Hello allI have an issue with my power, and go figure, we are heading out on vaca next week. When plugged into shore power (battery disconnected) my power cuts out and turns back on constantly. I know the power shuts off completely b/c the LP detector chips each time. I hooked the battery up and the lights just flicker. I have been running a small dehumidifier for the past three weeks with no issue plugged into shore power and no battery. A buddy said the battery has to be hooked up for it to the converter, even when the shore power is connected. My question is did I kill my converter or is this maybe a grounding issue? I have a 2003 26' Fleetwood QS.

On and off suggests a self-resetting DC breaker is at play. But shore power is on, so what DC load could be over-loading that breaker for amps?Is there an inverter in the mix? Does the inverter draw too much DC 12v even though there is 120v from shore power?

On and off suggests a self-resetting DC breaker is at play. But shore power is on, so what DC load could be over-loading that breaker for amps?Nothing really, a few LED lights. I turned the breakers off for all the other big ticket items. Left the main 30 amp and the house 15 amp breakers on.Is there an inverter in the mix? No the panel only says converter. Does the inverter draw too much DC 12v even though there is 120v from shore power?

No, the converter should supply a steady 12 volts without a battery.Yes, the converter is probably shot.May as well post the converter model number for best suggestions. And do you camp off-grid wanting a fast charge from the generator?BTW what is the battery voltage as it sits disconnected?

A bad or totally depleted battery may draw more than what the circuit breaker can handle. Charge the battery disconnected from the RV with a manual charger, have it load tested. If it tests OK, connect it and try your shore power again.
