i bought a new one it ran like normal for like 2 weeks riding around the neighbor hood since it aint legal. sso i ran it about evry two days. and now i have to jump it off again. my friends say its my rectifier . i wanna to hear the truth from my f2 boys.

Sure sounds like the rectifier to me, a classic F2 problem. If it is, try and replace it with an aftermarket one that has cooling fins.

Yeah, Krux fuses are gnarly. My ElCheapo doesn't have a fuse on it's 10A testing setup. If you measure current across the battery terminals you will undoubtedly blow your fuse, but the leads won't melt in half like mine would...

You most likely have a regulator / rectifier that has gone bad. Very common on the F2s & F3s. Take your multimeter & set it to DC volts & ckeck the chargine volts at the battery. Should be between 13-15 volts. Any less or any more & there is a problem. You also need to Take your multimeter & set it to AC volts & check the AC vlots coming out of the stator as the stator could be a problem as well.
