So my 400ex was running yesterday. But last night I unplugged the rectifier to clean it and see if it was not working because I had battery issues the next day I plugged it back in and it won't start at all. No lights, nothing

Was there a reason you unplugged it? You message is a little hard to understand. If it was working before you took the voltage regulator off then it sounds like you need to go back and see if it is still dirty or if you need a new one. Even if the battery was really dead it will still turn the lights on and the neutral light
