help wiring turn signals

[lonnyjones]

i am putting signals on my bobber, my problem is this..

1.positive wire to "flasher" then other flasher wire to signal switch
2. then positive right from switch to right turn light
3. then left positive from switch to left turn light.
everything works like this

that is simple basic...now the problem is this cool speedometer i want to use.
it is small and has a single light for "blinkers" so it has one positive and one negative wire
for the "blinker" indicator. if i connect the speedo positive wire between flasher and switch it blinks with right or left as it should...but when switch is in middle and turn signals off the blinker light on speedometer stays on solid....
how do i wire so it flashes with signals but stays off when there is no signal?

My first thought would be hooking a diode onto each of the turn signal outputs and connect the "downstream" side of the diode to the speedo positive wire.

LED bulb or regular incandescent?

What year bike? Stock handle bar switches?
You probably know this, but for the use of otheres:
On a stock '81, for example, the brown wire comes out of the main ignition switch.
Then starts it's splits, like to the reg/rec, stator, but then it goes to a fuse.
From the 10a fuse, out of the panel, it goes into the flasher unit.
Then the br/w wire goes from the flasher unit to the handlebar switch.
Then out of the handlebar switch is the chocolate (left) signal and the dark green (right) signal.
They go to the front and rear signals.
There are 2 leads, one to dg and one to ch, that come from the signal wires and both join the dash indicator light.
So basically there are two wires coming out of the one dash light and each wire connects to one of the signal wires.
Now that is for a stock bike, but it might be helpful.

BTW, which flasher relay are you using? Jayel raises a good point, and if you're using LED's, you'll need a relay that will flash that small of load. Here's a crude diagram of what I was referring to. Sorry, it's crappy in Paint. Good software is at work.

hope this loads a crappy paint idea..
they are reg incan lights with reg auto flasher..
i did think there must be a diode way of doing this..
if i go to radio shack would they know what diodes i would use?

my bike is not stock, i got rid of wiring harness and made my own.
i just decided to put two turn signals on the back for safety.
they are little and use incan lights.
the flasher is a reg 2 post automotive flasher
the switch is a simple switch on handlebar...not stock..
how do you post pictures?

 

[lonnyjones]

thanks, this is what i thought I would have to do...but what kind of diodes?
i am gifted with a wrench and some wiring but diodes? all i know is the bands tell you size
and they work like a gate letting power go only one way...
is there a certain size i need?

i am a newb....lol

These are the diodes I used for my setup. There are others but these are nice and beefy. The end with the stripe is the "out" side of the diode and would go towards your single indicator. Wire it like the diagram above (kvanderploeg) and ground the other lead of the indicator bulb.

+1 to kvanderploeg. That is exactly what I did with my speedo from dime city and it works like a champ.

watching this for my own use too

 

[lonnyjones]

thank you guys very much..
i did not know what diode to use..
will pick them up today...they say they have them in stock at my radio shack..
thanks again

Good to know. I guess I will have to pick up a pack of the now..
