Standalone Emergency flashers

[Figuarus]

Guys, I'm slowly getting Hotdog updated on a couple of fronts, but Im stuck at something that I've not been able to find a clear answer for.

I know some people have used the aftermarket turn signal/hazzard combo switch that clamps onto the steering column, and also some of you have managed to get a hold of a flarestat kit.


The problem I have, is that I'm kind of broke, but very resourceful.

I have a harness that came out of my 96 S10 blazer, and I have lots of wiring, a fuse panel, and most importantly, a few flashers.

The question is this. Can anyone provide me with a schematic on how a flasher system works? I know I should be able to add a simple toggle switch for my dash that allows me to essentially make my own system.


Can anyone help? I'll do a detailed write up after the fact...

[NVS-C10]

One on/off switch, two relays, and a no load flasher.. switch to no load flasher providing 12v +, then other end of no load flasher to the two relays 86, then 85 on relay to ground, then 12v + to 87 on relays, then turn signal switch side to 87 a on relay (make one relay left and one right).. last park lamp side to 30 on relay (again keep same left and right as used in prior step).

Sorry nvs, but do you have time and crayons to draw this out for me? I work better off diagrams.

Wish I could help but I was thinking the same. Thanks for the laugh and saying what I was thinking.

NVS,

I got a chance to flesh out a basic diagram, but can't really understand the power to lights portion of what you mean.



Care to elaborate from here?

Here you go...

[Figuarus]

NVS, Thanks! that clarifies it so much!

I'm gonna get the parts tonight, and i'll report back in the next week or so on how it all went down.

one more thing, are the two wires you list as factory actually green and yellow?

I know they are on the tail light wiring harness and intermediate wiring harness but I don't think so under the dash.

[Figuarus]

no worries, i'll just have to scrub the overspray from my wiring and find out what wires go where. Electrical is challenging enough, but when some mook just sprays paint everywhere, wiring in new items is done on hard mode.

Take a look!

If i'm reading the schematic right, it's designed to only illuminate the running lights side of the bulb.

I think...

This will work as long as the parking lights are off.. most early 70's and 80's GM vehicles with hazards from the factory didn't work if your foot was on the brake.. so similar pitfall except this is using parking lights.

Yup.. cheap easy flashers that work..

[Figuarus]

NVS, so then will this force me to have the lights off while I run the hazzards? What will happen if I run both at the same time?

The relay wired as I posted protects both circuits and nothing will happen if you have the parking light on or off with this hazard function on or off.. the only thing is, if you have the parking lights on and turn this hazard on you will not see the flashing; it will be steady on, since the parking lights are on.

I have not done it yet but worked out the scheme and bought the relay.
The idea is to use a 4 pole double throw relay. Power to the primary set of output poles comes thru the turnsignal switch. Power for the secondary (hazard circuit) is provided thru another flasher which has it's own 12V source. A simple switch throws the relay to actuate the hazard flashing. You have to split the 4 output wires for each signal light where they come out of the signal switch loom at the steering column to have the separated circuitry.

The diagram shows the relay in it's "resting" position.
The 4 signal wires out of the TS switch go to #'s 1,2,3,4 and out from #'s9,10,11,12 to each corner bulb. The hazard flasher is wired to #'s 5,6,7,8 which are jumpered together. A switch puts power to #13 to energize the relay. #14 is grounded. You could run a wire from the 5678 gang to an indicator light I guess.
Should work....I think....I'm pretty sure.

[jtrichard]

Mackie where did you find that relay and do you have part#? I was looking for one to do just what you are thinking

[Mackie]

I got this one but it will likely prove too light at only 5A rating. That and 3A is all they offer in 12V.

I had to move my `63 to my new home recently along with a bunch of belongings. Over 600 miles on interstates pulling a loaded trailer I wanted some kind of hazard flashing function. I rigged up a quick solution by jumping between the L&R rear signal wires at the plug in the firewall under the dash thru a toggle switch. Flip the switch and turn on the left signal gave me 3-way flasher (L front and both rear). Better than nothing but I had to keep careful track so I wouldn't be hazardin when I just wanted to be signalin.

[jtrichard]

Your 3way got me thinking you could use this http://www.ebay.com/itm/221970211687...84.m1436.l2649 and wire the right front and rear to it with a toggle and flasher and turn it on and left turn OR use two of them and have FULL front and rear hazards with a 30AMP relay

[Mackie]

Switches switchin switches ! Aint relays cool?

[Mackie]

How about 2 of these rated 10A. One for front lights and one for rears?

I think your 5A contacts should be okay as long you aren't driving more than one bulb per corner. A standard 1157 bulb runs about 28 watts or ~2 amps at 14 volts on the brighter filament used for the brake and turn signal.

It's a clever idea.

The more I think about it, I like the idea jtrichard talked about with using 2 separate DPDT relays (avail. in higher amps) to divide front/rear. The single 4PDT I could only find in 12V 5A. In the hazard mode all 4 bulbs would fire at once loading pretty heavy. Going retro-fit LED bulbs might fix that.
Plus, using 2) DPDT is a better option as it leaves you with one end functioning if one of the relays craps out. The relay link I last posted has sockets available too, solder lugs or screw terminal.

[jtrichard]

found this one think i will try it ....hey for 8 bucks cant hurt http://www.ebay.com/itm/1-set-LY4NJ-...kAAMXQgPhRkf79 10 amps should be great

[Mackie]

Cool, post your results.

Any progress on this?
