Boy, a name would sure make me feel like I was attempting to help a person...

What do you mean "combined voltage"??  Did you connect the two new batteries in series and measure the voltage or something else?

Could you post a photo of what you have and the connections?

I can't keep buying stuff. So when I disconnect the positive I get 12v back. However I'm. Showing no amp draw

So when you have the batteries hooked up, and you are measuring voltage of the batteries at the battery posts, you were getting 2 volts, but when you unhook the positive cable from the batteries, and measure at the battery posts, you then get 12 plus volts?

Sorry my name is Anthony. I'm not sure how to post pictures from my phone. Coach Neg is hooked up to neg on battery then the positive to the neg On next battery then positive to pos. on coach

Prior to trying to start the genset everything g was at 12v all wired up

Nice to meet you Anthony!

It sounds like you have this, which is correct.
(https://www.batterystuff.com/images/knowledge-base/Series.jpg)

You say you had 12 volts. Is that exactly 12 volts?? Because, that is basically the voltage of a dead (state of charge) battery bank. The voltage should be up around 12.6 volts with these new batteries (id fully charged).  Have you charged them?

Well, I am stumped.  I cant imagine any circumstances under which these things could happen.  Hopefully, someone more knowledgeable will come along and be able to help you.

What voltage do you get when you measure the voltage of each individual battery on its posts?

No I had 12.4 and someone said they were not fully charged so I went to charge them and all hell broke lose

Other than the generator not starting what else happened?

You may find this chart handy.

I'd start tracing the wires back to the generator and see if there is a short. I'm surprised your rig isn't on fire though with a voltage drop that large.

Nothing I have no 12v power in the rv from the new battery's. I'm following then wiring but it goes thru the dust box thru a bunch of boxes and silver relay looking things. None of which I get

When I hook back up the old 24dc I have power again ND the voltage on. This battery is at 12v +

It was the wire between the two battery's. The old one was 2 gauge and really old. I used a much smaller wire and jumped and all it working well even the genset started....... what gauge wire should I be using to jump theses

Guys thanks for all your help. I feel I have been especially snippy lately due to a very bad week. Hopefully this issue is behind me. Thanks again!

I use the 4 gauge starter cables sold at every auto parts store or hardware store. If you plan on having big loads on the system though, you may want to go bigger.

That bad wire may be why it seemed your old setup was only working on one battery.

No worries Anthony, these scenarios stress us all to some point - very glad you got it sorted.

The heaviest load your house batteries are likely to see is your generator starter or engine starter (assuming you have a cross-feed switch, etc.). Since the cable is very short, I'd think a #2 or #4 would be fine - just guessing without any real facts though.

Where are you measureing the voltage at.. If you are measuring AT THE BATTERY for all voltage measurements then the dump to 2 volts under load indicates either some serious load or some serious internal resistance (Or a bad jumper wire)

If you are measureing remotely... Then the 2 volts most liklely is indicateive of a connection issue or bad wire.

I had a bad wire once. No load it measured 11.x volts (Batteries were 13.6, floating)...

Just the volt mtere 20,000 ohms per volt, 20 volt range (400,000 ohms) was enough to drop it about 2 volts..  That was a bad wire

Test lamp took it to zip... (more like 2 ohms)  Traced it, found the bad spot. excized it, and 13.6 under load happened just like that (l.oad is 3 amps plus on that 10ga line).

I am .measuring at the battery. Also last night I heard the refrigerator kicking on and off last night. As it's using propane what is it doing?

I'm starting to suspect the 2V reading was a meter error of some sort...bad connection, dodgy lead, or something of the like. 

(or-- and we've all been there, one of them I D ten T errors...)

Same as it does on 120vac. The only difference in operation is the heat source. Just what is it you are hearing? An absorption fridge is silent unless you have fans either inside or out back on the cooling unit. Then you may hear the fans cycle on/off.

If you hear gurgling when the heat comes on and the cooling unit goes to work, start saving up for a new cooling unit.  :'(

Not always true, you can hear the flame come on and off when it cycles also, mine is actually quite noticeable.

It's just a click. Almost like relay or something. Only reason I even heard it was I was sitting outside by the fridge. Also I checked the voltage now AMD it's at 12.47 which is up from this morning. Does the cold weather have anything to do with it?

Mine clicks when I turn it on, I'd imagine it does when it cycles as well but I've never heard it. That's not saying much though. I don't hang around the fridge too often.

As far as your voltage goes, if when you woke up and used the bathroom/water pump the batteries would show a voltage drop and creep up after it rested for awhile so that could be normal that your voltage was higher later in the day.  To get a true reading of a battery's voltage it should be at rest for a few hours. If you are using it, it will always show a lower voltage than it would if it was resting.

If your power needs are truly as low as you say, once you are able, a 100 watt Renogy solar kit on Amazon for $180 would be well worth your while. You would likely not need to run your generator ever.

I have 200 watts of solar with the same batteries you just put in and it has never been plugged in since I put the solar on. I camp exclusively at high elevations in Colorado, don't need A/C and I have an oven, so I just chose not to use the microwave, plus I like stove top popcorn better.  The 200 watts is more than enough to charge the batteries to full by early afternoon after running the furnace, led lights and stereo all night.  Usually it is charged up by noon. I use a Victron battery monitor so I know my exact state of charge without relying on voltage measurements.

A click is normal. Two things occur when the flame cycles on: (1) a solenoid opens the gas valve, and (2) a spark is generate3 at the igniter. Both involve a "click", but usually the igniter is what you hear. After that, there should be no sound, since the LP flame is too small to make any noticeable air-sucking noises.

Good idea on the solar I might look into that. Well today still at 12.48v well see how things progress...... thanks again for the help guys!
