I have a 2004 Monaco dynasty and can't seem to get power to the coach. Even with gender in the microwave clock comes in but nothing else works. I have tried the battery cut off switch inside but to no avail
Make (other): Monaco
Engine: 400 cummins
Tried battery kill switches, but no power. Tried gender on and plugged in as well
Hi: Thank you for coming to Just Answer with your question. My name is XXXXX XXXXX perhaps I can assist you with this issue.When you say "no power" do you mean the 12 VDC side or the 120 VAC side or both?
Are you plugged into shore power? And when was the last time you had the batteries load tested and checked for shorted cells? This needs to be done at least once a year. Do you have a small multimeter so we can do some testing? If not, those are available at most automotive or hardware stores for about $15 or so. I would get a digital readout version. These are easy to use and come with instructions. Get back to me and we can sort this out. R.J.
I am plugged in now. I have a multimeter in hand but need to know what settings to put it on. Also everything seemed to be working fine before I washed the engine compartment
Good to know.............we can start with some AC tests first. Set the meter for AC volts on the 200 scale. If you have auto ranging then it will set automatically. Go to the main power panel where all the service breakers are. You want to use the red lead on the breaker and you do the wire coming out of it. The black lead goes to a ground there.............which will be the copper wires OR the metal on the box. Check each one. You are looking for about 120 VAC give or take a few volts. I am wondering if you have the automatic transfer switch in the engine compartment? That is where the shore cord and the lead from the generator come together. Do you have any power using the genset? And when were the batteries load tested last?
It is dark now. Are you available tomorrow?
I will be around most of the day............get back to me when you can. R.J.
Will do RJ. You have helped me before and I enjoy dealing with you. I will have a good tip for you when were done. Thanks again
You are welcome..............I will watch for your post tomorrow. Have a good evening. R.J.
Just checked main panel inside coach and the is power going to all breakers. I am guessing the battery disconnect switch is screwed????
The microwave seems to be the onle thing that works
I thought power was going to all breakers? Did that change? Is the inverter/charger on?Perhaps..............take a DC voltage reading on BOTH sides of it. If you are hooked into shore power you are wanting to see about 13.7 VDC. This is if the charging side is putting out the correct voltage. R.J.
What else should I check?
Did you see my post before? Is the inverter/charger on or not? And you said all the breakers had power.........did that change or were you referring to 12 VDC breakers?
Are you still there?
Yes...........did you check the inverter/charger and see if it was on? When you said you had power to all the breakers earlier.......was that the 120 VAC breakers OR the 12 VDC breakers?
Yes the inverter is on. The breakers had Ac volt going to them. How do I check the DC side?
Put the meter on DC volts and put it on the 20 scale. Take a reading at the batteries with the shore cord plugged in and you should see about 13.7 VDC there........give or take a tenth or two.
there seems to be no volts at all on the coach batteries. There is 12.7 on the chasis batteries. Coach batteries are 4. 6 volt tied together
Is that 4.6 on one or taken at the cables coming off them? The inverter/charger may not be charging them. You did say it was on? What is the make and model of that unit? And when were these batteries last load tested? R.J.
i meant there are four 6volt batteries connected together. Coach is a 2004 Monaco dynasty. I unhooked all the batteries and there is no voltage reading on Any of them. With multimeter on 20 there is no reading. Batteries were working fine a month ago but haven't been load tested in a while. Shouldn't interior lights etc work when it's plugged in even if the batteries are dead? Is there a different setting in the multimeter for 6 volt?
A DC volts reading is all you need...............sounds like you need to have them load tested.Are you sure they were hooked up right? Easy to get this wrong. Are these in a "square" formation or a "line" formation? I may be able to come up with a diagram that would help.R.J.
i unhooked the batteries and hooked up a battery charger to the main and all is working but the coach will not start. Is this related?
all is well now. Coach is running. Batteries were totally dead so somehow they are not being charged. Is there a way of testing the charging of the inverter
Yes..............with a meter. On shore power you should see about 13.6 VDC at the batteries if it is working properly. Be sure it is on. Perhaps............the first thing is to get all the batteries installed correctly and in good shape and then we can address the charging portion. Again.........are they in a "square" or "line" formation OR are you sure you have them connected correctly? When the batteries aren't any good nothing works right. R.J.
ok thanks RJ. I am trying to rate you but it's not letting me
You have to hit the "accept" first............then it will. Glad we got to the bottom of the issue.Please get back if you need more later. Thanks for being such a good customer. R.J.
Where is the accept button?
On each response.............there should be one or something that asks you to give a level of satisfaction. They are experimenting with a new system.
