On RNAV 35 at 1400 feet I lost VNAV on approach. I continued down to next step down altitude which was 600 feet. At 600 feet; as I was searching for the runway I continued to 480 feet. I received a low altitude alert from Tower. Because I didn't have the required flight visibility I immediately started to go around. The go around and divert all went normal. Next time when my approach equipment degrades my approach I will go around and re set up for new approach.
Piper Arrow pilot reported a low altitude alert after losing VNAV on approach and descending below the Minimum Descent Altitude.
