The Centurion CS 2000 is a classic 20-amp power converter widely used in older recreational vehicles (RVs), pop-up campers, and travel trailers. Manufactured by Centurion 3000 (and later associated with Todd Engineering or Elixir), this unit handles a crucial job: it takes 120-volt Alternating Current (AC) shore power and converts it into 12-volt Direct Current (DC) power to run your RV's lights, fans, and water pump, while also maintaining your house battery.
Functions as the DC negative (-) return line to the battery's negative terminal or local chassis ground. 🛠️ Safety and Installation Best Practices centurion cs 2000 power converter manual wiring diagram
To wire a Centurion CS 2000 correctly is to perform a small ritual of electrical humility. You strip wires to the exact millimeter shown in the diagram’s margin. You torque the screws to the vague “snug but not stripped” spec. You zip-tie AC lines away from DC lines to prevent induced noise. You fuse the battery positive within 7 inches of the terminal—not because the diagram demands it, but because without that fuse, a short turns the battery into a welder and the converter into a firework.
: Absorption Mode (Constant 14.4V charge for nearly full batteries).
Are you troubleshooting a specific issue, such as or the battery not charging ?
Use a digital multimeter set to DC voltage. Touch the positive lead to a fuse terminal and the negative lead to the white ground wire. It should read between 13.2V DC and 13.8V DC . If it reads 0V, the internal transformer board has likely failed. Features a "CONVERTER - OFF - BATTERY" switch
A dead or dropped-cell battery (reading below 10.5V) will not have enough power to trip the internal converter relay or run the lights. Problem 3: The Converter is Humming Loudly
The culprit was a loose lug on the , where the 120V shore power entered the belly of the beast. It had vibrated loose somewhere between Barstow and nowhere.
All neutral wires are gathered and secured to the neutral bus bar (usually silver-colored). Green/Bare (Ground):
Always disconnect shore power and remove the battery terminals before attempting to touch any wiring. This link or copies made by others cannot be deleted
The CS 2000 serves as the electrical heart of the RV. It performs two primary roles: AC-to-DC Conversion:
Official wiring diagrams for the Centurion CS2000 are challenging to find, but thanks to dedicated RV community members, the essential connection details have been documented. The original factory manual suggests using . However, some field observations indicate the "charger wire" (the circuit that charges the battery) may be connected to Lug "E" or the lug with the yellow wire .
If you are restoring an older camper, troubleshooting a sudden loss of lights, or replacing a dead unit, understanding the wiring schematic and manual operational guidelines is critical. This comprehensive guide covers the specifications, wiring configurations, troubleshooting steps, and replacement options for the Centurion CS 2000. 1.

is a dual-system power center, meaning it handles both the incoming 120-volt AC power from a campground hookup (shore power) and converts it to 12-volt DC power to run lights, fans, and charge batteries.
