Flasher relay no flashing???
« on: July 09, 2016, 08:16:58 AM »
Ok, I'll try and make this short and sweet. '75 850t flasher relay doesn't want to flash. Can't get signal lights on period. Hooked up all 4 turn signals I have and none of them came on (unless all 4 bulbs happen to be bad, I didn't take the time to take 4 lenses off). I hear the flasher relay itself click/actuate when I turn the key so I'm assuming I have that wired correctly. I have continuity on both turn signal wires front to back, but can't get a volt reading on them when I have power running. Not sure if I'm supposed to or not, but I figure it's worth mentioning. I know hardly anything about relays but 2 of the 3 terminals have continuity, the one on I believe the left doesn't want to read.

The only thing I can think is that its the turn signal switch itself or I do in fact have 4 ruined bulbs. Would the rear flasher unit affect any of this? Only just now thought of that >.<

It could be a bad relay. They're pretty cheap and readily available at parts stores. My G5 also had 2 relays factory, but you can remove the jumper and use just one. I think the modern relays handle higher amps.

I asked a similar question a few years ago and the thread shows part numbers and such. I'll link it to this if I find it.

Hope that helps

Just because the flasher clicks does not mean it is doing anything useful.  Contacts can burn out and it will still click.

Disconnect the flasher and put a direct wire connection in place of it.  Then the turn signals for each side should come on steady when you push on the switch.

What will I want to directly wire it to?

Charlie means unplug the relay and plug a short piece of wire in it's place to send direct power to the direction switch
then when you operate the switch either side will come on steady to prove the bulbs and wiring
Just be a bit careful if it's a 3 terminal flasher, we don't want to connect hot to chassis.

Yep, the flasher should be direct to the fusebox and then directly to the battery.  They should work without a key.  It really is not a relay, just a switch.

And, yes, I meant for you to disconnect the flasher unit and connect the two wires to each other with a jumper.

I understand now, I just don't want to blow anything up lol
