Jenn-Air Oven not warming following power outtage
If you were able to visually confirm a burn at one of the terminals on an element, you probably have one of two issues: First would be a faulty connection at the element. Even if you're confident your repair is good, it's not a bad idea to double check for continuity between the repaired wire (check from the control board side of the wire) to the opposite terminal of the element. Make sure you turn off the breaker first. You should get a reading of 9-50 ohms. The reason for the wide range is that the wattage of the element determines the ohm reading and there are many, many different wattages. Anything below this range (less than 5 ohms ore more than 75) would indicate a poor connection or a failed element. If the element looks good, chances are it's working normally. If you want to double check the element, just check the resistance, terminal to terminal. Should be, again, 9-50 ohms.
If your wiring repair was successful (and I'm guessing it probably was), you probably have a faulty relay in the control board, or possibly a burn on the control board keeping L1 or L2 power from completing the circuit (elements use 240VAC) and you would need to replace the relay board or control board. Testing this board can be hazardous due to the conditions necessary to check for proper voltage from the board, so unless you're an electrician or have training in an electrical field, it's probably best to call an appliance repair company. Electricity doesn't always give you a second chance, so use your best judgement. Another factor pointing to a possible relay failure is the fact that you did find a burn at the element terminal. A burn indicates a poor connection which will spike the amperage through the entire circuit, burning the contacts in the relay in the process.
I hope this is helpful. If you do, indeed have a failed relay and must replace the control/relay board, be careful not to spend more money on the repair than the appliance is worth. A good rule of thumb with appliances manufactured after the mid 2000s is you don't want to spend more than half of what the appliance costs new if it's 5 years old or older. This applies to almost all major appliances. Best of luck!
