Shorted the wire in the oil heater - how to repair?
Hello! My heater was short-circuited, namely, a wire that fits the thermostat from the trip relay (I don’t know what it’s called, I apologize). Oil heater. I noticed that the wire "earth", suitable for the ten, was a little flooded with oil and some kind of darkened places. Please help if you can. Attached a photo, but because you can send only one photo, then I inserted a photo of the thermostat, relay, earth wire, shorted wire into it.
