My indicators are flashing really fast both sides, but i dont have a bulb out. My hazard switch has never worked but my idicators were normal speed a week or so ago? 1990 mayfair by the way

Thanks

Well I will watch this thread with interest, as my indicators are the opposite, they flash a bit slowly, not slow enough to fail an MOT but slower then I would like, sorry I cant help just putting my one out there too incase it helps solve the OP's question :)

Mine are just irregular, they flash at a certain speed for a bit, then they speed up a bit then slow down again

Flasher unit will be on it's way out in all 3 cases. Change it for an indicator relay from the likes of Halfords etc, much more reliable and they flash at a steady rate. All you need to do is add an earth to the 3rd/spare terminal on the new relay.

I swapped both flasher units for relays and have reliable indicators.

Well my indicator flasher is brand new, will try a new one though. :)

Do you have a part number?

[billy_t15]

Anyone know?

Yes I agree get an elecctronic flasher unit, it's a quick and easy upgrade and they are much more reliable. This is what you need:

DO NOT buy any flasher units from Halfords though. They seem to be very poor quality and normally fail within a few minutes of being fitted.

What does the original relay look like I seem to have two?

Anyone?

Older Minis have an indicator flasher unit (it isn't really a relay) and a hazard flasher unit. The indicator flasher is usually round and under the dash so you can hear it click, hazards are square and will say "hazard" on them.

The indicator flasher relies on the resistance of the bulbs and wiring to control how fast the bimetallic strip inside it warms up & breaks the circuit to make it flash. If it's slow there's too much resistance, so check the earths and connections. Too fast means too little resistance, which might be a fused bulb or a short - give the wiring a once over in case it's the latter. Fitting an electronic flasher will correct the flashing but it won't fix the short if you have one.

Hazard flasher use an internal resistor so should always flash at the same rate, but there "default" position is with the flashers unlit which is why there are two units. Electronic flashers are used to do both jobs and are wired with an ignition switched relay (so you can't accidentally leave the indicators on), hence why calling Flasher units "relays" can be confusing.
