Tennis shoe steers you in the correct direction. Detecting the electrical problem in a vehicle where a fuse is blowing is no different than in a house. The problem comes in where the wiring in a vehicle looks like a spaghetti factory. To save time I suggest. Find a diagram of the electrical circuit for your ignition system, the problem is going to be there. Check the component associated to that particular fuse. Do the easy things first. Check the fuse box, in particular the connections to the ignition fuse. An arc at the prong connection could cause a fuse to blow.
