I have a little experience with wiring after having to hot-wire my aftermarket radio in my car when changing it out, however I do not know how to fix this issue. The wires in the plug were loose and the lights were not turning on because of this, so i cut it off and figured it'd be as simple as connecting to two wires to another plug / power source, however that has not worked. I disassembled the switch box to take a look at that, however I don't quite know how to go about repairing this. I could get new lights, but these ones are already strung up how I would like and it was a hassle to get it to go evenly around the room, so I would prefer to be able to just replace the end of this one so I can still use them. Photos attached, any help is greatly appreciated! Thank you!

 

Can you describe the power source? A picture of the plug would help too.
Good luck......

It was just a normal plug, the wires got loose because it was this clear jelly resin thing instead of a proper shell. It wasn't any kind of fancy adapter or anything because the switch itself is the box before it plugs into the wall.

 

This is the plug that was on it (but US instead) and the left is the switch box that is disassembled in the previous pics.

 

That circuit has two thyristor outputs, that pull each set down to ground, it has a microprocessor on a circuit board in the middle.
You can check the mains supply at the input if you have a multimeter.

I have a multimeter at work I can borrow and use -- could I also just rewire it to a new switch? I really don't need all 8 options anyway... just simple on/off is good enough for me. If I did this, how would I take the 3 wires and change it to 2 for the switch/plug?

 

The lights are run on DC and are pulsed for different effects, if you want to by pass this, you can wire the lights on permanently by joining them together.

You can link A and B together and connect them to Live terminal, and C to Neutral, .View attachment 279455

With all due respect, I don’t think we know enough to say that.

How would I be able to know if I can do this? Considering the plug is part of the problem is there a different way to test it?

 

On your pcb the mains is rectified to DC by the four diodes, the DC is marked P and N,( positive and negative) the lights are pulled down to Negative by the thyristors and the common side for the lights is Positive supply.

You can measure the supply at P & N it will be Around 120V, and as a test you can temporarily link terminals 1 to 3 or 2 to 3 to see if the lights come on .

 

okay, i have this switch -- how do i know which colour goes to which terminal?

if i can figure out this then i can do each terminal one at a time and connect the wires, completely removing the motherboard and just using the switch -- right?

 

I think that switch is a one way type with an earth, put your meter on ohms or diode test and measure between the White and Black, and flick the switch, then try again using the Green with Black and White.

 

white + black = jumps up and then down to 0
white + green = 2.0 ~ 3.0
green + black = jumps up and back down

 

124 v measure between any with the v~ setting
