Burned out flasher unit

Post by Jamiexr2 »

Hello
I was replacing my indicator holder as it was corroded and flasher not working.
When I did I noticed smoke coming from the flasher unit and now nothing works.
Have I con ected negative to positive and fried it?
I now k ow what the negative wire is.
New unit is ordered with negative earth.
Any advice would be great.
Thanks
Jamie

Possibly shorted it if you were playing with the fitting with the indicators on.

Or it was about to fail anyway.

You are not putting LED bulbs in the indicators are you?

LEDs don't have sufficient load to work the old style flasher units which rely on sufficient current to heat up a bi metallic strip until it bends and opens the switch. Eventually the moving bit either breaks or sticks shut. Not enough load and they don't flash, which is what can happen when a single bulb blows. The other end of the car lights but doesn't flash or flashes very slowly.

They can be made to work by using an extra resistor to give the load or by getting a ore modern electronic flasher unit that isn't load sensitive.

A good bulb holder, with a good earth, normal bulb, a new flasher unit and it should be fine.

Sean.
