Multiquip B3137000803 Exciter Field Assembly - OEM Generator Replacement Part

The exciter field assembly is a critical component of the generator's open-delta excitation system, providing the electrical field necessary to generate AC power output. This assembly works within the electrically independent winding system wound among the stationary windings of the AC output section, supplying power from the voltage regulator through the parallel connections during steady state loads.

This genuine OEM exciter field assembly is engineered specifically for Multiquip's EPA Tier 4 Final certified generator line. The open-delta excitation system consists of four connections (A, B, C, and D) that work in coordination with the automatic voltage regulator, rectifier, and main generator field winding to maintain stable power output. When the exciter field assembly fails, symptoms may include voltage regulation issues, unstable power output, or complete loss of AC generation despite the engine running normally.
