Lost all Electrical

[Dlvgolf]

Need some troubleshooting ideas. Here’s the situation:
1. Sitting here in a park with full hook-ups.
2. AC on, nothing out of the ordninary on. No toaster, microwave, hair dryer, nothing like that. I was just sitting here reading.
3. Lost electrical.
4. Can turn on inverter and get power to those plugs.
5. No power anywhere else.
6. Can NOT start generator.

Here’s what I’ve done.
1. Checked electrical box, power is good into my electrical tester.
2. Unplugged and replugged RV into electrical tester.
3. Turned breakers off and back on in RV.

I have no idea what the problem could be. What else should I look at, check, test, etc?

My first guess, and it's a guess, is the Transfer Switch.

Do you have a Surge Protector / EMS that you are plugged into?

When you say "checked electrical box" you mean the you checked the shore power pedestal for power? When you say "replugged RV into electrical tester" you mean a Surge Protector / EMS???

Yes, I have a surge protector. Reading on surge protector say power is good. I unplugged surge protector from site power box and plugged it back in. I unplugged RV from surge protector and plugged it back in.

Update:
Was checking some things.... turned off inverter... won’t turn back on. Also, no indicator lights on fridge. Hope it’s running on propane.

But did you bypass the surge protector and plug the RV directly into the shore power pedestal?

I mean you may not want to do that - but you need to know if the surge protector is the problem or not.

Tried that. No impact.

Tried to start generator at the generator. No power to start it.

No battery power to turn generator engine over?

Generator won't crank at all or cranks and does not start?

A sudden failure under load (AC was running) could be a loose connection in the transfer switch box that was overheating and finally failed. This is usually obvious when removing the cover and viewing the connections for any that the insulation has melted back from the 30 amp wire connections and the copper wire exposed will be damaged. You cut back the wire to where it is good and reattach tightly ( of course with shore unplugged, generator off, and inverter off ). More complicated if there is not enough spare wire to cut back and reattach. The same thing could have happened on the 30 amp wire connections in the breaker box that connect from the transfer switch.

Does sound like Transfer Switch. If you unplug from the shore power pedestal completely does the generator start then?

OK. Update
In turning things on and off, I inadvertently turned off the coach batteries.
With them turned back on, I have normal operations as if unplugged from power.
Generator starts, inverter works, etc.
Still no power from post.
Everything powers fine with generator running. Turn generator off, no power

Glad you got some level of power. For the future, most modern RV fridges require 12v to run on propane. The 12v keeps the propane valve open, and if no 12v, no propane. There are a few exceptions but not many. Safety feature. If your fridge display and interior light are not working, you probably aren't cooling.

When your generator is running do you have full AC power to the RV. If the problem is your transfer switch you may not.

Also, with the generator running you will not receive power from the shore power pedestal. The transfer switch will only provide AC power from the generator when it is running.

Can you test your power pedestal independent of the RV's power cord. Can you plug in a 50 or 30 amp dogbone that converts down to normal 15 amp power? If you can then you could connect an AC extension cord into the power pedestal and then use that with a hair dryer or other household AC appliance to verify power from the power pedestal

Final Update:
Took the transfer switch cover off, found a fried wire coming from the post power.
Thanks for the help.

Glad all is well! Interested in seeing an image of that issue...
