Need Inverter Info.

I have a '99 Pace Arrow and no knowledge about the electrical side of the thing.
Problem is Last year everything worked great, this year brought down from storage and had to jump start it.
I got home and plugged into the house power and a battery charger for 12 hours, left the coach set for 3 days, checked everything out and got ready for a trip, when I went out this morning everything was very dim and would not even turn over, just a click., I tried the emergency Start and nothing there either.
Yesterday before I locked up for the night I checked the power on the control panel and both the main and aux. showed peak power. today -very dim.
Question: shouldn't the house batteries and possibly the start batt. both charge when plugged into 120?
Also I don't know what the purpose of an Invertor is, can someone explain in words I can understand?

House battery runs everything inside the house. Coach/start battery runs everything on the chassis. usually when plugged in only the house battery is charged.

Sounds like one of several possible problems. Battery disconnect not done, bad battery, or bad connections.
Some systems will charge the house batteries and then switch and charge the starting batteries but a lot do not.
Do not get caught up in the words used to describe this unit in short they preform two functions. One change AC into DC to charge your batteries and run the 12 volt
system in your MH. Second change DC into AC when you are not connected to shore
power so your AC requirements are met.
The above is a basic idea of what goes on .

The inverter uses 12 vdc to make 110 vac so you can power your tv and other items depending on your coach. The batteries will discharge just setting in storage and may not recovery if discharged to deeply. There are a ton of articles or post on this web site about batteries, just do a search of batteries

Larry- you will need to supply more info to get an efficient range of help, which is easy to get here on iRV2. With what we know from your above post, there are way too many unknowns to start offering diagnosis options. You are in the right place, however, and should be able w/help to get to the root of your problem using iRV2 as a tool in your kit.

+1 on what EcoDriver05 said, inverter uses 12Vdc battery supply to make 110Vac for plug-in appliances.
Your coach may have one in addition to the OEM battery charger setup. Or you may have an RV inverter which ordinarily combines battery charge function with an inverter. A separate inverter may have been added by previous owner or by Dealer on original sale, or by OEM, and each setup may have its own quirks.

Since you are learning your rig's sertup, start by making yourself a diagram showing shore power plug, cord, whatever the cord ends in in the coach (transfer switch box to choose between cord & generator maybe?), from that device to RVinverter/power center/whatever, etc. This is called a On-Line diagram, and doesn't need to be fancy, just as complete as you can make it. Don't worry if you don't understand the parts, just put them in their place on the One-Line with the most info you can take off their labels. Once you post that sequence here, you will probably find other Pace owners who have a similar enough setup and have had your draw-down problem so that you can get good ideas for diagnostics.

Also, I believe your Pace Arrow was a Fleetwood product, and you could close this thread w/a note that you are moving the query to that Forum. Other Fleetwood owners hang out there more so than on this general Class A forum, and can offer more targeted advice.

Allowing the batteries to discharge fully and stay that way may have ended their useful life. They should be fully charged and tested with a battery tester.
12 hours of charge may not be enough to fully charge the batteries, depends on their capacity and your charging system.
Most RV batteries live a long and useful life, some are murdered.

According to the 99 Pace Arrow Brochure (http://fleetwoodrv.com/frvlibrary/do.../1999_pa_b.pdf), you have a converter, not an inverter. Based on the description in the brochure, the converter is built into the AC/DC distribution panel. Battery disconnect switch must be ON to charge house batteries. Unless a PO changed your system in some way, the converter does not charge the chassis battery.

Converter - Converts 120VAC to 12VDC; Supplies 12VDC to coach systems; Used to charge coach batteries. Your original converter was most likely a single stage design that is known to boil batteries dry (check battery water level). Modern day replacements are 3 stage converter/chargers.

Inverter (not originally installed in your coarch) - Used to convert 12VDC to 110VAC; There are Inverters and Inverter/Chargers. For add-on's that already have a converter, the user normally just adds a Inverter. Higher end and large rigs typically came with Inverter/Chargers. A Inverter/Charger replaces a converter. Not only does it produce 120VAC from 12VDC it also produces 12VDC from 120VAC for coach 12VDC loads and Coach Battery charging when on Shore/Generator Power.

You need to get your batteries checked first to determine if they are the source of your problem or if it is something else. Being run down overnight either indicates they are bad or something is draining them. Being drained like that also harms the battery (shortens life). When hooked to shore power, the original converter should be producing around 13.6VDC.

I beg to differ - all Fleetwood brand coaches will charge the chassis battery from shore power via the converter. The gas chassis coaches like the Pace have an RVP Battery Charge Controller that manages that function. The diesels have either the RVP BCC or a more sophisticated Intellitec BCC.
