Sent my order

Hi, 

I had AGM (4X6 Volts, Total 800AH, 400 usable) batteries in my Dynasty 2009 and although I was able to spent the night with some spare power to start the Gen in the morning, it was a stretch. We have two Cpap running continuously and the AC fridge and a lot of other power eaters. 

I decided to go LFP and ordered 5X170AH (850AH usable power) Renogy batteries who appeared to be good quality at a good price. Also, I had to upgrade the Board in my Magnum 2800 Inverter/charger and change my Magnum ME-RC remote to provide a LFP profile. Also, I removed the BigBird relay and installed a DC/DC charger to provide charging with Solar and/or Alternator. 

I thought I was home free BUT I forgot one thing. While dry camping I happened to get the coffee maker, the blender and the toaster on which got the Inverter breaker to pop. After, resetting it I found that the batteries where less and less capable and would not charge properly. 

Let's move 6 months later and ALL my batteries where dead. Won't charge at all (They stay at around 3 Volts). I called Renogy who gave me a lot of things to try but nothing would work. Thanks Renogy, they honoured their warranty and sent me 5 replacement batteries. 

Unless, somebody can explain me differently, I think the BMS's in the batteries being 100AMPS failed and brought the rest of them down. 

Now, I found 2X480A/H Vicmax Battereis on Internet that comes with a 250AMPs BMS. I installed them and wasn't expecting much BUT they work great. Even with the toaster and Microwave on they stay up and provide ample power for a couple of days without running the Gen. 

I have 5 brand new Renogy batteries for sale...

That's the coach version. They estimate a range of 225 miles with a 520kWhr battery system. Gives a rough idea of range/battery capacity for something that size. 

Wow, it would take a couple of months to do the Florida-Montreal trip... especially towing a trailer!

Here is a link to the 09 wiring diagrams in our files.  Click on the title to get the option to download all in one single PDF file.

Hi Frank, 

thanks very much for the file. It's the missing link I was waiting for my understanding of the different system in the coach. It will be very helpful. 

Thanks again.

I've also talked with Brett and he sent me the wiring diagrams he has.

Hi Kevin, 

you mention you were able to get the wiring diagram for an 09 Dynasty?

Would it be possible to get a copy since the one I have is for an 08? 

Tks

Kevin,  as a 2009 Kongsberg Coach owner with a few issues, I look forward to learning more about the possibilities with the Parker system. 
Please keep us posted.  
 

Same with me.

Any ways we can keep those great coaches alive will be welcome...

Canned answer by Valid when their keypad fails! Myself and many others have heard it!

Mine can't be turned on without ignition key on anymore, otherwise it's still functional (for now).

I pulled it out for inspection. No signs of ever having water intrusion!

Hi Ben, 

i didn't want to imply that it was your case. I mentioned that on mine it was the problems. I removed the plastic over the button and it was all corroded. 

Have e great day 

When I bough the Dynasty, I couldn't go in travel mode. After talking to Valid, they said it was most probably a bad keypad. 

I changed it and everything as been fine for the last 5 years.  

They mentioned that it is common to have water coming from the driver window sneaking under the pad and corroding it. 

Good luck 

Thanks guys for the fast replies. ,

It looks that I have to find a deep enough lake to put the coach in it or hope for the best and not have problems...

Sad day!!!

Hi, 

I have an 09 Dynasty and I see a lot of Intellitec boards in a closet in the back of the coach. I didn't find anywhere a Boar mentioning Kongsburg... 

Also I have the build sheet that says MegaTech CCM front and back. Does that mean I can be sure I don't have the plague??? 

Thanks

P.s. I don't want to steel the tread
