I have a older Sequoia spa, no longer made for decades. It has always worked great for me. Seats 4 people. Has no micro processor, all relay controlled.
I can not get the main motor to start when depressing the vacuum start switch. Has 220 volts coming in. Both bubbler and underwater light works.
If someone can tell me where I can get a wiring diagram I would appreciate it. Model # SL 650
