No power to rv

[fastwhls]

Well, I just replaced my two rv house batteries since the old ones died on me. Now problem I'm having is I don't get any power to rv. Only way I can get power is either hook to shore outlet or run my generator, when I stop the generator or unplug from shore I loose all power to rv even with new house batteries. My refrigerator works on LP gas and electricity. When I unplug from shore or turn the gen off it will not kick to LP...[emoji20] [emoji20]
Anyone has any suggestion...??

You missed or crossed up a wire.

Send some pictures of your connections.

If you had any sparks while handling the cables look down along the + cable for a fuse or circuit breaker.

Make sure your battery disconnect switch is on.

Battery discount switch is on. Power from house batteries power the generator starter but nothing comes to rv...
This is the wiring for two new ones

[twinboat]

Check under that ball of electrical tape in the top center. That's a positive feed to something and could be a bad connection hidding under there.

Next, follow the lower left cable with the NEW looking yellow end. See if that goes to chassis ground or an inverter negetive connection.

Also look around for wires not connected or a breaker somewhere.

Looking at your picture I see three wires connected to the negative post, but only 2 wires connected to the positive post. Could one of the wires have dropped down and was inadvertently missed when making the connections?

This is a picture of the wiring with old batteries before I do anything. Unfortunately being on wheelchair makes it difficult to get around and trace the cable but I try.. thank you so much for your help...

Sent you a PM with pictures. When I last changed out all of my 12v batteries, I broke off a ground cable moving the batteries around. The grounding board and manual disconnect switch (on my 2005 anyway) is to the right of the first battery (left battery in your picture) and attached to the motorhome frame rail. Kind of hidden until I took all the batteries out and looked around. In moving the cables around to finesse the batteries into place, I must have put too much pressure on the negative / ground cable for the batteries that runs back to this board and it broke off. In my case, I discovered no 12v power to the engine because it wouldn't start. I'm not sure if it took out my coach 12v power too as I never checked it, panicking on why my motorhome wouldn't start, and focusing on that.

Here is my battery wiring set-up, with my coach and chassis (engine) batteries set in place with the grounds on the top side-RT

Hi, I did get your pictures. Thank you so much. I was told to check see if all my connections are not damaged. I had it done by mobile battery service.. but I will check it tomorrow. Stuck in RV park.. can't leave till get it fixed.
Thanks again.

Can you get the mobile rv guy to come back out? Seems like he should have some responsibility to assure the new batteries are installed correctly and the circuits are working.... as in good charge voltage when plugged in and supplying power when running off the batteries. I would expect a reputable mobile rv tech to find a simple problem here and take care of this no charge.

Good luck,
Bill

I can't tell with complete certainty, but it almost looks like you have four wires connected to the side-wall post in your old battery picture but it looks like five wires after the new battery install... or is it just how the wires are positioned from one photo to the other? (I only have four connected at that side-wall post.) -RT

I was watching him while he was changing the batteries. He didn't touch that connection. Only things he touched were batteries tie downs and the batteries leads connection...

So are there four or five cables connected to that post in each picture of the old batteries and new batteries? Cables do appear to have been moved around and I'm curious how many cables are connected. The picture that looks like there are five could be a cable that is just running past that post or the camera angle. Guess I'm looking for the cable with the pink tape in the 'old' battery picture that I can see in the new batteries picture.

Also, it might come down to pulling out the batteries and and inspecting the grounding board mounted to the frame rail. That's where one of my grounds broke off and I lost 12v power. -RT

I agree twinboat, I don't like the looks of that bunch of electrical tape wrapped around that positive cable, top center of the photo. Looks like someone tried to tape up a damaged section of the cable or something. Not good, it shouldn't be there regardless if it's the problem or not.

RT, you are right now that I look at it, I don't see the cable with pink tip in the two pic before changing them.... Have no clue where he got it from...

Well the mystery got solved... Problem was a loose ground which kept triggering the breaker.

Just want to THANK ALL YOU GUYS for all your help and suggestions...
RT, Duner, twinboat and rest who gave me their input... You guys are the best..!!
Thank you Thank you..[emoji4] [emoji4]

You do know there is a master 50 amp fuse for the house battery system if that's tripped you have no 12v juice for the RV

Check to make sure your inverter is plugged in. My power plug got knocked out of the elec. outlet and I had similar issues.

Hi Steve, yes I do know, had a loose ground which was triggering the fuse....

Thank you so much...
