OP, You did post that you smelled burning...
Using a voltmeter check from frame ground to the pump power terminal and work backwards towards fuses etc. Does HWH have a diagnostic procedure?

I then hooked up all three batteries up and I go to start the coach and nothing????
I ended up firing up the generator to start the coach. I wasn't expecting that one.
I looked again to see that all terminals were hooked up correctly and fastened securely.
So now I have everything running and the slides still will not go out. The HWH panel board will not turn on???The light is on the dash telling me that they are down when there not.
Did I blow a fuse or a relay possibly? If so, where would I look?

You just did something you NEVER do. ALWAYS replace all batteries in a bank and not just the one that is bad. Doug

I would unhook all batteries in the unit so that there is no voltage make sure they are all charged, then hook all positive cables then all negative. Hooking up negative first can confuse the computers in the late model computers. We see it all the time in the auto shops.

Today I will disconnect all lines and reconnect positive first then negative. Then I will see what happens?
Thanks for your help. I will keep you posted.

Now I'm in trouble. The coach will not start. I turn the ignition key on and the dash doesn't even light up. No power.
I do have Aux power. Very confusing. I check my battery hook-ups and they seem like their hooked up properly.
I am baffled. I have a RV tech coming to my house to look at it on Wednesday evening.

As one of the previous posters said, you probaby have two "dead" batteries if you only replaced one of the three and/or you may have damaged your convertor. Good luck with the tech.

I had a motorhome and the bank of batteries were for the HOUSE part of the rig and there was a battery in engine compartment(gas) for the engine to start etc. So do you start your engine from your battery bank or maybe the battery for the engine is dead and not in the 3 battery bank. Just a thought.

Here's my update.....This as you know has been driving me crazy. I thought about it all yesterday and last night. So, the first thing I did today was bring my chassis batteries to the auto shop for a testing. They were both bad. What am I doing wrong?? I have a receptacle on the wall. I plug the RV in and walk away. I leave it that way for a period of time. Is it frying my batteries by being plugged in for that long period???Should I unplug it for a period of time and/or just keep starting the rig occasionally?
Also, I got HWH on the phone. I went to my control box and found that a couple of LED Red lights were not lit. A 5 amp fuse was blown near the Pump Relay. I tried replacing the fuse twice and it kept blowing.
I think it's the pump relay that's bad and that is why my slides don't work, airbag don't fill, and my hydraulic jacks are not working either.
I have a request for a tech to call me and walk me through this situation.
I don't wish it on anyone but as long as I can camp by the end of the month then I will be a happy dude! Jim

This is your first mention of chassis batteries and you may have independent problems. In most rigs the chassis batteries are NOT charged from shore power. So that part may be just dead chassis batteries.

It is unlikely your charger is frying the chassis batteries. Most chargers have a sensor and flip over to trickle charge upon reaching full charge, others simply shutdown. Did you have these batteries out of the vehicle like the house batteries all winter? Did you charge them before installing them? Are they holding a charge? Charge them disconnected or have them load tested.
I agree you seem to have several independent issues. All seem battery related, so how did you store the batteries? Could they have frozen? Were they off the concrete floor?
The smell you detected earlier could have been on the chassis side. I would wait for the tech to arrive before experimenting further.
