Want to remove flasher unit - help needed
« on: January 04, 2012, 12:44:24 PM »
Hi

I have my LED "Fairy Lights" up all year in my back garden as garden lighting - I bought a new set of 250 white LED sting light from Aldi which has a green flasher unit wired inline near the transformer end.

Some how this has filled up with water and last night stopped working...I just opened it and all the components are corroded, so I would like to remove the unit from the circuit  as I'm not a great fan of flashing lights at best of times.

My problem is that there are 2 wires coming into the flasher unit  from the transformer and 3 going out  to the string, so  how do I join these to get power directly from the transformer to the string with out the flasher unit.

Any help will be greatly appreciated

Cheers

Ess, how you bypass the controller will depend on what type of light set it it.

Are these lights 240V direct connection or do they have a transformer?

Doh - missed the mention of transformer!

You can bypass the multifunction controllers, but you will need to use 4 diodes (or a diode bridge) to perform the rectification that was occurring in the MFC.

David - My MFC does not have the common wire marked in any way but the one closest to the input wires is the center wire in the 3 strand. Would that be it?

Thanks again for your help

Cheers

Sorry . - Another question.

I'm on Bribie Island and we only have a Dick Smith here . Just checked and they have this

http://dicksmith.com.au/product/Z3250/rectifier-diode

Is that the same thing and will that work?

Dick smith don't seem to sell diode bridges any more.  As X said, Jaycar will have them.

You will need 4 and make the rectifier yourself if you get the single diode from dick smith the package in the wiki is the complete unit of 4 and I think would be better for you  as XDU said from Caboolture Jaycar
