I went to turn On my HTR 6090 and it would not power on I did not hear the klick of Circuit breaker turning on. I disconnected all wires and connectors and tried again but no avail. Does anybody know of any tricks or other things I can do to test this unit out I don’t believe there’s any internal fuses seeing it has a circuit breaker. I do have an extra power cable which I did try but again did not do any good. Any help or insight into this would be greatly appreciated thank you so much
