Setting with one light over micro wave on. Pluged into 50 amp, batteries will not charge, inverter not charging. Which light in coach do NOT run on 110 ?

2007 Fleetwood Excurtion 39V.
Engine starts OK, will engine running charge house batt?

All your lights should be 12VDC. No lights? Start checking fuses with a VOM. Do you have 120VAC inside the RV? Have you checked the breakers on the pole, inside at the converter?

Everything that runs on 110 TV, DVD, microwave and 110 outlets are working because I have 50 amp service at RV site. Just no other lights working. My 5th wheel had a few lights that worked on 110. I assume motor homes do not.

The inverter is not a charger, it inverts 12vdc to 110ac. Normally the inverter would not be used if you are plugged into shore power. If it is a converter/inverter then check the fuses as the converter is what charges the batteries.

Yes, both sets of batteries should charge from the engines alternator.

All your lights should run off 12vdc, except a light that is in the microwave.

Check to make sure you do not have the "salesman switch" or battery disconnect switch turned on. Cycle it a few times. If that doesn't work you may have a bad battery disconnect solenoid.

Have you checked your disconnect switch usually by entry? Maybe someone bumped it.

He deserted this thread on the same topic.

It most likely a converter problem or battery disconnect switch.

As for your older 5th wheel, many early modle RVs (all types) had a few lights that where 110V. Every newer model RV now uses 12V.

This past summer we found our lp fridge hadn't worked all day when we were away-after a lot of checking noticed the gas detector had shut down-did a voltage check and our house power was only about 3.8 volts. Checked the fuses and wiring all over-no luck. Started the motor home engine and we had power-as long as the motor ran or the batteries were charged.

Turned out the converted was dead-had lost its voltage control first and boiled the batteries and then quit entirely.

Try your furnace or some other 12 volt device just to make sure that it is ALL of the twelve volt out-not just the lights.

But running the motor to charge 12 volt should give you some respite.

RVs normally do not use converter/inverters. You would have either a converter/charger or an inverter/charger.

Too bad the OP is gone. Me thinks all he needed to do was check the breaker that supplies power to his charger.

Thanks for your help.

The next morning I had nothing, no lights no frige. We wound up coming home to have batteries and charger checked out. After coach ran for a hour or two on the 4 hr ride home all batteries charged every thing working normal. I guess I will be replacing batt charger?

It was my understanding that a converter takes 120 and provides 12v and that an inverter takes 12 v and provides 120. (or maybe that's reversed but makes no never mind). Our RV converter/inverter indeed does both as well as charging. So I believe the statement is incorrect?

Yes it is. Some mfg do use a converter/inverter/charger which of course does everything. More common however they use a converter/charger then add a separate inverter. But I believe the former is becoming more popular.

Gary RVRoamer · 03-31-2012, 02:12 PM

You can't generalize very much on this. Whether a converter/charger or inverter/charger is more common depends on what class of RV you are looking at. Most diesel pushers have a combined inverter/charger/converter. And as inverter usage gets more popular, other Rs are installing them too.
