No Shore power

[flip418]

2015 Keystone Cougar 330RBK that will not power up with just shore power. I assume the inverter but I’m unable to locate! Help!!

“..l will not power up with just shore power. ”

Do all 12 volt items work from battery power?

If you remove the access panel in the storage compartment on the side facing the hot water heater, you will see it mounted to the floor. Mine is just past the vacuum canister installed in mine

The above was copied from the keystone forum

Possibility is bad wired (short) connection.
I would cut gfi breaker off and then cut it back on. Do the same with all other breakers.

Late model converters have reverse polarity fuses. They could be in the 12 volt DC distribution panel commonly located adjacent to the 120 volt AC circuit breakers behind a metal plate hed on by a thumb screw.

Understood….not an electrical genius obviously!

Let's get our terms down.

The converter charges your battery and converts 120 volts to 12v.
A inverter takes 12v and boost it to 120 volts.

All receptacles work…I’m thinking an in-line fuse that charges battery from pedestal? We were hooked up to 50 amp but after a few days we had no lights because battery was dead. I know the lights are 12 volt…we had microwave at the time but no fridge

Converter are qite often located adjacent, in back of, 12o volt power distribution panel.
Does any of the 120 volt items work? receptacles?

Where would converter be located?

There was power from pedestal and microwave had power. The new battery did not seem to charge and I had to have a battery charger on it all week. Cannot tell if inverter was running because I can’t locate. I checked all possible breakers and fuses that I can find.

Need more bread crumbs OP….

Or, just maybe, your battery disconnect switch was inadvertently turned off? That would be for the 12V side.

You need to verify power is actually getting to the trailer. The pedestal, your power cord, your internal breaker, etc. Voltmeter is a necessity.

Does anything 120 vac work inside the trailer?

Do you have generator prep with a transfer switch? Those transfer switches are a known problem.

1. - Is there power at the pedestal (or wall plug)?
2. - Breakers?
3. - Inverter changes battery power to 120volts.
4. - Is converter (battery charger) running?
5. - Does Microwave or any of the outlets operate?
6. - is the red button on the GFCI (usually in the bathroom) sticking out?
