'79 GS 425 LED Turn Signal Help

[seamax]

First of all I wanted to saw 'Hi'. This is my '79 GS425 I'm building.



The issue I currently have is that I replaced all four turn signals, brake and running lights with LED's. With the stock flasher relay, all four turn signals would be lit when the turn signal switch is engaged left or right. Brake and running lights work correctly.

So I bought one of these cheap 'suitable for LED' flasher relays of EBAY.

Now all four turn signals blink when turn signal switch is engage left or right.

Here is the wiring diagram.



Can someone give me some insight on why this is happening and what I can do to fix this.

This board had been a great resource in helping my build. Thanks.

I think I found a solution from another thread here but need help with the wire diagram.

If you have a single [turn signal indicator] bulb in the instrument panel, it is fed by two hot wires from the turn signals. The indicator bulb acts as a current limiter and uses the turn signals on the other side as a ground wire. When the left turn signals are on, the indicator will also light, but won't pass enough current to light the right-side signals, so it uses them as a ground. Same thing for the other side.

If you want to use a single LED for your indicator, there is no problem, as long as you use a couple other LEDs to feed it.

Here is a diagram I did for somebody doing the same thing some time ago. It only shows the lights, not the wires that come from the controls, etc., but it shows the original setup with a standard bulb, then how to wire in two LEDs that will allow the use of a single LED in the instrument panel.



Option 1: I can pull the signal indicator bulb and my LED turn signals would work. I understand that.

Option 2: I do not under stand how to add additional LED's as shown the in the bottom wiring picture. Sorry I'm not very electrically savvy. Can someone explain to me how and where the additionla LED's need to added?

Hi,

The diagram shows 2 diodes and one LED. The diodes keep the current from "leaking" across the indicator bulb.


Thank you for your indulgence,

OK. That makes sense now. Will have to do some soldering. Thank you.
