EP27 LED Turn Signal Flasher Relay

[L8ndeb]

Hello All,

Wiring up the turn signals, and I am using an aftermarket VW 66-67 turn signal switch with an EP27 LED Turn Signal Flasher Relay.
I have seen two different wiring diagrams, one which has 12v from the battery to the + on the relay, and one that has nothing to the + on the relay.
I tried the one with nothing on the + terminal and I got nothing. I hooked up the 12v from the battery to the +, and immediately the flasher started clicking.like the turn signals or flashers were on.
My question is, why would the relay start clicking immediately upon hooking up the battery?

TIA

BTW guys, I have the relay ground to the body if that makes a difference.

Looks like from my wiring diagrams power should come from the battery +, to the flasher relay (+ terminal), out of the flasher (- terminal our output) then to the common lead to the turn signal switch. The switch then connects that power to left or right lamps when 'switched'. Circuit is completed/grounded at the ground connection at the lamps.
The relay should "ground" through the TS switch.
Hope this helps?
Jeff

Seems it should be wired like diagram below.... Does your wiring follow diagram?

Well, after going back through my wiring, I found a mistake. I had the turn signal switch feed wired to L instead of L1. After changing that, and running the relay ground to the turn signal ground, then both to the frame ground, my signals lit up and flashed!
Thank you to you all for your help. Now onto the emergency flashers.

Hi Dale,

I have the same diagram. There are a couple purple things I hope you can clear up. What tells the relay to start working? In the hazard mode, the same question. It seems all the hazard switch does is distribute the power from “L”. What actually turns them on?
Finally, what does “pilot” mean?

TIA

Ok. One more question and I’ll leave you guys alone. Is L and L1 on the relay specifically for the signals and the hazard flashers, or does it matter which goes where?
I’m starting to think L1 draw’s it’s power from the ignition circuit and L from the battery.

TIA

Hi Dale and thanks for your reply. I will test when I get the dash installed as it has the hazard switch on it. The turn signals are working with the ignition, so that is wired correctly.
Again, thanks to you and the rest that responded.👍

Hello All,
Well as I posted, the turn signals work fine. The emergency flashers are causing me headaches.
As you will recall, I’m using a 5 pole led flasher. I’m also using a single pole, single throw switch for the emergency flashers. When I turn the switch on, the flashing unit starts clicking like normal, the switch night light starts flashing, but nothing to the corners.
I’m in need of guidance where the wire from the flasher for the emergency flashing goes? How is it hooked up to the corner (turn signal) lights?

TIA
