The Centurion CS 2000, commonly found in vintage RVs, is a 20-amp power converter and battery charger that requires ventilated installation and specific wiring: AC black (hot) to source, AC white (neutral) to source, green to ground, DC red to battery positive, and DC white to battery negative. Due to its age, users often report that the charging module is inefficient and may require replacement with a modern unit.

The Centurion CS 2000 is a legacy power converter frequently found in older recreational vehicles (RVs) and pop-up campers. Its primary function is to manage the distribution of AC shore power and convert that AC power into 12V DC power to operate cabin lights, water pumps, and minor appliances.
Understanding its operational parameters and terminal layout is essential for safe maintenance or a modern replacement project. ⚡ Technical Overview & Common Applications Centurion CS 2000
typically acts as a 20-amp power converter. In standard RV applications, it handles two distinct electrical grids:
120V AC Input/Output: Feeds from an external shore power cord or generator to typical household wall outlets and continuous-draw appliances (like air conditioners or microwaves).
12V DC Output: Supplies power for low-voltage systems like incandescent or LED ceiling lights, roof vents, water pumps, and stereos.
💡 Key Limitation Note: The integrated battery charging module in the
functions strictly as a basic "trickle" charger. It is widely recommended in RV communities to bypass this module and use a dedicated smart charger if you are running modern deep-cycle or lithium batteries. 🔌 Standard Wiring & Terminal Configuration
While small differences exist across production years, a basic understanding of standard RV color-coding establishes the typical layout for this unit: 1. 120V AC Input Side
The incoming high-voltage wiring typically follows standard North American household conventions:
Black Wire: Connects to the AC source "Hot" (shore power or generator source). White Wire: Connects to the AC source "Neutral".
Green Wire: Serves as the "Ground" and must be securely bonded to the metal chassis of the RV. 2. 12V DC Output Side
Low-voltage DC wires generally distribute energy to the lighting and accessories. Note: In standard automotive and RV DC systems, wire color schemes differ significantly from AC schemes.
Red Wire (or sometimes Blue): Carries the positive (+) DC load output directly to standard 12V appliances and to the positive terminal of the house battery.
White Wire: Functions as the DC negative (-) return line to the battery's negative terminal or local chassis ground. 🛠️ Safety and Installation Best Practices
Working with electricity in a mobile environment introduces severe risk hazards. Always adhere to these structural rules: centurion cs 2000 power converter manual wiring diagram
De-energise completely: Before modifying any wiring or removing terminal covers, ensure the RV is entirely disconnected from shore power, generators are off, and battery cables are safely uncoupled.
Ventilation is critical: Locate or remount the power converter with ample, unobstructed space surrounding its cooling fan to prevent critical thermal overload.
Verification step: Always perform active measurements with a digital multimeter to check for exact polarity and voltage at both AC and DC terminals prior to permanently sealing wire nuts or crimps. 🔄 Modern Upgrades and Replacements
Due to its basic charging technology and age, many owners choose to replace the Centurion CS 2000
rather than repair it. If you are looking to swap out an aging unit:
Drop-in replacements: Companies like Progressive Dynamics and WFCO manufacture modern power converter conversion kits designed to fit directly into the physical dimensions of legacy cutout slots.
Multistage charging: Modern replacements feature intelligent 3-stage or 4-stage battery charging profiles. This prevents battery boiling (overcharging) and keeps your RV's 12V reserve highly efficient. Centurion Cs 2000 Power Converter Manualgolkes
The hum of the 1994 Fleetwood Bounder was the only soundtrack to Elias’s evening until the lights flickered and died. In the sudden, heavy silence of the Mojave, the smell of ozone wafted from beneath the dinette seat.
"Not now," Elias muttered, clicking a plastic flashlight to life. He unscrewed the brown plastic faceplate of the Centurion CS 2000. It looked less like a modern power converter and more like a relic of a Cold War bunker—a dense snarl of copper, dust, and faded plastic.
He pulled a sweat-stained, photocopied manual from the glovebox. Page twelve was the "Holy Grail": the wiring diagram. To anyone else, it was a chaotic web of lines, but to Elias, it was a map home.
His light traced the path. The White wire—the common ground—was bolted to the metal chassis, thick and unyielding. The Red wire, the lifeline carrying 12V DC power to the battery, looked frayed, its insulation cooked brittle by decades of desert heat. Then there were the Blue and Yellow circuits, the veins that fed the water pump and the overhead bulbs.
The culprit was a loose lug on the Main Lug (Black), where the 120V shore power entered the belly of the beast. It had vibrated loose somewhere between Barstow and nowhere.
With a rhythmic rat-tat-tat of his screwdriver, Elias reseated the wire, tightening it until his knuckles turned white. He checked the diagram one last time: Blue to fuse one, Yellow to fuse two, White to the bus bar. He flipped the breaker.
The cooling fan inside the Centurion let out a low, mechanical purr. A moment later, the overhead lights bloomed into a warm, amber glow. The desert was still dark, but inside the Bounder, the map was clear again.
A very specific request!
The Centurion CS 2000 is a power converter designed for use in RVs, boats, and other off-grid applications. While I couldn't find an official manual or wiring diagram from the manufacturer, I was able to gather some information that might be helpful. Please note that this is not an official document, and you should consult the manufacturer's documentation or a professional if you're unsure about any aspect of the installation or wiring.

Important Safety Notes
The Centurion CS 2000 is a 20-amp switching power converter commonly found in older RVs like Jayco or Aliner models. It is designed to convert AC shore power into 12V DC power for your lights and appliances while providing a trickle charge to the house battery. Wiring Overview
While finding an original physical manual is difficult as the company is no longer in business, the wiring follows standard RV electrical conventions: AC Input (120V Shore Power) The Centurion CS 2000, commonly found in vintage
Black Wire: Connects to the AC "Hot" line from your shore power or generator source. White Wire: Connects to the AC "Neutral" source.
Green Wire: Connects to a metal chassis ground point on the RV. DC Output (12V RV Systems & Battery)
Red Wire: DC positive (+) output. This connects to the positive terminal of your RV battery and the 12V fuse panel.
White Wire: DC negative (-) or ground. In many Centurion units, the white wire serves as the common negative for the 12V system. Installation & Maintenance Tips
Mounting: Place the unit in a well-ventilated area near the battery, away from direct heat or moisture. Ensure enough space for the cooling fan to operate.
Safety: Always disconnect shore power and the battery before working on the unit.
Testing: Use a multimeter to verify correct polarity and voltage at both input and output terminals before finalizing connections.
Replacement: Many owners replace the aging CS 2000 with modern 3-stage chargers (like Progressive Dynamics or Ctek) because the original "trickle charge" module is often insufficient for modern deep-cycle batteries.

I cannot directly provide the full copyrighted manual or a specific wiring diagram image for the Centurion CS 2000 Power Converter. However, I can give you the key wiring features, typical connections, and how to find the official diagram from the manufacturer (Progressive Dynamics, who now owns the Centurion brand).
The Centurion CS 2000 is an older ferroresonant style transformer. If you are digging into the wiring because the unit hums loudly, runs hot, or outputs 10V or 18V...
Don't just rewire it. Replace it.
Modern Progressive Dynamics 9200 series units are a drop-in fit for the CS 2000 hole. They are quieter, smarter, and the wiring is color-coded like modern Romex (Black, White, Green, Red). Replacing the unit is safer than trying to rebuild a 20-year-old PCB.
Disclaimer: This post is for informational purposes. Wiring 120V and 12V systems involves risk of fire and electrocution. Always disconnect shore power AND the battery bank before touching wires. If you see melted insulation or smell burning plastic, call a certified RV technician.
