winker relay
winker relayCan anyone give me a laymans answer on how a winker relay works? Thanks Mike
Mike,
When the switch is activated, current flows through the winker bulbs and a bi-metal spring to energize the relay coil. That current heats up the spring causing it to break the contact to coil--the winker bulbs go off. With no current flowing through the spring any more, it cools down and bends back to its original position, re-establishing the connection to the relay coil. This cycle repeats itself until the handle-bar switch is put back in its neutral position. Wilf
relayThanks Wilf: So would I be correct in assuming that if one of the two bulbs (front and back) is bad there would be no action from the relay? Not as much current going through the relay?
Thanks Mike Yes, that's usually what happens--because there is only half the current, the bi-metal spring will take forever to heat up enough to break the circuit, so the bulb remains lit.
Also, if a blown bulb is replaced with a new one of a different wattage, the wink rate will either speed up or slow down as opposed to the standard 80 (?) winks per minute. That's the reason why LED winkers, such as I have on my Super Hawk, require a totally different winker relay. Wilf
relayThat clears it all up for me Thank you.... Glad I didn't opt for the more expensive relay when I ordered a new one. $5.95 mistake isn't too bad:) I guess I will put the original back in and wait for the bulbs to come.. Thanks again mike
Hi,
It took some time to understand the word Layman but I found it (not realy a laymans answer) : (thanks to wikipedia) As usual, things are more complicated then most people think (want), therefor a laymans anwer isn't solving your problem probably. Look at my explanation in the thread C77 winker in this section. The condenser, resistor and coil setup are determining the switching time. No bi-metal in there. Make sure the relay is wirered to ground, otherwise the relay won't work. Do you have the type with extra ground wire or without the ground wire ? again, see this thread : http://www.honda305.com/forums/viewtopi ... sc&start=0 regards, Jensen assembly of Japanese motorcycles requires great peace of mind (Pirsig)
