Slow indicator after rear wing replacement

Hi,

I replaced the OSR wing on my 1971 S2 2000 TC and the indicator initially stayed alight a definite lack of flash so I replaced the earth using the earthing point of the battery now they run very slow. However for some reason I earthed the live feed and they work OK but no repeater on dash. This affects only the Offside flasher the nearside appears to be fast......now very confused...the flasher relay is definitely the correct one and the hazards work OK but still no light on dash for Offside when hazards are on......help!

When you replaced the wing you would have disconnected and reconnected the bullet connectors. My guess is there's some corrosion on the positive feed there. I'd pull them apart again and give them a good going over with some WD-40 and a toothbrush if I were you. If you find things aren't improved I would check the condition of the wire leading up to the connector. It may have a partial beak giving you a high resistance.
 
Thanks for that I meant to say that I used a testing screwdriver from earth to live side. I replaced the bullet connectors and sprayed the whole lot with electrical cleaner....is it possible the relay is faulty even though it sort of works?
 
Hey Mark,

The relay (flasher unit) is the same one on for both sides so I doubt it's that. (Unless you are getting the fault on both sides and I missed that) They are reliant on having a decent current running through them to flip the bi-metal strip inside. If you have a poor ground or a bad connection, or a poorly switch on the circuit that can affect things on the flashing side of things. That's why when a bulb goes on one side your indicators go mad on that side.

Make sure the bulb hasn't got an internal short that's affecting it's draw (Sometimes old bulbs will do just that if they are disturbed) I had one go a while back just because I unscrewed the holder for some reason. In fact I would start by swapping the bulbs at the back and seeing if the problem goes to the other side. If it does I its almost certainly the bulb (cheap and easy fix)

If that isn't the culprit I'm afraid it'll most likely be a result of checking the system with an ohm meter. You want to see if you have a resistance in a wire that shouldn't be there. I test bulb will only indicate power, a meter can indicate a poor connection.

Hope that's of some help,

Steven
 
Thanks Steven,

As far as I can tell \I have good current but will replace bulbs also wonder if the actual flasher unit can wear internally thus making poor contact so will also replace that.

It was a fluke when I used a testing screwdriver earth to live feed they worked and when I thought about it, wondered if it was because it slightly increased the current to the lamp, therefore as the repeater was not working I thought replace that bulb and see....and it worked... seems that if there is slightly less current there is insufficient power to make flashers flash! :shock:
 
Makes sense. You need enough current to heat up a bi-metal strip inside the flasher for it to work.
