Electrical Problem!!! PLEASE HELP ME!! SHORT CIRCUIT CAUSING REPEAT BLOWN FUSES

[i3litzace]

When I accelerate hard and or when i go over bumps my 30amp ignition fuse located in the engine bay keeps blowing. I took it to Nissan and they said it was the alternator but soon after the fuse blew again. Anyone out there had the same problem before??

I have a 95 nissan 240sx

anytime you consistently blow fuses, you have a short to ground somewhere. grab yourself a wiring diagram and trace it back as far as possible outside of that, i really dont know how else to figure that out. good luck
