Why did u bypass it by add the switch. I guess what I am want to know what is not working when you put it back to the way it supposed be. Won't start,will start,start but when u pull pto it dies,when running awhile it does,guess I am looking for little bit more info. There is some simple test you can do to determine what might be wrong with using a test light. Give us little bit more info and we will go from there. Thanks
