2005 Damon Daybreak generator will not start.

This is a generac generator. I have tried to start it at the generator while it is plugged in and will not start. I have unplugged it and started the MH and no start from the dash. Also where is the battery control panel?

The batteries used to start the generator are under the steps at the entry door. Strange that it has a Generac, My 2005 has a Onan 5500 Gold. Anyway, There is a battery control center under the hood. It is on the drivers side. You will see two solenoids and some fuses, as well as a black plastic cover plate covering the control board.
First I would check the voltage of the house batteries, under the steps. These are use to start the generator. They should have been charging if you were plugged into shore power for any length of time. I would check with a volt meter without shore power, then with. You should be able to see a difference in voltage. If not, then the battery control center (commonly know as the BCC) is not working correctly. It could be something as simple as a fuse on the board, or one of the relay solenoids. Also, note, if the batteries are really low, the BCC will protect the system from a large current draw. You may need to manually charge those batteries first. Anyway, this should be your staring point. With good charged batteries, you should be able to get the generator started.

Hope this will get you started in the right direction.

Thanks Hawkeye! I will have to do the voltage check with and without it plugged in. I know when I unplugged it the other day I could hear the transfer switch so know that is working. When I did try to start it at the generator I heard no noise at all. I do know the house batteries are working I do have power in the coach when unplugged and it has a 1/2 tank of fuel. The generator does have oil. So there maybe an issue at the BCC.

I found the bcc but not sure how to check if it's working. The house batteries are not charging now. I measured across the 2- 6 v batteries and only get about 5 when plugged in and not. Click image for larger version

Go to files, under Electrical, look for a file named Intellitec Single Disconnect Control Center upload from me. This will give you lots of information as well as some troubleshooting steps.

Let me make sure I understand what you are saying. When you say 5, you mean 5 volts across both batteries wired in series? In other words, you went from the positive on the 1st battery to the negative on the 2nd battery? If you did this, you should have at least 12 volts or better. If you only had 5 volts, there would not be any lights or not very bright lights on the inside when unplugged from shore power. If you went from negative to positive on each battery, and you are only getting 5 volts, you still have a problem. 5 volts is to low, even for one 6 volt battery.


Sounds like you are having a problem on the BCC. Just follow the steps from the downloaded file. If it were me, I would do a manual charge on the house batteries, to see if they can take a charge. If they are really old, they may not take a charge.



You stated the voltage never changed with shore power plugged or unplugged? Then start the engine, and if the house batteries are as low as you say, you should see at least 13.1 volts on the volt meter. If not there is a problem with the BCC.

It could be something as simple as a fuse or one of the solenoid relays. Both can be bought on Amazon.

One note: That silver solenoid is very warm to the tough at all times. It is a constant energize relay. If it is not hot or very warm, then something is wrong.

The black solenoid is the house battery disconnect.

I can see that its a latching type by the extended bottom.

If that's not connecting, you may not get any charging to the batteries. See if you have house battery voltage on both sides when the disconnect switch is pushed to " Use "

Thanks Hawkeye! I did download the file I will be checking it out this weekend. Yes I did measure 5v across both batteries. I agree I do think the BCC has an issue.

Where can I find the 2 -30amp circuit breakers? I may need to reset them.

What type of circuit breaker? 12v or 120v? What is the breaker used for? Some more info and we might be able to help. Also, a good search on the internet might yield what you are looking for.
Did you put a charger on the batteries? I would do a manual charge first, so you do not do any more damage to the BCC system.

Hope the download helps. Good luck and let us know what you find.

I was looking for 12v circuit breakers coming from the converter to the BCC. I have not tried to charge batteries separate from the MH. My charger is in my MH in storage. I did take some voltage measurement on the BCC. There is only voltage on the chassis battery side of the BCC. No voltage on terminal "I" and "S" of the lower relay. The upper relay is cold to touch. Does the BCC need voltage from the coach batteries to operate correctly?

I'm now trying to charge the batteries with a 150w solar panel to see if the batteries will take a charge. This may take 2 days due to the weather. The panel is putting out about 15v on a cloudy day.

Sorry I can't help you with that one. I have never had to look for circuit breaker from the converter to BCC.
But, I do have one important note I forgot to have you check. I the battery disconnect switch turned on? It is the one located next to the entry steps. Right below the 4 light switches. If that is not turned on to battery position, neither your house or chassis batteries will charge from shore power. Now the chassis batteries will charge from the engine running, but no power will go to the house batteries. This is the very first step.
Power to the "s" and "I' terminal are supplied by the "Aux Start Switch" in the coach. It is on the row of switches under the headlight switch. You would have to have someone hold the switch while you take voltage reading.

As far as that silver relay being warm/hot, check it with the engine running, or shore power hooked up. Mine stays hot, because I stayed hooked up to shore power all the time. Plus, I have checked when the engine was running. That not being hot/warm may be due to the battery disconnect switch or the two 30 reset breaker you are looking for. I would look under the bed, and see if you can see these breakers or close to the BCC Board. This is what the 30 amp Type III breakers should look like. https://www.amazon.com/Bussmann-CB25.../dp/B004AH6N3M I have never looked for or seen these breakers. But, the BCC material says there are two.


I would make sure the batteries will take a charge, check the Master Battery Disconnect Switch by the door, and look for the two 30 amp breakers. "I would like to know where these are myself) if you find them. One last important note, I"M sure you already have, check all the CB on the BCC. I think once you check all this external stuff, then you can test the BCC according to the steps in the downloaded material.
Let me know how things are going after you check these items.

Looks like the coach batteries are dead. What is the best way to pull the batteries from under the stairs. They do not fit through the opening. Do you just add a long strap and lower them from above. That seems to be the best way I can see.
