Cat 301.8 No electrical power

Hello all I was using my Cat 301.8 today, tracked over a mound and it came down with a bit of a jolt, it instantly cut out and now I have no electrical power at all, nothing at the key. The battery is good. Is there a cut out somewhere on the machine that would cause it to do this? I have looked at the wires and the ignition barrel and can’t see anything broken or out of place. I desperately need the machine moved as it’s at a wedding venue that it’s in the middle of which is typical! Any help or guidance would be very much appreciated Thank you
