flasher unit/relay

[Grenuj]

tnx @Crelesy .
5 amp fuse, is it correct?

 

[André4Renaults]

A 5 amp fuse is correct, as the 2 bulbs are 21 watts each, making 42 watts in total, which is under 4 amps. As to why the fuse keeps blowing, I wonder if, by taking the flasher apart, you have bent a piece of it and its shorting out onto the frame of the flasher, thus blowing the fuse. DON'T be tempted to but a higher rated fuse in, as you might cause a fire!

I'd buy a new flasher unit if I were you-you're going to have to in the end!

I could probably find that part in Bosnia, Banja Luka.

If you have someone traveling from Bosnia to your place I could send it to you?

 

[André4Renaults]

I don't think there's an export ban on flasher units at the moment.... I'm happy to post one from the U.K., if that helps.

 

[Grenuj]

I'll try to find it in all stores today...
You show empathy toward some stranger..
@Strmoslava , @Andrew4Renaults , thank you brothers!

 

[Grenuj]

no one store has flasher with 3 pin.
I'll try to fix the old one...he worked before opening..
perhaps the relay is touching the case..

 

[Grenuj]

continuity check, I have result in a loud beep..two pin (L & X) are electrically connected.
is it correct??

 

[Crelesy]

That's correct. But there must be some risistance for it is a spool.
X is +, L is load(to the indicator switch and then to the actual lightbulbs and P is for the dashlight. X could allso come from the emergency lights switch. ( Still a +)
I don't know your years scematics...

[André4Renaults]

I suspect your fuse blowing problem is because the bimetallic strip is touching the metal casing of the unit, thus earthing the 12 volts from terminal "X" & therefore blowing the fuse. You might be able to rearrange this, by g-e-n-t-l-y bending the strip a little away from the case, and using your meter to check there's no longer a dead short.

 

[Grenuj]

no short circuit, i checked it (tested with a multimeter, case and L or X between pair of probes - not connected).. thanks anyway @Andrew4Renaults ..
I must check contact resistance to diagnose relay problems. Anywhere from 50-120 ohms is OK?
Probably time for a new relay.. but not available in Montenegro.

Replacing old flasher unit with modern relay?
this one is available in stores, 3.5EUR.

 

[Crelesy]

I found this :

Is a simple fix and with 2 diodes you even have dash signal light working.

This one ought to work properly. Connect the 49 terminal to the fused feed, the 31 to a good earth & the 49a to the indicator switch and it ought to work perfectly!

This flasher unit is mainly for VW cars with a different flasher / switch layout. You won't have indicator light by using this flasher unit, plus, you have to modify the plug. The "L - P - X" type is extremely popular and used on almost all cars, I wonder why you can't find it in your country.

 

[Grenuj]

I wonder why you can't find it in your country.

The quantity of a good supplied by producers equals the quantity demanded by consumers.

I was chatting with a guy running an automotive electric parts shop, and he told me "...I wonder what to do with these thermal flasher units...I have around three thousands of them"!

 

[AdamWilkes]

If bimetallic strip is touching the case and shorting out when in use, testing it when disconnected may not show the short.

 

[Grenuj]

what to do with these thermal flasher units

to send one to Montenegro...

 

[Grenuj]

The flasher started working after a few kilometers of driving...
