mild getting used for turn indication whilst leaving the final brake light to feature from the stop mild transfer. ?the circuit looks like this:.
Internal circuitry inside the flasher keeps a small "sense" voltage on terminal #49a all the time. While the indicator stalk is pulled to left or proper, the indicator bulbs on that facet are linked to terminal #49a and load the flasher circuit so that it knows to begin flashing. Straight away, the inner relay contact closes from ( ) to #49a and the bulbs light. The flasher electronic circuit then turns the relay off and on to offer the flashing cycle. Later beetles and busses which had separate stop and turn lamps within the rear used a highly simple hazard transfer association. ?i've drawn it here in a form which shows the mechanical functioning of the switch contacts.
