Coachmen concord chassis battery charging

[larryhobby]

I have a 2013 Coachman Concord, Class C motorhome, is the chassis battery being charged when the motorhome is plugged into campground pedestal. Thanks in advance

If it does have the ability to charge the chassis batyrry you will be able tobsee 13 plus volts in a meter across the terminals. I have a coachmen prism and it does not. Was not happy w that. I put in a trik L start on mine. You could run a maintained and simply plug into the 110 inside the camper. Will only work when plugged in via the 30amp

Ditto on the battery maintainer . To make things real simple I just use a power point adapter in the dash "cig. lighter" as on mine at least this is on the coach battery system.

No the chassis battery is not typically charged when plugged up in a campground. The easiest way to rectify this would be to get a small charger and plug it into the camper, then when you are plugged up the chassis battery will charge too.

One wire to positive house battery. One to positive engine battery. One to ground.
Done!

I have a Coachmen Freelander and I know the chassis battery does not charge with shore power. Although the chassis charging system does charge the coach batteries when running or driving. So if you are using a maintainer to keep the chassis battery topped off, will it also charge the coach batteries?
While the Freelander is in storage I keep it plugged in with the shore power cord and I keep a maintainer on the chassis battery. But I wondered If the maintainer isnt already charging the coach batteries. Or, why I couldnt run jumpers to the chassis battery so I would not need the seperate maintainer.

Now that is slick... on my mod list.

Thanks to all that replied, I went out this morning and my chassis battery was dead, guess I know the answer, it doesn't charge when connected to shore power. Thank you all so much.

Like it. I Just put it on my spring mod wish list.

Do you have your battery disconnect switch set to ON or OFF while plugged into shore power?

[markb422]

I keep the switch to on. I have not tried it but I read that if the switch is off the alarms will chirp?

[BlackJeep22]

My bad... I missed the fact that you were talking about the chassis battery.

[KAttkisson]

The alarms chirp because the house battery runs down from the long term parasitic loads. ---Alarms--antenna amp. etc. These are disconnected with the battery disconnect.

I will throw this out there. This is what I do since I can plug in easily but I don't want to keep 12 volt power on or 115 on to the invertor. I installed a battery maintainer on both the house battery and the coach battery in the electric box where the "emergency" solenoid is located and there are feeds from the house and coach battery in close proximity. These are $34 dollar 1/2 amp units from Wal-mart with 3 amp fuses. These are permanent hook-ups and are fed by a light extension cord that permanently runs outside for 115v hook up . Throw the house battery disconnect on the way out and plug in. The next time you want to use the camper everything is fresh on both batteries.

My alarm does the same thing. I have had my Coach since December 20. No gas leaks and the battery is fully charged. The instructions on the alarm says the unit needs to be replaced since it is blinking red/green.

Please explain this to me a little more. I am a newbie and I am looking at the Trik-L-Start and I am not sure of what you are saying. Duh...

Maybe...

I haven't checked my Concord because it stays plugged in when I am at home. But on several other units I have owned over the years the battery disconnect DID NOT disconnect everything. On my last unit the fridge control board and the alarms stayed on.

2009 coachman freedlander the switch kills everything including the alarms and the Ref. control board.

The disconnect switch is not usable with 115 volt AC current plugged in. It has to be unplugged for this switch to operate. I was told that this was a Refrigerator safety logic device to keep 12 volts to the ref.

Let me get more detailed with the problem. My alarm does not chirp with the motorcoach running or the generator running. . It only does this when the Coach is on battery. . Looked in the book and not much there. . I read the C02/02 alarm itself. . The light is alternating red/green. . The instructions on the unit itself says that it needs to be replaced when this happens. . I just bought the thing less than 3 weeks ago. Cg

Something to check on the chirping with the symptoms described:
With your generator off and the shore line not plugged in check your battery voltage. I know you state that the battery is fully charged but find out for a fact that it reads 12.3 volts or above by itself. It could be that there is a dead cell in the battery that is lowering voltage to a point that the alarms will chirp. This low voltage would be compensated for by your invertor when provided with 115vAC with either shore power or generator.

Thanks for the idea. . That never occurred to me. . Well, actually that is out of my knowledge base. . I will have to have someone else look at it.
