2011 Rockwood Freedom 1940LTD- Power Issues

Help! Our new to us 2011 Rockwood is having issues with the 12volts. No lights, co detector or furnace working. Power coming in but not going out. We replaced all the fuses just in case but its 100% an issue with the power getting out.

Fridge and outlets all worked when plugged in.

Thoughts?

You have 2 12v sources - battery and converter. When plugged into shore power, the converter (when working) produces 13.1 - 14.4v to run 12v system and recharge battery. When not plugged in, battery produces 12.7V or less to run 12v system - less as battery is discharged.

Check voltages both unplugged and plugged in to see if battery or converter is problem. Could also be a battery is so dead converter shuts down to protect itself.

Thank you- we have never used the battery to power so I assume its an issue with the converter then?

No. If you have never used the battery or recharged it, chances are the battery is dead.

Did the seller demonstrate 12v items working with the unit plugged in? Or did he demonstrate them on battery?

When was the last time 12v items were known to be working?

In your pop-up, the converter and power center (fuses and circuit breakers) are a single unit. Replacing the converter is several hours plus $150 for a new unit. So I'm trying to make sure converter is bad before replacing.

Make sure battery is disconnected. Then plug into shore power. Check all circuit breakers and all fuses. If still no power out then converter needs to be replaced.

Battery needs to be removed and load tested. If good, you saved yourself replacement. If not, you have to decide how much dry camping (no electricity or water) you will do. If you always have hook ups almost any battery will do. If you want heat for 3-4 days without plugging in, you will need 2 golf cart batteries.

Hope this helps
