vw used a number of differentschemes over the years on bothbeetles and busses. this articleexplores some of the more commonaspects of the circuits.basicsthis diagram shows the turn signalflasher circuit in its simplest form:later, the 4-terminal flasher relay wasreplaced with a somewhat simpler 3-terminal design.externally, the only difference is inthe connection for the dash indicator.the flasher receives power from oneof 2 fuses, depending on whether ornot the hazard switch is operated.the same flasher is used for bothturn indicator and hazard functions.internal circuitry in the flasher keepsa small "sense" voltage on terminal #49a all the time. when the indicatorstalk is pulled to left or right, theindicator bulbs on that side areconnected to terminal #49a and loadthe flasher circuit so that it knows tobegin flashing. immediately, theinternal relay contact closes from (+)to #49a and the bulbs light. theflasher electronic circuit then turnsthe relay off and on to provide theflashing cycle.
