Original lights not taken out still work minus existing blown bulbs
I had no way of knowing the connection was different to other rooms as we couldn't even change bulb without ripping out the entire can (and ever bulb blows when we try to). While I do intended to replace the can with something more appropriate, I wanted to at least verify my LEDs work so (after I turned of the power) I cut the wires to the mr16 and tried joining the light wires with one of these to the connector that came with the bulbs
But when I turn on the power with the led light it doesn't work. when I retest in the other room it still works I verified power is going to the light wires (other lights on same circuit continue to work)
Extra information: 20amp circuit A dimmer circuit but the LEDs I got support dimmers (and verified in another room) I am also not very knowledgeable on US electrics as I'm not originally from here so I didn't really know that mr16 was a thing until was pulled out
Can anyone help me understand why these are not working or what I might be doing wrong, I fully acknowledge that the way I am currently testing is probably not best practice or 100% safe, but as I mentioned above I would like to verify LEDs work on circuit before I proceed. Any recommendations on how I should do it would also be welcomed. If I can avoid it I would rather not get an electrician out for this.
If I can provide any more information let me know.
