Help Dead Battery!

[MapNerd]

Sounds like the transfer switch may be shot.

Please elaborate? And BTW thanks everyone for your efforts to assist!

I'm guessing but it seems to me that your coach is not directing shore power or gen power to the coach so your ATS in the cord reel may be bad or took a hit with a surge? Remember you can call Newmar 24/7 so you may want to try putting in a call to them. I did so on a Sunday and Erica picked up, guess she was on call, and conferenced me in to who I needed to talk to for the problem.

This one is hard to diagnose, as with all the suggestions it can be one of so many things. I texted @Chuggs to see if he's available to chime in.

Did you reset all 3 of these breakers?

So, I didn’t know that. I called, transferred to their after hours line and no one picked up. I got an automated voicemail box after about 15 rings.

I went ahead and ran a voltage test on my batteries. They are gone. Each one returning on average 6.4 volts.

These are 6v batteries...that is not your problem

Go back to the 300 amp fuse. I may have miss-stated the continuity meter method. Not sure if that actually checks a fuse or not. I think you might need to check both sides of the fuse to make sure it has power like someone else said. Maybe RedBaron can weigh in on that because he knows more about fuses than l will ever know.

I only have one of those three but just did. No dice

Not sure what happened. We stepped out for the day and came back to dead chassis batteries.

Don't mix up your chassis batteries with house batteries. I'm not sure what your tank level gauge shows you but mine shows house and chassis battery voltage. What does your show?

When your generator is running, does your EMS show 66 AMPS (or something in that area?)

On the Magnum control panel what happens when you press the CHARGE button? Can you turn that off then on?

Now do the same with Inverter

You can clear the faults in the Magnum panel by going to the Tech area, I can't remember if it gives you the option to press and hold for 5 seconds to clear faults but in that area is where you can clear them.

Is your coach the all electric, or do you have a gas range?

He's all electric, VTDP 43 footer

A multi meter has a continuity mode to beep if connection is made. This will test the fuse. You put a lead on each end and it will beep or show continuity if fuse is good .

Then there are 3 reset buttons..hard to see but they are there. This is the problem.

Remember these are installed upside down between the rails. Look at the picture, it will be up high closest to the ceiling of the bay in the corner. Very hard to access. The single button bear the lights is NOT the right one.

Sounds to me he came back and he hit LBCO. Why he wasn't charging is the question.

 

[MapNerd]

Chassis batteries are ODS in the rear.
House batteries on DS in the front.

I tested the voltage on the house batteries.
Also, I know it’s the house batteries because my chassis batteries are AGM and don’t take water. I knew it would change anything but made sure the matter idea wouldn’t take more water via the watering kit I installed a few months back.

Tank level gauge shows my batteries be good. Which makes sense per what @redbaron said. Attached a pic.

No the charge button does nothing. Just mocks me.

 

[redbaron]

I think he did charge, his batteries are 6.4 volts. That's 12.8v per pair.

I think he has a simple blown circuit.

This is correct. Newmar called back. No idea. Call us in the morning. Transfer switch sounds plausible.

With these breakers flipped, nothing that is on the inverter will work.

This means washer dryer and ac will work, as will the Oasis heater and stove.

Microwave and all outlets will not work.

**update** @nealc sent me a picture that @MapNerd sent him. His 2812 only had 1 breaker, and 2 studs.

We suspect the 300amp fuse

Just got off the phone with @MapNerd so we'll resume to the forum. Here are the pics he texted me.

Notice in the pic the green light is OFF? @MapNerd go back to the inverter and press the on/off button again after recycling the breaker as we did.
