Installed a new heater assembly. The old one was trashed. Everything is up and running. Back to normal. Thank you my Canadian friend

I'll update once completed. Thanks for your help sir. You're a gentleman and a scholar

I turned the unit on for longer and it did show the heating LED on the top panel. At first it was flickering quickly, then it went solid. Then I did read 240 volts at the heater terminals. The heater did have continuity. I have ordered a new heater, I sincerely hope that is all I need

No burnt fuses. They all have continuity

The light on the control panel nor the circuit board is indicating that the heater is being sent power. Could it be that there needs to be continuity? The heater isn't hooked up. Sorry I'm a mech engineer, not an electrical.

According to my multimeter, I am getting 0 VAC at the terminals. I dont know how that is possible because there was electrical arcing there before I disconnected the heater.

Should I just buy a relay too when I buy the heater? Hopefully relays arent too expensive. When I disconnected the heater, everything else on the tub was working correctly. Also, thank you for helping me.

Yes. I was replacing the upper control panel. The buttons weren't working. This does not have a salt system. It is just quite old. I removed the terminals and they looked nasty underneath. I dont have a multimeter. The free one I got from harbor freight is broken. When I test am I using AC or DC?

So I just replaced the control panel on my Windsor 3 hot tub. When I flipped on the power there was electrical arching at the spot circled on the photo. It appears to be the heating element. I'm wondering what I did wrong. I did not touch any wiring in my work. I simply unplugged the control panel and put a new one in. Please help
