Indicator Flasher relays

Recommended Posts

When I put the dash back in the car it looks like the flasher relays took a bit of a hit and the case fell off the one and the indicators now operate very slowly!

So I thought I'd just replace them -- but can't work out what I need! There are two units - so match up with the wiring diagram I have, but not sure if I just need two GFU2124 or one and a GFU2204

Any one any ideas!

On the later cars there are two flasher units - on my GT6 it's one behind the dash and one near the battery - because one is for indicators (the dash one) and the other is for hazards. They are different units because they carry different currents (two or four bulbs being driven).

Mark, I strongly recommend buying electronic flasher units. They just need an earth wire in addition to the existing 2 wires per unit.

They give a nice constant flash rate, and far more reliable than the new "original type" units.

Had one from Halfords, and a couple off ebay, plus some from Beales (garage supplies) all work reliably and have done so for some years.

Thanks Clive. I’ve ordered a couple from amazon - each will do from 0.1-150w. Including led. No obvious mounting bracket but I’ll sort something out. £9 the two. 

I think they may have a push-in tab? some relays do, others don't. Then again most of the spitfires I have had the pleasure to work on have had the flasher relays dangling mid-air. But best to have them attached.

I used a couple of those units (from ebay) fitted to the daughters mini. Had that car 4 years, no issues.

Sadly my GT6 now has that condition. The original shape units are no longer available and the round ones that the specialists all sell for it won't even get close to fitting in the clip behind the dash.

I've got my indicators working again now :)

But they don't make an audible tick when flashing - the MOT test doesn't seem to suggest that is checked (mine doesn't have an MOT but must still pass one as you all know!) - but I can't remember if you need one or if the visual is ok!

Can’t be on the incoming supply as that is permanent. It switches on the other side and relies on the circuit being made first by the indicator switch and then the bulb going to earth.  
Would work on the out going side though. As long as the current draw is low.
