I took a 12 volt lighted switch and a car turn signal light and connected them to a car battery. I fried the stranded wire that I used to create the circuit to test just the light!
My guess is you just shorted the switch across the battery. Wired correctly, the 18ga wire would handle the current for a turn signal lamp.
With any luck the blue smoke will settle in the basement before the wife notices.
I have not powered up the circuit I made. I will post some pictures once my camera gets recharged.
In order to test the circuit what power source should I use? I wanted to use the car battery I am going to power the radio with. I fried the 18 gauge stranded wire I intended to use so I wonder if a lower gauge single conductor wire would have been better.
If everything is wired correctly, the car battery is an OK power source. My circuit will easily run with 22 Ga. wire. For the switched contacts on the relay, 18Ga. will work for the turn lamp.
Happy to look at it before you apply power again.
