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.

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
