Hi all,
I have a 1989 90 with a bit of an indicator problem. It still has all of the old style electronics, with old type fuses.

Anyway my indicators are flashing too quickly Left/Right and on Hazards all at same frequency.
So far I have:
Replaced relay with OEM
Tested grounding on bulbs (grounding to chassis fine).
Fuses seem fine.

Possible things I can think of:
I've inherited an unusual towbar electronics configuration, it seems to have two wired outlets.
Hazard warning light isn't working but indicators warning light is.
Full beam flasher circuit isn't working.

Please help I bloody hate electronics and I'm running in circles. What is relevent and what should I check?

Cheers in advance and hope you're having a good Friday.

First thing I did with my son's Ninety was to clean all the fuse holder contacts and fit the correct rated fuses.
Can you disconnect the dodgy towbar electrics so you can discount that.

All of it is tied in to the Hazzard switch and they like to die.

I mean I've not properly engaged my brain on your post, but if I had to place a quick bet...

Just to confirm, the hazard switch can be faulty without breaking the circuit? By which I mean they're all flashing (too quickly) when I put hazard switch on.

As @julianf above, faulty hazard switch often causes issues. Cheap enough to swap out.

Hazzard switch is full of magic. Magic can sometimes leak out.

In my experience, sometimes this happens before you even buy the switch.

I've replaced the hazard switch from an old britpart to a new posh one but no luck. Same as before.

When I can get round to it, I will try and sort out the wiring at the towbar but it might not be for a few weeks!
