R33 GTR Indicator Flashers vs Hazard Flasher Circuit

Hi SAU clan, I have been trying to sort this issue out to no avail. 
 

My R33 GTR- the hazard lights flash at normal speed, but as soon as I use the steering stalk to put left or right turn signal on, they flash fast. 
 

All conventional bulbs, and since the hazards flash normal I am tempted to say the bulbs are fine. None are blown.

Any idea how to tackle this?

Yes, but are all the bulbs actually working? There is a function built into INDICATOR flasher units to make them flash fast when a globe is out. That is not necessarily replicated in the hazard flasher.

And of course, if the bulbs are all fine and working, then the flasher unit is most likely to blame.

The Flasher unit, or flasher cam is a special relay which controls the timing of the indicator speed. Check your fuse box wiring to identify which relay is the flasher cam. Alternatively, you should be able to hear/feel which relay is the flasher cam/unit when you have the indicators on

Hi yes all 6 bulbs are working… where is the flasher “unit”? In the indicator stalk?

Flasher unit is in the dash, number 52 in this image next to the center console stack, it's next to the buzzer to remind you to remove your key and "circuit breaker" and is a black 3 pin relay. Not sure how you actually get to it though:

You just drop the lower dash cover. 4 screws.

I was under the impression it was to the right of the steering column, but ima check this weekend. I had ordered the r34 relay because the r33 one is discontinued. I assume it’ll work. If not I’ll just order a random eBay one. 
 

Thanks everyone, solid info.

Ok SAU friends, some updates. 

Searched high and low for a new relay, and found an R34 one. As expected, they have an identical exterior appearance and plug. 

Swapped the relay, and same issue- all the lights work, just flash fast. Hazard light circuit flashes normal speed.

Pretty confused by this. Like I said, all the bulbs are conventional, non LED.

I am tempted to buy one of those adjustable knob relays and just artificially slow it down, if that makes sense, also will try replacing some of the lights such as the rears to see if a new bulb helps. Unsure what else to try…

Time to start some low level fault finding work then. Measure the resistance of the circuits coming off the flasher can, looking for differences between LHS and RHS. Perhaps measure the resistance of individual globes. Maybe one of them has a weird internal short or (more likely) high resistance. Open circuit on a globe is what triggers the fast flash response, so high resistance (but still making some light) might do the same.

Perhaps wire up a completely external circuit using the original flasher can and some globes to see if it behaves itself under controlled circumstances.

etc etc.

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
