flashing :)

Someone humour me again for a moment......

I love wiring, it's great. Anyways, I could answer this question myself by going to Halfords and buying a flasher unit. But it's cold and wet, I don't want to go out and am hoping someone's bored enought to answer......

Hazard flashers don't flash, indicators work normally. When ignition on and one indicates either way ones hazard flashers work. At this stage they use the indicators flasher unit and according to my diagram they shouldn't, should use their own. Would it be logical to assume that they're only using this one as their own flasher unit has died? It does look old and tired. (different to indicator one so can't swap)

thanking you

Certainly my Tasmin used separate flasher units. Not sure, but I think the 390 only uses one. Your car? Who knows...
If it oly uses one, it could be that the hazard switch is kefurkled.

G'day Ian
Too true, does seem they're all subject to daily variations

Think I've decided the switch is OK, shoved paperclips across the wiring plug terminals in the way the switch links them and still nothing.

Ho humm, I'll venture out to Halfrauds t'moz and make the £3 investment in a new one

Then the question being, AA or RAC!? She still starts and no leaks atm!

Only one in mine (AFAIK) - S

Just had a similar problem but the other way round......hazards worked OK but neither indicator. After spending some time trying to find the fault heard a buzzing from one of the relays and it all started working, so I guess it was jammed.

Dave,
It says there are two flasher units for cars upto chassis 5903.
It also says that hazards share a fuse with the interior lights.
So if your int lights work good chance it's the flasher unit.

If it's a later chassis # re-post.

Jeff

Didn't spot they were on the same fuse, think int lights worked. Oh well, Halfords is open now, it's sunny so I'll venture out on the m'bike and we shall see......

She's quite a young 'un and chassis number is before that so should be that diagram. Though there are some variations!

The relays do like doing that, prob cos they're 20 yr old and don't like engine bays! I bought a pack of them from VWP and replaced them all.

[york33]

Well to it all

Hmmm, replacement hazard flasher unit does a manic flash, so fast the bulbs don't even illuminate! Seemingly the same type as before!

Washed the m'bike instead

Dave ,you know the saying, " if at first you don't succeed.......sod it ...go and have another beer!!!!"



took me 12 cans of Scrumpy Jack to 'see the light' with me 'Horn problem'

Sounds like you have a short on one of the lights. It's taking the flasher output to earth, draws tons of current, so the flasher cycles faster. The voltage drop caused by the short is the reason you don't actually see the lights.

Maybe I should write a book...

[jeff m]

I agree with Ian, the bulb filament is part of the circuit. (that's why when a bulb goes it flashes faster)
Better find that shorted bulb before your new flasher unit beats itself to death.

That MOT must be getting closer.
Jeff

[york33]

and a goo dsaying that is, hiccup

Now, ordinindarily I would agree with you all on the dead bul b bit.....but.....my indicators work OK (separate flasher), just not the hazards......

I killed one flasher unit already by dropping one of its terminals onto an earth and zapping it, slippery little burger!

MOT will be booked (after AA joined) as soon as I fix my 'kin hazards, mutter, mutter, zzzzzzzzzzzz...............

thanks 1 + all

[jeff m]

Dave,
Hmmmm yep.
I've sent you the wiring diags by e-mail.
Jeff

[york33]

thanks Jeff, that diag is good, has a key on it too

hmmm, I have a cunning plan, which involves another (different+relocated) flasher and a soldering iron! I'll try it tonight if it's not raining and I can see what I'm doing........

[york33]

Guess what!? She now flashes at all the appropriate times

I found a third flasher! Now removed two, replaced them with one for the hazard, put in my new flashy switch and hoorah!

thankyou all, I thinks I best have a pint

[york33]

Aaaaargh, put the kiss of death on her now, joined the AA and booked an MOT, eeeeeeek!
