Engine Ground and Blown Fuses

[ICrushedAPrius]

Hey guys,
Got a big problem here. I keep blowing 30A fuses in my fuse panel. 3 different fuses that do not effect the performance of the truck as far as I can tell. I have heard that if the engine "ground straps" have corroded or rusted, the engine not being grounded will blow fuses. Is this true, and how do I check for engine ground? Also, if that is the problem, do I have to use the grounding straps or can I just replace them with a very large gauge wire?
Thanks

strart off checking the ones that run from the battery to the chassi and from the battery to the motor block, if there rusted or corroted change them or clean them. i changed all mine with a 0 gauge wire all my grounds from the battery to the chassi and the ones to the motor block. i also change the one from the alternater to the battery to 0 gauge wire. evlerything works really good with no problems, hope this helps
