Constantly tripping circuit breaker

I have a Maytag MGS5770ADB stove that will trip the circuit breaker if it plugged in. I have isolated to the spark ignitor circuit by removing the black wire from the terminal block. With that removed I can now turn on the circuit breaker without it tripping. After replacing the spark module the circuit breaker still trips. I assume this means there is a short with the switches. Any other suggestions?
