So the snows in Bay City, Michigan have retreated and I went to visit my 77PB yesterday ....

and the batteries were deader than door nails ... I didn't get around to disconnecting the batteries in January as I had planned

I pulled the engine battery out today and am slow charging it overnight before putting it back in on Sunday ...

Any tips to getting it fired back up???

I understand that the engine running will eventually charge the house batteries. Is that correct.

If I can get the Generator running with a charge from the engine, that will charge up the house battery, right ...??

Suggestions and tips gratefully acccepted. Good natured mockery is par for the course ...!

I am so glad you are are there for me ... to help me and remind me of my many failings .. Smile

Yes... once the "truck" starts it will start to charge the house. you might want to check the water level in the batteries first. and hope that they did not freeze. I will be replacing my house batteries this year as they froze. Sad next year they come out when the coach gets parked.

If you have the correct deep cycle batteries in the house position(s), yes they will be charged by the the main engine generator but it is going to take a long time. Those type of batteries do not take a charge at the same rate that the engine starting battery does. Also they hold a bigger charge.

So unless you are going on a trip and driving for the next two days, I would suggest that you put a 6 to 10 amp battery charger on that battery(s) and leave it there for 24 to 48 hours. I am assuming that your charger will trickle down to a lower rate as the battery charge level comes up.

A second option is to just plug in the coach and let the converter charge your house battery(s). If you have an original converter I would be careful not to leave the battery(s) on charge too long. I would start with 1 day and then take hydrometer reading to see how much charge your batteries contain. Based on that I would charge some more if necessary.

Do not forget to check the electrolyte level and add distilled water as necessary. I am also worried that you might have frozen and broken the batteries if they were not stored in a charged state over the winter. So look closely for broken battery cases.

To add to what Ken said, I have been cautioned to not charge a dead or nearly dead battery with the engine alternator. The theory is that the alternator will be working harder for longer than it normally does for charging a starting battery that is in good shape, and can overheat. You SHOULD recharge your house battery(ies) with a battery charger , which could be the coach converter running off the Onan. But, as Ken stated, it will take a long time.

When they are that dead, slow is the way to try to bring them back. I prefer the 1a type battery minder if you have the time. Probably several days each. When done, it goes into desulfonate mode. There is a good chance frozen electrolite has warped the plates and you need new batts if dependability is important.

would there be any plus or minus in running the genny in this case to charge battery?

I have original buz box. I understand it does not self regulate. I go by the uneducated opinion that when my buzz box is running I need house lights on as a small steady drain to offset the unregulated charge. Am I dreaming? does this help ?

this is about the buzz box
http://www.gmcmhphotos.com/photos/g4507-buzz-box-converter-problems-and-replacement.html

nothing really helps, but to change it out

the combiner is the best (automatic) way to charge the batteries (all of
them) from any source

10 minute job,
and you will not forget to remove the jumper

If you are saying run the Onan generator instead of plugging in that should not make any difference as your buzz box would still put out the same voltage.

Turning on the house lights is also not going to "offset" or in any way"regulate" the charge.

Either replace the buzz box with a smart charger or unhook it and use an external charger that doesn't put out the high continuous voltage.

How did I know that Gene would try to sell you a combiner which has absolutely nothing to do with your question or charging the house batteries in your situation?

I would not bother trying to charge with the Onan. It will still take days. Plug in to commercial power to charge it or let the engine alternator do the job if you are going to be traveling. These house batteries are not going to take a lot of charging current for very long. After that it is a slow process.

The OEM converter is regulated at some where around 13.6 volts. That is not high enough to quick charge the batteries and but still too high to leave it connected for days on end. The converter will not drop down to a trickle as the battery reaches full charge. So that is your exposure ONLY after days of being left on charge with a converter.

I still say a 6 to 10 amp trickle down type charger plugged into to commercial power is your best bet to bring those house batteries back to life.

I don't sell anything

the question was about the buzz box

I hate doing it every year, but now that I'm living on a more frugal income, I've come to the conclusion it it more than worthwhile to take every seasonal use battery I own (7!) and carry them into the basement for the winter. I've gone from buying on average 2 or 3 batteries every year, to maybe 1 every other year, a big difference. It's much easier to remember to throw the trickle charger on them down there as well.

for your question of getting it fired back up after the batteries are charged: I usually check:

engine oil
on top of engine and around exhaust for mouse nest
coolant level
while I have the air cleaner off looking for mice, I have a squeeze bottle with gas in it to fill the float bowl in the carb
Make sure the fire extinguisher is near by
Then I fire it up, look for leaks, and let it warm up.

After that is tire pressure, fill the bags up, etc.

I would say that a good converter running from the genset, would charge as well as from shorepower.

Use of the Onan's puny INTERNAL charger capability would indeed be an exercise in futility!

I agree with those who suggest throwing out the boat anchor (aka buzzbox) and replacing it with a modern multi-stage charging system (I used a Progressive Dynamics PD9245C box that I picked up for $126 delivered). Probably the best update per $, other than maybe a macerator. I went over the PO's receipts, and he was replacing batteries at least once a year (and they were cooked when I bought the coach). Now they should last for many years before needing to be replaced, which will more than pay for my new charger almost immediately. I also noticed that the 12VDC power in the coach is more robust when I'm on shore power. And hey, getting rid of the buzzbox trimmed my coach down from 12,000 pounds to a svelte 11,960 or so. Wink

The Onan and converter combination will charge the batteries but it is a matter of time and fuel. The 13.6 or 13.7 volt output will take longer vs. a normal plug in charger or using the engine alternator.

The cost of fuel at $3.00 to $4.00 an hour to run the Onan vs. a few cents per hour to run on shore power is a real difference cost.

I wasn't suggesting firing up Onan just to
run the converter/charger but that the
charge time should be basically the same
regardless of the source of the 120 VAC.
