bad inverter?

I just got my trailer delivered 2 days ago. When I plugged it in to shore power the inverter was humming loudly and clicking on and off
This cycle would happen about every 10 seconds.
I was told on another forum to charge the battery so I did.
This time it still clicked and hummed but the Lights didn't dim as
They did before. When I unplugged shore Power i have NOTHING.
No lights no water pump no heater no information panel. Nothing.
What is causing this nightmare in my new home? Granted its 35 years old... But still! Any ideas?

    Have the battery checked. You just charged it and then nothing.
    Converter might just be struggling to charge a battery that is shot.

    In a 35 year old trailer I would think we are talking about a converter not an inverter. Check for a disconnect switch as pianotuna suggested and give us more details about your trailer. Good luck.

    Start with the main fuse from the battery. Also look at any other fuses in the 12 volt circuit. The inverter / charger only charges your battery so it can be dead and you will still have 12 volt lights assuming you have charged batteries.

    Solve this problem first and then we can look at your charger issues.

    Terry78,

    Make and model would help. There is often a main battery disconnect switch. It needs to be "on" to allow the battery to be used.
