A fuse is in the gun to protect primarily the motor, but is does a pretty good job of prtecting the rest of the system. Removing a fuse to test electrical devices is STUPID, STUPID, STUPID!!!! It's there for a reason. Removing your only method of protection even for a test can be expensive and potentially disastrous.

If you want to test draw, spend the money, buy proper test equipment, get fuses with increasing ratings, or you risk spending your money on replacement parts.

Fuses are not resistors (except current limiting fuses which aren't in AEGs), they do not limit current or affect ROF. Their connection points may do this however. If you find voltage drop across a fuse, that means you've exceeded it's rating and it's destruction is imminent.

For the OP, you can also check your motor connections. One of the terminals may have become disconnected or broken. You may also have a motor failure, switch failure, selector failure. Start with what you feel comfortable with, and if your problem persists, get ahold of someone locally. You have posted up on JOC already, and that's your best bet.
