Hi all,
TL,DR; I believe I need a new flasher relay - can anyone recommend a decent replacement brand? I've previously had issues with multiple hazard light switch replacements before I found a decent one. I don't have the towing electrics point connected anymore as it was causing huge electrical issues when I bought the vehicle so that part of the loom was bypassed - I don't have a trailer or need one which may impact the type of relay I can go for.
Current relay is Land Rover OEM.
More context if anyone wants to help diagnose: stupidly left my dome light on overnight and needed to charge the battery. Fully charged and refit, although I did touch the positive to the seatbox by accident for about 1 second when my ratchet slipped which sparked.
Went to go tow a neighbour from about 1 mile away back to their house earlier this morning. Side note, first time starting since battery put back in and started up immediately, however randomly cut out totally dead (not stalled) when I went to pull away. 2nd time absolutely no issues. Also seems like she was slightly underpowered when pulling off but I think that's likely from sitting for 3 days in the cold.
Indicators worked fine on the way there. When towing back, indicators and hazards were making a buzzing noise if I tried to use but only noticed this when stopped at a junction. Got home, took the fuse panel off and yes, buzzing noise is coming from flasher relay behind the metal fuse mount.
When ignition off, hazards make relay buzz. When engine on but idling, indicators and hazard switch make it buzz, but less so. Battery at 12.5V when ignition off, off, 14.3V when on. When in neutral but small amount of power through accelerator, both indicator directions and hazard switch all work perfectly.
I think it could be something loose and vibrations making it "seat" properly when under power, as the voltage doesn't change between idling vs. a bit of power.
I've pulled the relay and can't see any corroded pins. Wires into back of plug are all solid. The plastic clips that seat the unit weren't on properly so it was "floating" next to the mount. Weirdly couldn't get any proper resistance reading from it with multimetre (checked multiple vids to make sure I wasn't doing it wrong).
Reinstalled it all and it seemed to be working absolutely fine with key turned to first position, and again worked fine when engine on. Rechecked, so engine off. Turned engine off went back to buzzing on first key position. Continued when engine on. Again a blip of power through the accelerator sorted it out again and was then working fine. Next time engine off, first position, engine on again, it worked absolutely fine. 3rd time it had issues again, 5th time it worked perfectly again. Baffling.
So, if any of that helps anyone diagnose, I'm all ears. Occam's razor says relay is failing, hence the question - what would you guys recommend for a good replacement?
Cheers!
