Turn Signal and Hazard Relays

Post by VelvetHammer » 19 Jan 2019 19:31

I've had this car apart for so long I can't remember which relay is turn signals and which is hazards.
Any ideas?

I think these are OEM but not sure.

The plugs are different. They can only go on the correct wire plugs.

Unless those rivets are loose.

Unfortunately my OEM harness (original to the car) doesn't have plugs, only spade connectors.

I've traced the schematics and know which set of green wires is for turn signals or hazards, but I don't know which relay is designed for each circuit.
Also which spade is each wire is suppose to be on? i.e. Is there a specific directional flow of electricity though the relay? Or can it flow either direction?

There is no functional difference in turn vs hazard flashing. Use either one. If the lights don't flash, reverse the connectors and try again.

Polarity won't matter. These are load dependent for their flash rate. Four way relies on 4 bulbs but the signal only on two. You may find that the signal flasher used on the 4 way might be too slow or the four way on the signal too fast. Just switch them. You have a 50% chance of plugging them in correctly

Ah, so the one marked 12V25WX2 could be for turn signals.
Thanks yet again

FWIW on my 71 wagon AND my 78 620 both use the flasher pin style on the left in the pic as the turn signal flasher.

Here's some info i missed on my initial research:

Per the site, it looks like there is polarity to the relay. My relays show X and L terminals as well.

From datsun1200.com [/url]http://datsun1200.com/modules/mediawiki ... rn_Signals[/url])

Terminals:
X: battery
L: lamp
Candlepower: 32 [32CP]
Cycles per Minute: 80 to 90 C/M

T/S Flasher
B5520-89993 UNIT-FLASHER 12V 50W $14 USD
NILES CF115 (23W x 2 + 3.4 w [49.4 watt])

"The original hazard relay for a 1977 Datsun 280z is a Niles HF566-12V, 32CP Max 6, 80C/M relay"

Hey Chad - On your 71 wagon, it would be interesting to confirm if you have a HF566 installed on your TS, and then count the cycles per minute. If these relays are load dependent as Mike suggests, your turn signals my not be flashing at the correct cycle rate. Not sure if it would be slower or faster, but would be in interesting experiment.

On the wagon I changed to a digital one years ago so I can't answer. It worked fine for years and then one day, poof, no worky. I had the digital already so I put it in and never looked back. I can check and see if it's got that 'L' plug or is just spade terminals as you say yours has. Haven't been under there for that part in years now. I can also check the truck if you like. Assuming someone didn't put in a new one at some point. I've only had the truck the last 8-10 years of it's life.

Memory is telling me that the L shaped plug was the signal flasher, and that other was the hazards....

I guess I’ll be finding out soon on the Greg Terry car myself! Keep us posted.

I use the same heavy duty ELECTRONIC flasher on both the turnsignal & hazard. Can't remember the brand, but bought at AutoZone, pretty sure part #EP12.
