Replacing the converter

Hello. This was prob. posted here before but I couldn't find anything. I am going to change out the converter in my 2000 TT. It is the Centurion cs 3500. It works but just cooks the battery and runs all the time. Being in the bedroom, it drives my wife and I crazy. I am looking at the Inteli-power series 4600. They make a 35 watt unit. Has anyone done this conversion before and if so, what do I have to watch out for, etc.
Also, if not this particular unit, does anyone have an alternate suggestion? Thanks to all. Jeff

HI Jeff,
I just replaced my Centurion 3500 in my T-2570 with a WFCO. It was pretty easy job, needless to say make sure all your power is disconnected including the battery. What I did was label the wires as i disconnected them. The only problem I ran into was having to reroute the ground wire around the back of the new converter, so I just attached a new ground wire to the old one to extend it. every thing fit like a glove, I did not even have to modify the hole in the cabinet where the converter goes, it was the same dimension. Good luck let me know if you have any more questions Ken

Hi Jeff

I can vogue for the Intellipower convertors. They are great units and include a desulfate mode.

I do not see that it is an exact drop in on the 4600 series 4600 series Upgrade Kits

The Intelli-Power 4600 Series Upgrade or Replacement RV Converter/Charger with built-in Charge Wizard is the Brand of choice by leading RV manufacturers.

But they are good units. On my American CS6000, They bought out Centurion, when the fans went out I put a Intellipower PD 9260C in place of it. However that is a chassis unit I had to mount it remotely. My layout allowed this to happen without any issues. The 4600 "may" still work it just may take some maneuvering to get it in.

Best Convertor is also talking about the WFCO upgrade for the CS3000 Centurion CS3000 Replacement

The WFCO is a good converter as well. This may be closer to a drop in. It has 3 stage charging, temperature controlled fans. Power CentersWFCO WF-8735P, WF-8735 35 Amp Power Center it does not show to have the desulfate mode. You can add a Battery Minder Plus which has desulfate mode in it for around $40 to maintain your battery when your not out camping.

And there is also a replacement board direct from American Enterprises. AMERICAN ENTERPRISES, INC. | RV Replacement Boards

They are suppose to be 3 stage charging as well but no desulfate. Like with the WFCO you can get the Battery Minder Plus to do that. American sure is lacking on much tech info on their website. On the older web site they use to have more info.

When hooking any of them up, like Ken said mark the wires before you take them off. And take good clear pics too. They help us remember better..... One heads up on the white wires. Sunline used white for 12 Volt DC common in stranded wire for wire running in the camper and they used white solid wire for 120 VAC common. That is not to say someone else may have added a white stranded AC common wire or the old converter itself had stranded white AC on it for something so do not think all stranded whites are DC common.

Point: Make sure you do not mix up the AC common with the DC common just because the colors are the same. Tying DC common to AC common will cause issues with the ground fault receptacles. Again the need to mark each wire as you take it off assuming it is correct to start with.

Good luck and hope this helps

John

Jeff I installed the (WFCO 8935 ANP 35 Amp) And as John mentioned take good pictures I had a friend take pictures for me and it helped. Even though the lay out is completely different it helps to double check that the wires have the correct size fuse.

Thanks Ken and John. Will do as far as the pics go. I will decide which unit and post some pics for someone in the future. BTW, I just tore the front wall of our bedroom out from water damage. I am a carpenter/builder by trade so it was not a bog deal but I did learn that apparently, the sunlines are built inside out. There were screws that could only be put in from the outside without siding. Anyway thanks, Jeff

Soory to hear about the water damage part. Bummer. Having dealt with some of that myself it can be shank your head at times until you figure out how they built the units. If you can, take pics of the process and post. The pics really help folks going through this in the future. We all learn form each other.

Good luck

John
