Hi, I'm Mike G nd I'll be assisting you. First thing, you should only have one wire under a screw. If more than one, connect the wired together with a short pigtail wire and connect it to the screw. Multiple wires under a screw will fail the connection and cause arcing which will make repairs more expensive. Yes, you may install a dimmer in place of the switch.
Connect all 3 wires together with a short pigtail wire in a wirenut. Connect the other end of the pigtail to the screw. You will continue to have power and it will not fail as having 3 wires under a screw.
OK, one of the 3 wires is to the light and needs to be on a switch with an additional pigtail to the same switch from the other wires.
Very good, let me know how it went.
#14/2 NM. Strip it and you'll have a single #14 to use.
With all the wires not connected, is the light off? If yes, with your tester from ground to each wire find the hot wire. Now touch that wire to the others to see which wire goes to the light. When found put it on the switch and then connect the remaining wires together with the pigtails to the switches.
Not safely. You should have a tester available anytime you do anything electrical. You can pick up an inexpensive one at any home center for around$10.00. Get one, follow the instructions and let me know how it went.
OK, touch it to the other wires one at a time to see which one is the light. Put that wire and a pigtail on a switch. Now connect all pigtails and remaining wires together in a wirenut.
The wire to the light should only be on the switch, not in the wurenut. The pigtail to the switch is where it gets power, depending on the switch position.
Glad to help, you're welcome.
