I have an older HS14 unit, my compressor and fan do not come

Customer Question

I have an older HS14 unit, my compressor and fan do not come on, I have replaced the capacitor and the K1 control relay and system still does not come on. If I bypass the connectors 6 and 3 on the relay both the compressor and fan come on and ac works good.
JA: Did you double-check the thermostat? And what about the unit's filters?
Customer: Yes, AC person came by to check the system, he was the one that said the relay was bad.
JA: Do you plan on doing the work yourself?
Customer: If I can get figure out what the issue is and the parts are available, yes, I'll do it my self.
JA: Anything else we should know to help you best?
Customer: That is all for now.

Hello, use the 'add files' link next to your send button to send me a close up, exceedingly well focused photo of the wiring diagram glued to the unit that shows that K1 control relay.

I will mark it up with trouble shooting instructions.
