Indicater stem light

[tedlogan]

Any ideas as to why my indicater stem light flashes once then stops? This is one of the many jobs I have to do as it failed the mot! Indicater still works just the stem light flashes once then stops! Any ideas!

Are all your indicator bulbs working?
Could be a faulty flasher unit

[tedlogan]

Yes all four bulbs work fine and continue to flash after the green stem light cuts out!

Definitely the flasher can...........

[tedlogan]

Flasher can, is that a relay?

[bmcecosse]

No - it's a can with the flasher gubbins inside......

[tedlogan]

Theres more to an indicater than meets the eye! What is a flasher can? Where does it go? Is it easy to replace?

[bmcecosse]

Usually a silvery can with 3 terminals on the base - screwed to the engine side of the bulkhead, near the control box. Modern units are of course plastic devices, usually black......

My flasher unit/can is on the inner drivers side wing.Ihave a problem with mine at the moment,had two spare new ones(not Lucas) which don't work properly but have a lucas one in the post which I hope will cure it

[mike.perry]

Is the flasher unit wired up correctly?
Is it the correct rating 42 +5 W?

[jedgarrett]

New flasher unit fitted and indicaters work a treat,however for some reason the light on the indicator stalk is on permanantly when the ignition is on,anybody got any ideas?

[bmcecosse]

Is it a 3 terminal flasher unit - have you wired it correctly? I suspect not! Swap the wires around....

[aupickup]

i think plain light green goes to the center terminal

[jedgarrett]

Certain it's wired up properly,can't remember what happend when swaping terminals but it wasn't correct.Put the old one back on which worked perfectly for a minute or so then packed in again.I've a fealing the replacement flasher unit is also duff!!

[bmcecosse]

Swap the connections around and try it - don't think it can do any harm.

[mike.perry]

Green - Fuse to Term B (or X)
Green/Brown - Ind Switch to Term L
Light Green - Warning Light to Term P
12V 21Wx2+5W

[bmcecosse]

Indeed - but just a chance the terminals inside the flasher have been connected wrongly.

[jedgarrett]

Just fitted yet another flasher can,stalk light stays off however front right indicater won't come on!

1.Bulb works fine when swapped to other side
2.Continuity seems ok from bulb holder to power feed
3.Continuity through green/white wire (control box to indicator green feed) seems fine
4.Swapped the feed to use left indicator at controll box and this works

So after all the flasher canns I'm presuming that the control box is at fault?
