ServoTimer2 - no output

EDIT: There was a wire fault. Now reading valid values.

I’m working on a quadcopter, and require the use of the ServoTimer2 library. I have already fixed the usual typedef error, but I cannot get it to actually output anything. I’ve boiled it down to the following sketch and connected it to a servo (no motion) and the flight controller (no PWM channel activation). Any ideas on why it wouldn’t do anything?

#include <Arduino.h>
#include <ServoTimer2.h>

ServoTimer2 servo;

void setup() {
    servo.attach(3);
    servo.write(1200);
}

void loop() {
}

Its just an Arduino Uno with the servo attached to pin 3.
