    makes sure you check all your grond cables and clean all the battery posts. #1 cause of electrical problems, besides calcium

    Is it possible that you have a bad starter? Or that the wires were not correctly connected, as it sounds like a dead short to blow that big of a fuse that quickly.

    Check or change out your ignition and or starter relays. I have a 2006 387 with a C15 and I had the same problems.

    I took it to the TA after a road call to get it started and the mechanic swapped the relays and now I have no more problems. The is also 1 in the glove box on my truck.
