House/Aux battiers won't charge off engine

[Metalman]

I have a 2005 Fleetwood Bounder diesel pusher, The house/aux battiers will not charge off engine. I have looked everywhare for a isolator, diaode or relay. No luck.....Does any body know where to look? If i can not find it, i will change it to a relay.... Thanks for any help.... :) :)

Have you verified that your house batteries will charge off the generator or shore power?

Yes i have, everything works fine,inverter works, charger works fine. Casssis batts charge fine from alt, no charge to house batts. ???

how many cables do u have to the house batts ,, and how many house batts do u have ??? and have u cked the house batts ,, while engine is running , with a volt meter to see if for sure they are not charging ?? just few more ideas to ck :)

I have a "Battery cut off switch" which will not allow coach batteries to be charged by motor. This switch is with other switches on my Monaco near the steps. The volt meter check on the batteries when the coach is running is a good idea. If all batteries have the same readings they are charging. Good Hunting

I found the same thing on my Empress. My switch is above the main door. ;)

Thank you all for the advise, this thing worked fine for three years. I put in all new battiers, boom no charge to house batt. I checked everything but i can not find where they get the charge for house batt from the alt. There should be a relay, isolator or diaode somewhere. can not find it. When i get home will call fleetwood and wiring diagram for this darn thing. If i don't find problem i will put in a relay. If anybody knows where that thing is, please let me know. :) :) Thanks

Hello Harold and good morning, I have the complete wiring for my Fleetwood. I don't know if your will fall in line with mine, I have an 03 Southwind. I can see it to you if you would like to look over it. The complete wiring is 12 pages. Let me know and I can send it as a file to you. :laugh:

H2H1... Thank you, i printed all, may help. I am going to call fleetwood and get a wiring diagram... Thank you again. :) :) :)

[Metalman]

Thanks to all. FYI called fleetwood, talked to service, got wiring drawings of the whole thing.....There is a pc board in the chassis control box that controls the charging system, burned out...I can get one from parts.. :) :) Thanks again

i have the same issue on my 2003 ragle. the circuit board is corroded. american coach doesn't recognize the number that is written on the board, so I'm having a very difficult time finding a replacement.

[Metalman]

sawood...Iam out of town right now, but when i grt home tonight i will give you the phone number of fleetwood parts, maybe you have the same control box as they use. The new circuit board was $155.00 not to bad. :) :)

[Metalman]

sawood...The control panel on a fleetwood freightlner chassis is made by rv components. The replacement pc board # is 087723. The ph # to fletwood parts is 1 800 591-0628. The mod# of my control panel is F73-1042 diesel. I hope this will help you and anybody else. Fleetwool service dept very helpful. Ph# 1 800 816-9825 :) :)

I seem to be having the same issue with my 2002 Beaver, it is new to me but I cannot find that it has a battery cut off switch. Chassis batteries are charging fine. tested the house batteries while running and they get no charge, but do charge fine when I run the generator.... Help if you can please!

I seem to be having the same issue with my 2002 Beaver (figures since Monaco owns Beaver they would be similar), it is a new rig new to me but I cannot find that it has a battery cut off switch. I have a coach power switch and some light and power step switches by the door... . Chassis batteries are charging fine. Tested the house batteries while running and they get no charge, but do charge fine when I run the generator.... Help if you can please!
