I have a 2007 mazda 5 that keeps blowing its ignition fuse. I was driving down the street when the van stopped dead. Found the fuse under the hood for the ignition was blown. Local parts store didn't have any 40 amp fuses so I put a 50 amp in to try and get it home. The second I turned the key it popes the 50 amp. Took the battery cable off and still sparks like it's drawing somewhere. Anyone have this trouble before.

 

sounds like a short somewhere, good luck, don't know if anyone has had your particualr problem, never heard of this one yet.
