Club Car MCOR Sensors & Conversion Kits

The MCOR (Motor Controller Output Regulator) is the throttle sensor on electric Club Car carts. It sits at the accelerator pedal and tells the controller how far the pedal is pressed. This page gathers the replacement sensors, the MCOR 4 conversion kits for older carts and the adapter harnesses that go with them.

Fitment and sizing. Three generations cover most carts. The original MCOR (OEM 102101101) fits the DS and Carryall from 2001 to 2011. MCOR 2 fits the Precedent from 2004 to 2011. MCOR 4 (OEM 105116301, also listed as 103850401) is the unit listed for 2012 and later Precedent, DS, Carryall, Tempo and Onward carts, and it replaces the older units through a conversion kit. The first two characters of the serial number give the model, the next two the year.

Frequently asked questions

Which MCOR does my Club Car need?

Identify the model and year from the serial plate, then match the OEM number in the listing. A 2004 to 2011 Precedent leaves the factory with MCOR 2; a 2012 or later cart with MCOR 4.

Why do sellers offer MCOR 4 conversion kits for older carts?

The earlier units are a known wear item, and MCOR 4 is the current design. A conversion kit adds the bracket or adapter harness needed to mount and plug it into the older pedal assembly.

What are the symptoms of a bad MCOR?

Hesitation, surging, a cart that will not move until the pedal is pumped, or one that keeps running after you lift off.
