Balboa spa pack with a stuck relay.

Описание к видео Balboa spa pack with a stuck relay.

I should start by saying, if your not trained, don't do this. There's enough voltage to kill or hurt you. When you test to ground the metal tube becomes energized. So, dont do this, just look and understand. Checking a hot tub spa pack that is overheating. There are two 120v relays for 240v heater. What it looks like when one leg is stuck.
