Thanks guys, I will try running into conventional mode. I already did delete the engine. I tried to recover the engine and still nothing. Other engines run fine. How could I have shorted something out when the engine was on a bench and come into no contact with electricity. The only thing that did happen was the pin that holds the front truck on did fall into the body front and so did the washer . Could that have caused a short ?
Tank you very much for your help,jerry
