I have an older Thermospas hot tub that was given to us by a friend... it's been a nightmare so far, not knowing all of the problems I would encounter.
Electricians ran power to the tub 2 months ago. Everything "power wise" worked fine. But that's when I realized we had multiple cracks underneath the tub. I finally got around to using Plastaid to fix those cracks. I had the tub flipped on it's side last night and flipped it back down.
This morning, I went out to reconnect the power. The wiring diagram literally says "ground, red, black" plus I took a photo with my phone to ensure I was reconnecting everything properly. Before putting the control panel cover back on (being a PC tech) I thought to try the power first to make sure it turns on. (There's enough water to at least test the jets.)
The tub powered on for maybe 5 seconds then stopped flat. Now it will not power on at all. No power to the control panel either. I checked the GFCI test and also breakers in the house. No luck. I then noticed a 4 or 5 pin connector that was disconnected from the motherboard. The label, I think, said "battery" next to it. I reconnected but still no luck. I went as far as to double-check the ground, red and black wiring connections, but still nothing.
I'm completely new to hot tubs, but have owned a pool for years, and have some computer and electric knowledge. Any suggestions on what to try? I read somewhere else about a fuse, the 2 that look like standard fuses (where you can see the wire through the glass) are OK, but I'm unsure how to test the "Bussman time-delay" to see if that's the issue (which I read it could be on another topic here.)
Thanks in advance.
