I have a 2007 Monaco Diplomat. The engine does not charge the house batteries, nor does the shore power charge the engine batteries. This is stupid. But that is what they tell me...
An Intellitec module 00-362-100, does the job, the cost is about $55.00 and is easy to hook up....

All the Motorhomes I have (and this is the fourth unit) had so far chage the coach batteries from the engine. My Discovery waits untill the Engine battery is charged to a certin level before switching over to the coach batteries.

I gather from the four pages that:
Some don't charge house batteries from the engine alternator, but most do.
Some don't charge chassis batteries from the inverter or charger, but some do.
I installed a Link 20 on my MH to monitor the house and chassis batteries. My MH has a battery isolator that allows the engine alternator to charge the house and chassis battery. I prefer battery combiners but that is another story.
My alternator charges both batteries.
My inverter will echo charge the chassis battery but not provide float voltage. Go figure.
My solar panels only charge the house batteries after the Xantrex Echo Charge (battery combiner) went TU.
My reason for describing all this is there are many ways of dual charging batteries, my MH has three, so there are lots of opportunities for a failure, and I've had one. The previous posts about checking battery voltage under different conditions will really provide the best answers about what is happening. My Link displays battery voltage to the nearest 100 of a volt plus amps and amp hours, making it much easier to monitor what is happening to the batteries.

I apologize in advance, I have not read through all 4 pages of this thread.
But I have one question to the OP of this thread.
I'm assuming that you have a battery disconnect switch that disconnects your coach batteries when have your mh in storage. I have such a switch and have found out that if I leave the battery disconnect switch in the 'OFF' position the batteries will not charge while the engine is running. The batteries will only charge if the battery disconnect switch in left in the 'ON' position.
You might want to check that your battery disconnect switch in is the 'ON' position.

I have been a Monaco Dealer Service tech for the past 12 years that we have and sell Monaco, including Diplomat. ALL Monaco products including Diplomat charge the coach batteries from the chassis Engine Alternator. You are correct about the optional plug-in module-it is for the Coach system to charge the Chassis batteries while the coach is plugged into 120 shore power. The higher line Monaco's have that module as standard equipment. Doug

To dougrainer, is there a module somewhere that I can check. Over the past 18 months, before and after buying the coach I have talked to probably 12 techs at Monaco. I get different answers from each one. I have schematic from Ty Meirer of Mopnaco showing the BIRD (bi-directional relay delay) Part no. Intellitec 00-362-00 in "Rear Distribution Box", it is dated 2/7/08. I appreciate your comments.

I had several motorhomes. And the Class-C charged the batteries and the last two coaches charged the batteries going down the road. Do you know for sure?

I normally run the generator underway for the overhead AC and to be honest, one of the few times I can run it for any length under load like it needs. Normally I have hookups when I camp or its stored.
Never used the propane for fridge. I prefer not to have propane open underway but just my preference.
I've had low house batteries from sitting in storage many times. I run generator for 30 min to hour and when I'm done, batteries have new life.
If I use the engine underway, much slower and takes longer from my experiences. Genny has proven the fastest way to get batteries back up to par. Can't speak for other rigs but works well with my Southwind.
Since I like power underway, largely those two AC units, I'm forced to run genny so it allows me to enjoy myself while charging the house batteries.
I'm no electrician so can only speak from personal observation and results..

As you have found out, Monaco can give vastly diffrent answers to the same question. That module is mounted on the back wall either in the battery compartment or in the compartment next to the battery comp. You will see a BIG solenoid and that is the solenoid that is energized to charge both battery banks when the engine is On. I have NOT checked 2008 models, but previous models did not use the Intellitec brand BIRD module. Your relay (Not Intellitec) is in that LF storage behind that black plastic cover and is mounted on the BIG fuse board assbly. This module is what controls the chassis engine charging the coach batteries. I just checked the 08 Diplomat and it is using the Intellitec BIRD relay. This BIRD does 2 things. 1. Once it sees the 12 volt ignition signal it sends 12 volts to the solenoid in the battery compartment to bring both battery banks on line to charge both while traveling. 2. IF the coach charge while camping or stored and plugged into 120 goes OVER 13.1 volts and stays over 13.1 volts the BIRD sends a signal to the Solenoid to close and allow the chassis batteries to charge while camped or stored. Once the coach charging system drops below the 13.1 (Float charge) then the chassis solenoid is opened and the chassis no longer charges while camped or stored. This BIRD relay is in the LF storage where the BIG fuse panel is behind the plastic cover. The BIRD relay is NOT behind this cover, but mounted on the wall in plain sight. Doug
