I'm having a problem with the MPEM (Multi-Purpose Electronic Module) Fuse Blowing.  I recently replaced the battery and replaced the plugs.  It started fine and then the next weekend it started blowing the 20 amp fuse.  When I turn the key to the ON position the fuse will blow and no indicator lights flash on the dashboard.  Any ideas or tips would be greatly appreciated.  Just put on new tires and haven't been able to test them out.

Thanks  

You definitily have a short. Check any and every wire along the frame, make sure they arent rubbing metal to metal
