You definitly have a short somewhere. It has to be something that is drawing a lot of current to blow a 40a fuse. First off, I would check any electrical devices that could draw this much current, i.e., starter, starter solenoid, and fuel-shutoff solenoid come to mind. So you removed the red 12v power cable going to the starter, which is coming straight from your battery, and the fuse still blew, correct? Also, disconnect both this cable and leads going to the starter solenoid at the same time, and try again. I know when the starter shorts, it can also fry the fuel-shutoff solenoid. I would also try disconnecting the fuel-shutoff solenoid, which draws a lot of current, and then try again, it is possible the fuel-shutoff solenoid could be shorted and is sending current back thru to your ignition circuit.
