Multiquip 8101350013 Field Assembly Exciter

The Multiquip 8101350013 is a genuine OEM Field Assembly Exciter designed for DCA and NGA series ultra-silent and super-silent diesel generators, including DCA70, DCA85, DCA100, DCA125, and DCA150 series units. As a factory-original component, this part is manufactured to the same specifications as the unit installed at the factory, ensuring a direct, confirmed-fit replacement for a wide range of Multiquip generator models. Compatible units include the DCA125SSIU, DCA125SSJU, DCA150SSJU, DCA150SSVU, DCA70SSIU, DCA70SSJU, DCA85SSJU, DCA100SSVU, and NGA150SSPUPL, among others. Sourcing the correct exciter assembly is critical — an incorrect or worn part will directly affect voltage output stability and overall generator performance.

Key Features

• Genuine OEM Winding Specification — Factory-wound field coil assembly matched to the alternator's original excitation output requirements, preserving correct voltage regulation across load ranges.
• Direct-Fit Alternator Replacement — Engineered to seat and connect exactly as the original component within the DCA and NGA series alternator housings, with no modification to mounting or wiring needed.
• Broad DCA and NGA Series Coverage — Confirmed fitment across DCA70, DCA85, DCA100, DCA125, and DCA150 series generators, as well as NGA100 and NGA150 super-silent natural gas alternator units.
• Stable Power Output — A correctly functioning exciter field assembly maintains consistent magnetic flux within the alternator, which is essential for steady voltage delivery to sensitive site equipment and tools.
• Electrical Safety Integrity — In generator applications, a degraded or failed field assembly can cause voltage spikes, under-excitation, or complete loss of output — replacing with a genuine OEM part restores safe, controlled electrical generation.

The field assembly exciter is the stationary winding component inside the generator's alternator that creates the initial magnetic field used to excite the main rotor. By supplying this controlled electromagnetic field, it enables the alternator to self-regulate voltage output and respond accurately to changing electrical loads. When the exciter field assembly degrades — through insulation breakdown, winding damage, or heat fatigue — the generator may produce erratic voltage, fail to build power under load, or lose output entirely, making prompt replacement essential to restoring full generator function.
