I hate asking this...but I lost my Radio Shack "engineers book" or whatever it was called years ago. I used to be able to recite this stuff off the top of my head...but I think I must have drowned those brain cells  I've got a momentary pushbutton switch. I want to wire up a lighting circuit on my Uly. What do I need - and schematics / part numbers / tech talk are perfectly acceptable - in order to let this momentary switch turn a 12v circuit on with one push/contact, and off with a second push? | ||

Latching relay sounds like what you want:
Here's a way to make your own:

Perfect! Thank you  | ||

Speaking of that book, I know what it is, I have seen it on Mythbusters, what is it called? I need to order one. | ||
| Ratbuell |
I wanna say it was "engineers mini-notebook" or something similar. It was a RadioCrack...er, Shack publication IIRC. Mythbusters. Where'd I go wrong with my career choice? *I* should be doing that for a living! | ||

Ah, found it from Google http://www.amazon.com/gp/product//1885071337/ref=c m_aya_asin.title/103-5718971-3362230?ie=UTF8
I am calling BS there, I have gotten Buell wiring diagrams off the web on a moments notice before  Is that the same book you were talking about Rat? If not, it sounds like it would be good to have anyway. | ||

If you want the electronics to be all low power, you can use a flip flop, driving the base of a transistor, that runs the relay coil. http://en.wikipedia.org/wiki/Flip-flop_%28electron ics%29 | ||

Frog - that's close, but I want to say mine was maybe 3x5", green cover and spiral bound. More like a recipe book. 'course, at my age....that was a lifetime ago in publishing (and electrical engineering) terms LOL. Reep - what I'm looking to do is use a momentary switch to latch on (turn on) a lighting set. I'll be running all LED's (trying to conceptualize a hazard setup for the Uly with some TIR3 cop lights), so low-draw...but all 12v. | ||

Joe I remember the books, maybe that says something about my age! 'The Shack' is pretty much Radio Crap these days. If you had the lo-hi wired (on a ignition hot circuit) together you might consider stealing the 'real' hi-beam circuit for your aux. I'd use the flash-to-pass to trigger(and latch) the relay (and latch). There aren't enough discrete wiring stock but a few more wires shouldn't be too much trouble. Once latched though, the only way to de-energize the latched relay is to bring it back to 'low beam'. This assumes a separate blinker for the hazards and that you're ok with wiring lo-hi together. One relay and a few wires to bust out the flash circuit. Alternatively you could power the flash-to-pass switch (and relay) from low-beam and toggle to high to reset your hazards. | ||

Nah. Already got a dedicated switch - got a pursuit pushbutton from an XP Mounts to the master cylinder clamp bolts, sits at the RH thumb, and the pigtail goes to the flyscreen where I need to make my connections. I'll probably just extend back to under-seat, and put the relay(s) either under-seat or under-tail (between taillight and license plate). | ||
| Reepicheep |
In that case, you can probably drive the LED's off a bigger transistor. I'll try and do some math tomorrow and see what I can work up... | ||

gotcha, just seems like a 4 or 5 relay approach is a bit much. Latching is easy, the reset bit without a bunch of other relays gets tricky. Consider reset with ignition off? No added relays that way. | ||

This relay would do it: http://www.newark.com/magnecraft/711xbxcl-12d/alternating-load-relay/dp/10M6472 I got all those old 'Shack books  | ||
| Sekalilgai |
neat! I learned something new...I was only aware of the latching with reverse polarity toggle type. | ||

My head is flip floppin with semicoinductors! I have a hopeful idea, but No Uly wiring diagram here to confirm my hopes! On a BMW you could push the turn signal cancel switch to produce your flipflop ground pulse! Does a ULY have is a turn signal cancel switch that sends a ground back to blinker circuit? If Yes! take a peek at the AUTOSWITCH 4NB http://www.autoswitch.com/as4nb-Install.htm Sorry if this turns out to be a wild goose chase. | ||

The turn signal cancel button is mechanical. Try it when the bike is off. Perhaps the flash to pass trigger can be hijacked away from the high beam? | ||
| Go2 |
Can anyone round up a wiring diagram for me to look at? I want to use exsisting switches to trigger external relays for lights, garage door opener, whatever. tnx | ||

What year is your Uly? | ||

Ronmold, I own a 2007 xb12x. j |
