local Marker = createMarker ( 2048.68848, 1474.93945, 9.67188, "cylinder", 10.0, 155, 0, 0, 150, getRootElement( ) ) 
  
  
  
function elLoco() 
setPlayerWantedLevel  ( source, 3 ) 
end 
addEventHandler ("onMarkerHit", Marker, elLoco) 

what's wrong

[Baseplate]

The source of onMarkerHit event is the marker that was hit, you should use onMarkerHit parameters.

local Marker = createMarker ( 2048.68848, 1474.93945, 9.67188, "cylinder", 10.0, 155, 0, 0, 150) -- Isn't 10 as a size kinda too much? 
  
function elLoco(hElement) 
setPlayerWantedLevel(hElement, 3) 
end 
addEventHandler ("onMarkerHit", Marker, elLoco)
