I wondered if someone could advise me on a problem I'm having fitting some 12v interior LEDs . I'm running them off a leisure battery and seemed to work fine but as soon as I introduce a switch into the circuit the wires get hot if the switch is off but fine if the switch is on? Thanks
Can you sketch, take a photo and upload a wiring diagram? Heat is due to current flow, so somthing is wrong with the wiring.
