JerseyMini, At least you have power. I would start by checking all connections including the light bulbs, because the turn signal bulbs are subject to corrosion, remember you have to two contact points for each bulb. Leave the light on and determine which Fuse in the block powers that light. Save the switch for last because that's is a real pain to get to. Hope you get this issue solved.

I use LEDs on most of my Minis so I use the GROTE flasher relay from NAPA. Part #: GRO 44891 About $32.

I've been using parts store flashers for many years.

Look into heavy duty flasher units, which come in 2 or 3 terminal versions. Better to get one that is not load dependent, i.e. flashes at a constant rate no matter how many bulbs it is flashing - the kind you'd use if you wanted to connect a trailer.

Bluedragon describes the old style (and cheapest) which is actually a thermal type. (He has the action backwards - in its simplest form, it need current to activate the bi-metal and break the contacts.) Heavy duty electro-mechanical ones include a coil, circuit and contacts to regulate the flash speed no matter how many lamps it is serving.

Now there are electronic flashers with up to 5 pins... no idea what they do!

Old style mechanical turn signal flashers are thermally activated relays - the current passed into them heats up a high resistance metal strip, making it flex from the heat. This flexing makes contact with the circuit that lights up the turn signal bulbs.

But the completed circuit cools off that metal strip, so it flexes back to its original shape. That flexing makes a clicking sound, and breaks the lighting circuit, thus the turn signal flashes.

So if the turn signal is blinking too fast, it most likely means the flasher has too low a current capacity than the one specified for that application, and the excess current makes the metal strip flex more rapidly (easily) than intended by the manufacturer. Vice versa if it blinks too slowly or not at all.

I have to say that I'm not the authority on flashers and turn signals. I can say with certainty, they are problematic at times. I want to confirm that I tried a Car Quest Brand FSH 7059 (it's Black and squarish) into my 94 SPI. The relay fits but blinks rapidly, maybe 3 times the normal rate.

The car is an 88,the flasher currently in place is silver.Hmm,could that be the issue?

What year mini do you have? Late minis flasher relays are black and the early  flashers silver will not work

Is the flasher relay in the classic minis a basic unit that can be replaced from an auto parts store?

My hazards werent working,not sure if they ever did? But i wekt to turn my blinker on and they don't blink they just light up. Im assuming its the little silver flasher?

I went to the auto store last week to test one,and i guess i accidentally pushed in the hazard switch so they wouldn't work at ALL when i out the new flasher in and i was like oh great,this is even worse them drove home with no flashers period and felt like a jerk lol
