Crysler Voyaguer Current

Hello, I have a Crysler Voyaguer 2.5 diesel. Yesterday circulating normally, I caught a bump and stop the engine. It seems as if it did not reach current, since although there are interior lights, horn, radio, dashboard, etc., I don't even try to start.
Does anyone know if this car has a sorting in case? Does anyone know where it is?
I have made a bridge to the starter engine relay by putting dough and already tries to start, but of course, the problem persists because the fuel pump will not arrive current either.
That is, I need to know where the origin of the short is.
Thank you

Some vehicles have a safety terminal in case of shock may be that this is failing is usually the positive of the battery
