Catalina Spa heater not working

Hello, I have a older Catalina Spa. Recently the heater stopped working. I noticed the wires coming off of the relay were burnt. Repaired them and spa started heating again fine. About a week later heat started dropping again. Looked at the wires I just repaired and same thing again. The coating around the wire is turning color like it is about to burn through again. Any advise on what is causing this? Is it the heater or do I need to replace the relay? Thank you in advance for any help on this matter.
