    Hello!

    (disclaimer: I'm super new at all of this!)


    I had a problem with a MFC on some fairly lights I have so I ended up having to remove it entirely. After I took it out only half the lights now work and after reading the wiki about MFC removal here:
    http://auschristmaslighting.com/wiki/Bypassing_Multi_Function_Controllers#Total_MFC_Removal

    It seems that I have one of the 'post 2014' models were every second light is wired in reverse, I don't mind only having second one working (its better then none of them working) but I was wondering if the lights will last very long now? or will they burn out faster or something because double the current(?) is going through them compared to before. If so is there anyway to prevent this?

    Thanks in advance for any help!!

    Little bit more info edit:

    Its the type of lights in which the MFC was separate from the transformer, I dont know if its helpful but heres a picture of both:

    also since the MFC has been taken out the light do look a little brighter

    There will be points where the number of wires along the light set drops back to two. Count the number of 'ON' lights between any two of these points and multiply that by 10mA. If the current draw is equal to or less than this then you shouldn't have any problems.

    Ok mad! So there is 10 'ON' lights between each double cord so its drawing 100mA which is heaps less then the 193mA from the transformer so it should be sweet?
    Thanks for your help!

    Have you measured the current that it is drawing? It should be no more than 100mA regardless of the value written on the plugpack.
