i just disconnected the big starter wire from the starter, i jumped the terminals for the fuse with a jumper wire cause i only have 2 fuses left, (i burnt 9 of them), and it started melting the jumper wire.... so i am assuming since there is no power to the starter, as in power wire disconnected, that it is not the starter
there are 2 igntion fuses in the box, the top one says ignition run, the bottom one says ignition run acc.. the one that is blowing is the ignition run which im assuming is the starter fuse cause i dont see one labeled starter
Mine started popping fuses a month or so ago when I would go to start it. I cleaned the grounds at the battery and it hasn't popped any since. Clean all of your grounds even at the block and if it still does it I would say it is likely in the starter.

Oh, man. Electrical issues are always a pain in the @$$. I would try getting a multimeter and check both sides of the fuse holder to ground. Hopefully, you won't have to go all the way up into the ignition switch to find the problem. I'm definitely no expert when it comes to these sorts of things, but that is where I would start. You've obviously got a short somewhere. Might as well not burn up your last two fuses. If you don't have a multimeter, even a cheapo would work just fine for troubleshooting this. You're only looking for continuity. Keep us posted!

ok here is what i got now, starter wires are disconnected, i used my meter to check for continuity from the "hot side" of fuse to ground.. no cont.... i checked the "hot side" to pos on battery.. cont... so all good so far..
now i checked the "cold side" of fuse to ground, nothing, i checked it to positive on battery, nothing.. i turned THE KEY ON... now i have continuity from the "cold side" to the neg on battery and also the posi on battery...
so now im puzzled and confused cause i dont know what gets powered up with this circuit with key on
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.
