so long as you fit led timer relay (tin can) for both indicators and hazard lights and all earths are good (need to be really clean then smear with petroleum jelly to prevent future corrosion) should have no problems. running resistors with led is to increase load so get around using correct relay. as i'm lazy its easier to fit the relay!

Sounds like an awful lot of hassle to me... What problem were you trying to solve in the first place?

[PoolGuy]

The Classic Car led flasher comes with a dedicated wire for the indicator warning light, so you shouldn't get the issues that you have, which iirc is only a problem with a two pin flasher unit? https://www.classicc...k-x-l-p-2-3-pin

I swapped out the old 2 pin for The CC led 2 pin with the additional Earth wire. my mini is a 1972 and the flasher is beside the washer bottle . or have I got it all wrong

Did you remove the warning light as suggested by CC? 

[Ol timer]

not as yet. am hopefully doing that tonight . that will definitely show what the issue is

The wiring for the indicator warning light is likely to be causing this sympathy flash issue.  
It is likely to be wired between the left and right hand circuit and does not have a dedicated earth so earths on the opposing side. 
The current that goes over to the other side to find earth is not enough to light incandescent lamps but is enough to light LEDs and cause this "sympathy flash".


You can check that it is this wiring that is causing the issue, by removing the lamp from your indicator warning light. 

You should then find that the indicators work properly. 

To fix the issue permanently, you need to isolate this lamp from the opposing circuits and provide an earth for it. 

We build a harness kit as a simple cure.  You need the negative earth version which will be back in stock later this week

 

As I understand things you have a single repeater lamp on the Clockface ?

If that's right, then the flasher can needs to be a 3 pin type with the 3rd pin for the repeater lamp.

There is (or should be) a solid Earth connection on the back of the clock. If that's not there or has an issue, then usually the first thing that's noticed is the fuel and temp gauges read way over as well as the lamps playing up.

If you have 2 repeater lamps, then yes, a poor Earth on the back of the speedo will do as you are seeing, but I can't see why you'd need a special instrument harness for this, just sort the Earth on the speedo.

 

 

 

Spider,I am not saying fitting LED is bad but fitting resistors etc to make them work is perhaps not the best way to make them work.Electricity seems to be a mystic black art to some and there seems to be a lot of less than optimal kit for sale.Steve..

 

Sorry Steve, yes, I agree with that that is does seem mad to fit LEDs and then have to fit Resistors in order to make it all work. I think were I may have been going is 999 times out of 1000, Resistors while seeming a 'fix', aren't needed if all the right parts are used.

I have the old centre speedo with the single Indicator lamp. fuel and temp gauges seem to work fine.

The car had the twin flasher unit beside the wiper motor. it has 2 wires going to one terminal and one wire going to the other terminal

This same issue happens on many motorcycles when converting over to led indicators. It happens when there is a single, dash indicator bulb fitted, not a left and a right indicator. As the vendor explained above, the single warning lamp passes current to ground through the no lighting indicator bulbs. When standard incandescent, not sufficient to light up. When Led, plenty enough to light up wrong side at same time.
On motorcycles, the solution is a set of diodes on the warning lamp feed, called a "tweaker" setup. Cheap as chips, can be homemade from a few diodes from local electronics suppliers.
Cars/bikes with a separate left and right warning light do not need it.
I believe another solution is to fit a an Led as the warning lamp. Make sure it is the polarity insensitive type, which can pass current either direction.

seems. CC LEDS were spot on. I popped out the tell tale light from the dash and the indicators worked. so will leave it out for the time being. unfortunately the bulb holder bowl that is fixed to the speedo came away as well. so another fix to do on the weekend . thanks everyone for your help

[Aria Aradhea]

As an alternative to the indicator dash light, you could use the unused orange lights for indicators left and right and move the oil indicator light to the green one.

thanks for that idea. I did just that. actually didn't have any of the orange ones used. seems my mini don't have an oil warning light.It does however have an oil pressure gauge

That's right... for a 3-gauge oval binnacle, there will be no oil warning light. I believe the oil warning light will only be on the single-binnacle variant.

 

Hope you get the indicators working fine after this.

indicators all work fine now thanks to everyone's help. all external and internal lights are now LEDS.
