Hazards not working. Indicators work.

Hello
So I’ve had some bother with the indicators and hazards today. ie. I had none.
I’ve managed to get the indicators working after giving the relay a “tap”. But the hazards don’t work.
When the indicators didn’t work when I put them on with the stalk the fuel gauge would drop to nothing (this has now fixed itself with the “tap”.

Any idea what’s up with the hazards?

Thanks

Switch, it's always the switch!

Well nearly always!

Note that the indicators and hazard circuit are on separate supplies, so the dual issue makes me think connection at the relay perhaps - or the switch... somewhere AFTER the initial supply from the fuses anyway.

The tapping of various things suggests basically a bad connection, the feed for the fuel gauge also runs the indicators, so the gauge moving would indicate a loss of a low resistance electrical path, this higher resistance could be created by a connection at an earth or feed.

Connections - they can corrode up a bit and when the current draw is too great for the electrical path left through the corrosion, i.e. the indicators driving up demand over the high resistance it cannot deliver it kills the current - a bit like a combi boiler feeding a shower and a tap at the same time, the old ones used to practically kill the flow to a trickle at both.

Try cleaning up the earths and remove and reseat the fuses to "clean" them.

It may also be at the stalk but that wouldn't tend to explain the fuel gauge.

I'd start with checking the earths behind the dash, make sure they are clean and tight. After that test the switch or replace with a known good one.

Haven’t had a chance to have a look yet. Ill have a poke on Friday and report back

Was the switch on mine. There's more going on in there than you think.

There’s a good write-up somewhere ( on another forum, ahem ) about diagnosing the switch, have a Google for it. I’ll try looking for it too.
I ended up replacing stalk, hazard switch and relay before I sorted mine, and then the indicators started to play-up in the rain, this was traced to a leaky side repeater and corroded rear earth.

The hazard switches fail for giggles, even if they aren't used. I'd buy one now anyway, it probably will fail at some stage! The gauge behaving oddly does suggest a faulty earth in my experience.
