Thanks for Choosing Just Answer..
Can you tell me what the ser button is you are referring to?
I am pretty sure the Dynasty does not charge the house battery when plugged into shore power. Some Monaco's do but I am fairly certain that the Dynasty does not. There will be a few solenoids, normally the big boy is the house solenoid that feeds power into the interior. Also there is a bi-directional solenoid, and what this will do is allow the house battery to charge when certain demands are met from the alternator. When you are running your engine and the voltage is above 13.3 volts it will allow the house battery to charge.
I have a feeling that is what you might be looking at and a test would be to start the engine and get some voltage readings off of that solenoid. IF the voltage goes up on the chassis post and then goes up on the house battery post (above 13.3 volts) then it is for charging the house battery while driving to maintain the battery.
I would call Monaco Tech Support to find out for sure. Do not want you to replace parts that are not needed. IF that is the case a Trik L charge or echo charger can be installed that will allow that chassis battery to charge when plugged in.
Click HERE and is this what you are looking at? I would call them back and find out if your unit charges the chassis battery plugged in. IF so then it could be that solenoid it would be the only item to allow charge, if not you can add a echo charge to keep the batteries up.
I just don't want you to replace that big boy and have the same issue. I understand what you are saying, you should have incoming voltage, one post going to chassis and one to house. I would see if you can test that by running the engine and seeing if that is opening up allowing power to the house side above 13.3 volts.
Someone needs to pull a print and look for you. I looked at a 2005 dynasty print and there was no indication that it is getting a charge from shore power.
They are probably correct, but I would find out if this model charges, I did not think the Dynasty charged the chassis battery when plugged in and I have seen a few other manufacturers like this as well. And the only thing that can be done is add an echo charger that will charge. I will also see if I can find some more info out..
No I did not receive credit, and you can accept any of these post if you feel like I helped..
Well that is not much room for charging the chassis battery but I guess it is designed to charge when the voltage is above 14 volts which is really never.... The way the inverter works is it charges in stages. So if the batteries were low the inverter would be in a bulk charge and charging around 14.2 volts, not much higher, after the bulk it will go down to around 12.8 and maintain in a float charge. So you can see that chassis battery is not getting charged that much, normally the inverter will charge like that in stages. SO IF you get me the model of that inverter I can find you something, and we can keep going, you been real patient and I enjoy helping out.
Let me know the model of that inverter. I have a feeling you will need an echo charger but lets see if that inverter charges over 14 volts all the time....
You can ask for Robert when you post a question, the other experts should stay out or just tell them you are looking for me.
