What Would Happen if a Diode Received Power on Both Inputs at the Same Time
Question:
I read your answer to this Question but cannot figure out the answer in my application. In my application: I have Moose light in Alaska that have 4 Vision X Canon Lights 28 amps total. They controlled by upfitter switches Ford 250, one switch for on/off and another switch that allows a relay from High Beams to turn them on and off. My worry is that if I have them oninch by switch and then turn on the high beams the diode will have a feed ininch from both relays into the Moose lights. Your diode look perfect for my application but will 2 sources of power into the diode damage the lights both on a 40 amp relay circuit.

If the two power sources are going to be on the same, input side of the diode then the current would flow through it without an issue. If you put power on both sides of the input side of the # RM-790 the current on the output side of the diode would not be affected. Basically the higher current on the two inputs would be the circuit that would make it to the output side. If the current was put on the output side of the diode it would not travel through the diode.
Diodes like the part # RM-790 only allow current to flow in one direction. Usually a diode is a small cylindrical shaped component (not in this case) which has two leads on it, the anode and the cathode. When the anode side of the diode is facing towards the positive power source of the voltage it will allow the circuit to be completed and is considered "forward biased." If the cathode side of the diode is facing towards the positive side of the voltage then the diode will not allow the circuit to be completed.
