Hey Ron
You sure are correct that there is not much room to charge the engine battery. I can reach the positive terminal without much problem but the negative is a dog. Now I connect the negative to the vehicle body at any not painted place and it charges just fine.

Ron got it on the charger this morning...chassis battery still dead...
...the box near the battery does not push out the yellow reset flag when he tries to start rv. There is no click .. it is like there is no battery in the unit !
We unplugged the shore power...and found that our house batteries are dead too...We have been on shore power for a week..the flag on the box near the house batteries has had the reset flag, both in and out .. not sure where it should be at this point.
On our previous Dorado, we knew if the slide was not in all the way, the motor would not start...so we put the slide out and back in...made no difference.
He took a look at the fuse box under the drivers side, but was not sure what to look for...now is checking paperwork on that.
This RV was running perfect a week ago.

Ron will appreciate any feedback..while he reads all the pages regarding the electrical system and battery setup.

Thanks !

Question, and this is not intended to insult anyone's intelligence; did you check to make sure the breaker for your shore power did not trip?

With my prior coach after one of our trips I plugged the coach in to the outlet and then go side tracked and forgot to turn on the breaker. Lesson learned relatively quick.

vkb · 03-10-2016, 09:29 PM

thanks .. any suggestions are welcome !

If you are referring to the box next to the house batteries...as the Shore Power Breaker...the yellow reset flag is depressed...not showing...
if there is another Shore Power breaker, we are not aware of..please tell us
more !!
The USE button has been checked.
The box next to the battery has been checked.--flag not extended.

This 'animal' is completely different from our previous motorhomes !

The levers in the battery disconnect switches (red in the coach battery box and yellow in the chassis battery area) should be in - you should not be able to see them. Pushing the red button should put them in the out position and disconnects the batteries. If they are out, the batteries will not charge on shore power. However, if they were disconnected I am surprised that all your batteries are dead. I would try disconnecting your coach batteries and see if shore power will charge your chassis battery alone.

I think he probably meant the breaker in the 30 amp box. Are you sure you are getting 30 amp power to the coach.

Oneilkeys · 03-10-2016, 09:40 PM

Have you actually measured the voltage in the batteries? When you say you "put in on the charger", do you have a separate charger hooked up to the chassis battery and the battery was not taking a charge?

vkb · 03-10-2016, 09:46 PM

Thank you MEN ! I am passing along all of these thoughts to Ron ..
The one thing we HAD NOT checked was the breaker for the outlet we are using from our home outlet !

Sorry

Stepped out with the dog to take our 2 mile walk around the park.

I was referring to the breaker which controls the house outlet supplying power to the coach. Sometimes we overlook the obvious and that is the snake that will bite us in the butt.

vkb · 03-10-2016, 10:40 PM

thank you Dave .. all breakers are on ..
we are in our driveway at home...breaker box good, nothing tripped...
we have power to the 'house' batteries now, as the box next to the 2 house batteries was tripped...
however, the chassis battery is not responding. Ron had it on a charger all morning ...
The box next to the chassis battery is not tripped.
Get this...we all know that it must be in park to start..a given..
put your foot on brake and try to move the shifter .. (to make sure it was completely in park) will not budge ..
In another feed, someone had mentioned the cable to the shift lever having a problem...does anyone recall this situation?
this seems unusual..unless this is significant to this RV .

If you are ugged in at your garage or an outside connection be sure you didn't trip a GFCI. When you were on shore power was the Use/Store switch in the Use position. The house battery will not charge if the switch was in Store. When you first put the switch in USE did you here a relay click in the front of the coach. The Use/Store switch will not operate now if the house battery is dead. Are any of the flags showing on the circuit breaker next to the house battery or the one near the chassis battery? Neither flag should be visible.

bevedfelker · 03-10-2016, 11:00 PM

You never responded to Oneilkeys question about whether you had the chassis battery hookrdvupvto a battery charger and still got no charge on the battery. If this is the case. it sure sounds like a bad battery to me.

bevedfelker · 03-10-2016, 11:02 PM

And if your chassis battery was dead and you had the ignition switch on, you would not have been able to move the gear lever because it has an electrical lock on it.

vkb · 03-10-2016, 11:46 PM

Ed & ONeil .. thank you, again, for your replies...
1) We definately have shore power to the motorhome
2) To our knowledge, we have NEVER heard a click when pushing the USE button...which we have pushed a number of times !
....NOW...through all of the forum q & a ... I am now concerned that the relay
box next to the house batteries (under the steps)..has had the yellow flag appearing all this time...so, Ed, you are saying that, even tho we had elec. to all of our lights, etc. as we were plugged into shore power,...we WERE NOT, charging our house batteries because that box was tripped ?!
We NOW have made sure that both the flag at the house & chassis battery are depressed.
3) When attempting to move the gear shift lever, the ignition was not turned on.
We do realize there is a lock on that mechanism.

So, as we stand now, if we have read your notes correctly, Ed, we are... connected to our shore power...both boxes do not have flags appearing...
and Rons battery charger showed the battery took a full charge.

However, the motorhome did not start or even act like it wanted to !

Question...once we have the house batteries fully charged...will the motorhome start using the emergency start on the dashboard ?

thanks again
Kay & Ron

Oneilkeys · 03-10-2016, 11:53 PM

To answer your last question first, yes, the house batteries should start the coach with the emergency start switch pushed, if your only problem is a dead chassis battery. If the chassis battery is at full charge, using the emergency start switch will do no good. Which battery took a full charge? The chassis battery or the house or both?

Oneilkeys · 03-10-2016, 11:54 PM

If the box was tripped, you were not charging your batteries. Some inside lights will still work.

Oneilkeys · 03-10-2016, 11:57 PM

If you have a fully charged chassis battery and the hi bus box is not tripped, then you have a problem somewhere else. It may be an ignition relay problem or an engine fuse problem. Did you download the battery troubleshooting guide? It tells you how to check the ignition relay.

vkb · 03-11-2016, 12:10 AM

ONeil...the battery charger was on the Chassis Battery.. and showed it fully charged when Ron removed it. .. the box near that battery is NOT tripped

We do not know how long the house battery box had been tripped..that box has been reset
We presume, now that this box is reset, .. our house batteries will charge.

WE, NOW, DO NOT HAVE ANY FLAGS SHOWING

If we have a bad Chassis Battery,...has anyone gotten into the battery, per the instructions in the Thor Manual...remove the work station, etc in the right dashboard ?

thankyou again ! K & Ron

JamieGeek · 03-11-2016, 12:29 AM

If I'm reading your status correctly: The chassis battery is fully charged but the coach won't start.

When you turn the key to accessory (not start) does the dash light up? Can you turn on the headlights? Do you have a voltmeter? If so have you tried taking a direct measurement off the battery posts (I realize that is a bit of a chore with the chassis battery being buried under there)?

If the headlights and/or dash don't light up (or you measure 12+ V) I'd suspect the hi bus box either being tripped or bad.

Same thing on the house side: Unplug the 120V power, switch to Use, and see if any of the interior lights turn on (or measure the house battery voltage).

Another thing: Take a close look at your house batter(y/ies) if they are Harris then they are most likely shot.

Oneilkeys · 03-11-2016, 12:33 AM

If your chassis battery is fully charged and showing 12.6 to 12.8v it is not bad. You need a volt meter to find that out. If you have a fully charged chassis battery, your problem is somewhere else, maybe in the ignition relay or possibly the electrical power is not making it to the starter. It could be a fuse or loose wire. If you turn the ignition to on and the chassis battery flag does not show then you may have a blown fuse. However fuses blow for a reason.
