Indicators flashing very fast!!!

[kristian]

My indicators on my cup are flashing very fast, yet all the bulbs are working.
It's both sides, could it be the flasher unit? Where is the flashed unit?
I was told it could be the hazard switch or a relay!!
I'm lost.... Where do I start??
Cheers kris

It could be a dodgy connection on your rear lights, give the wires a wiggle and see if they stop flashing so fast.

 

[welshname]

mine did this after i ploughed into a vectra.

only when i turned the hazards on or the indicator.

i think thats why they wrote the car off...

 

[kristian]

Il try a wiggle any other ideas? Could it be the flasher unit? And where is it?

 

[Sash]

got a lamp out? put your hazards on and walk round the car.

If it was the hazard switch, they wouldnt turn off or on.

 

[Clio_Al]

the ticking nosie gets very fast when a bulb is out is it that?

 

[kristian]

As stated, all bulbs work

Wrong wattage bulb in one of em, take em all out and check what they are

 

[kristian]

Are you Sure? It's both sides that's why I didn't think it would be a bulb? Cheers

 

[Arney]

wrong bulb wattage.. so not drawing enough current.. or bulb out..

 

[Setone]

does it happen all the time? or only when braking etc?

 

[kristian]

ALL bulbs WORK!!! Lol, il check wattage, just seems weird both sides are fast.

 

[James]

The current draw from the indicator circuit alters how the relay makes them flash, hence why when a bulb is out, they flash really fast. So if one or more of ur bulbs is a different wattage to others, yes they'll all work, but it'll be drawing a different amount of current to what it should be, so it'll flash quicker/slower/whatever

^^ All b****cks? could be lol

 

[Arney]

if it occurs when breaking then check the earth line on the brake light unit. look at the resistance and check the terminals for corrosion..

 

[kristian]

I'm fairly sure it's all the time, braking or not still fast.
Cheers, kris

 

[kristian]

Ok all bulbs are 21w so there correct, if I put my hazards on the flashing slows down to the correct speed, any ideas people???

 

[stephenn]

sounds like the begining of a dodgy earth in the rear lights, affects all lights and will get progressively worse
i checked everything and couldnt find it, took it too a local garage, the 1st thing he looks at was the problem :dapprove:

 

[Sash]

Take the connectors off the rear lights and clean them, they are more than likey a little corroded.

 

[kristian]

Ok cheers, but how does dirty connectors make the indicators flash fast?
Just interested... Thanks kris

 

[cander08]

it means bulb is about to go.lol

 

[kristian]

^^^^ yeah sure

 

[SimonR.]

The corrosion causes a bad earth connection, if they can't earth properly they break or blow a fuse.

Use a penknife to scratch the terminals to the metal and spray some wd40 on them.

 

[cander08]

am being deadly serious , my mates a mechanic . he slagged me silly when i asked him about the same thing.

 

[Setone]

i found that the earth termial on the light cluster plug had come loose. had the solder the crimp on in the end.

 

[kristian]

Can't seem to fix this!!! Still flashing fast, all bulbs fine, all connectors clean!!

 

[cander08]

strange one mate.

 

[Seb25]

I've always just had this problem when the bulbs on its way out...
