Engine doesn’t start!

Hello guys, I’ve had a big problem this morning. I wanted to go to work with the OMI this morning (or else drive the train). So in the car, keys on preheaters, coil lamp goes off, keys turn around all the way and……nothing! No clacking, no turning of the engine or the starter. Oh so, I thought: Automatic so he won’t stand on “P”. But thought. He was on “P”. Choosing levers several times up and down. Again on “P”. Again keys turned around and…….again nothing. Battery has full juice, yet the engine doesn’t give me any noise. Who can help me? lg Hajo
