Bill_on_a_bike Posted August 23, 2009 Share Posted August 23, 2009 Always wonderd this, what's the circuit behind indicators flashing? How would you set it up, stand alone?cant find any answered on google atall.Just plain curiosity. Quote Link to comment Share on other sites More sharing options...
iWannaGoFast Posted August 23, 2009 Share Posted August 23, 2009 I'm not in the slightest an electrical buff, but i guess it's just a simple on/off switch routed through a timer. Quote Link to comment Share on other sites More sharing options...
Stu Posted August 23, 2009 Share Posted August 23, 2009 its through a flasher relay the way it works is electricity passing through it heating an element up that flexes making a contact then it cools quickly breaking the contact then repeats the cycle thats the short version Quote Link to comment Share on other sites More sharing options...

Voodoo Posted August 23, 2009 Share Posted August 23, 2009 Should get yourself a modern bike Stu, you just flick a switch on mine! Quote Link to comment Share on other sites More sharing options...
Bogof Posted August 24, 2009 Share Posted August 24, 2009 its through a flasher relay the way it works is electricity passing through it heating an element up that flexes making a contact then it cools quickly breaking the contact then repeats the cycle Unless they are electronic, and not electro-mechanical. If it is electronic, it'll look something like this...http://www.instructables.com/files/deriv/F27/PSVZ/FTY4CNCR/F27PSVZFTY4CNCR.MEDIUM.jpgI'll let Stu explain how that works, cos I haven't a clue Quote Link to comment Share on other sites More sharing options...
Bill_on_a_bike Posted August 24, 2009 Author Share Posted August 24, 2009 Well a 555 timing chip is a complicated piece of kit, overkill for indicators.Stu's explanation makes sence, and if he's a nerd then i'm a super geek for asking the question.Still not quite clear on why all flasher relays i've bought only have 2 terminals Quote Link to comment Share on other sites More sharing options...
Guest Posted August 24, 2009 Share Posted August 24, 2009 in and out, a positive signal goes in and the resistance causes a switch to move, when the switch makes contact the resistance drops and the switch reverts to the off position.. starting the cycle all over again.. so in essence you have 2 switches in the same circuit.. the one at the bar decides left and right, the other (flasher unit) sorts out the flash.. if either fails no flash.. this is why LEDS flash to fast, as the resistance of the bulb is less so builds in the flasher box quicker..yes' i'm a sparky....by hobby..

Guest Mr Miller Posted August 24, 2009 Share Posted August 24, 2009 "How do indicators flash?".................usually just on and off......I'd go with Frankie's explanation! Quote Link to comment Share on other sites More sharing options...
