Trouble with RV Power - need help. In the dark.

hello, my wife and I are RVing in pentwater, Mi. We were having trouble earlier this week with our fridge, and got some great help from you all on this forum...another problem came up this evening. There is no power in our RV. We are pugged into a working shore power at an RV resort. I have a 2005 BT Cruiser and the power stops working in our RV. The RV is plugged into the outlet which is working fine. My battery seems to go dead and the air shuts off. Some of the appliances In the RV work but the the battery appears to being drained. The fuses are all good. The power went out twice and the fist time it tuned back on and worked perfectly. After a few hours it lost power again and does not want to turn back on. I heard a steady clicking sound under the converter panels and it appeared to be coming from Hi-amp Bus. There are 3 hi amp buses and they have buttons that can be pressed in. Could this be the issue - and help would be greatly appreciated. Thank you.

Your thermostat requires 12 volt power to control the A/C even though the A/C operates on 120 volts.

You need to check all the breakers in the 120 volt panel , a power surge may have tripped one . If they're all ok , then you need to find the converter/charger/inverter and look for fuses or circuit breakers on the unit .

Can you run the engine for a while to charge the batteries ?
Do you have a multi-meter to check voltages ?

Thank you skip. The breakers all seem ok and the RV worked this afternoon after it lost power. I will check the converter/charger/converter has probably gone bad just like you described. Are these difficult and expensive?
Thanks again!

Does the generator power the coach?

Usually it does, but the generator will not start after the battery runs down.

Do you have a 'Boost' button on the dashboard that temporarily connects the house and chassis batteries together while holding it on?

Do you have 120v lights or other indication that 120v is coming into the RV? A circuit breaker on the converter/charger might need to be reset.

Thank you Bob and Donna - I have an auxiliary switch in the cab and I will look for a reset button on the converter charger. That's a great idea. - thank you and I'll give it a shot.

Since the power went out and then came back on by itself, it doesn't sound like anything needs resetting. It could be a lose/intermittent 120 volt connection.

I'd try to check the 120v connection at the converter. There's a chance one or more of the wires is not making a good connection.

Hello again and thank you for your help. The issue was the converter/charger/converter which needed to be reset. I reset it and the rv works perfect. Once again the help I received from your kindness on this forum has saved me. Thank you! You are wonderful people and I very much appreciate you.

I'm glad you found your problem .

I'll add some info to the gen set question . Almost all gen sets will not charge the batteries directly , they have only 120 volt output and power the converter/charger to charge the batteries.
BTW. I carry a small 10 amp , battery charger ; luckily ; because I had to rely on it to keep the batteries charged , for three, while I waited for a new converter to be delivered.
