Thank god someone does, I have read alot of Coppertops old posts and they have intrigued me. Has anyone actually integrated this circuit into their wiring harness? I am working on mine now and keep finding all these neat ideas on this website....

What is it, What does it do?

Its a circuit that blinks the side marker lamp on our cars like the newer cars of today. The Turn signal lamp flashes and when it goes off the side marker lamp flashes alternately. (In simple form) Do a search for "winker" or "blinker" and you'll find more technical data on the circuit.

Scott, Sorry it took so long to get back to you.
I finally found it. Then my scanner was on the fritz, then I got sent to Helpaso for a broken aircraft then....
Anyway glad you got it.
The only thing my sheets dont have is the parts list. Does anyone have that?
would you send it to me please.
Thanks

Philip,

Do you mean the part numbers for the transistors and the resistor values?

Here they are:
Diodes D1 & D2= 1N4004
Resistors R1=2200 ohms
R2 & R3 = 10000 ohms
Transistors Q1, Q2, Q3 = 2N4401

Hope this is what you want. Have you(or anyone else) figured out where to put this circuit physically? I read an old post about using a micro- relay cover. Are you planning on having a circuit board made for this or just soldering the leads of the components together? The latter seems like a bad idea, but I dont know where to get circuit boards made..... Any thoughts?

This can also be done with a single relay. But it would work a little differently. When the lights are off the marker would flash with the signal. When the lights are on, the marker flashes opposite to the signal. If anyone wants to know I can try to describe how.

Please describe the relay idea. I think I know but want to hear your idea.

Philip
As far as a circuit board, Radio Shed has blank perforated boards, snap them off as big as you need it and lay the leads under it to connect. Insulate where they cross. Tuck that up under the dash or stuff it into a little box.

The relay should connect something like this;
Connect the common contact to the light bulb gound wire.
Connect the NC contact to ground.
Connect the NO contact to power.
Connect the coil to the signal light bulb wire and to ground.

If I'm not mistaken, all these cars have plastic side markers with ground and power wires going to the socket so it should work for them.
