The Wacker Neuson Electrolytic Capacitor 1000/63V is a genuine OEM component designed for the GP3800A, GP5600A, GPS5600A, GP6600A, and GPS6600A portable generator series. Sourced directly from Wacker Neuson, this part meets the exact electrical specifications required by these generators, ensuring the capacitor performs as the original did from the factory floor. It covers a wide range of configurations across these families, including standard, wheel kit, electric start, EPA, CSA, and CARB-compliant variants. When you need a direct, verified replacement for part number, this is the correct part for the job.
Key Features
- Correct Voltage and Capacitance Rating — Rated at 1000µF/63V to match the original electrical specification, ensuring stable charge storage and proper circuit behavior in your generator's control system.
- Genuine OEM Part — Supplied by Wacker Neuson, this capacitor is manufactured to the same standard as the component installed at the production line, not a generic substitute.
- Drop-In Replacement — Engineered to fit the original mounting position and terminal configuration, so installation is straightforward with no adapting or reworking of existing connections.
- Broad Generator Family Coverage — A single part number covers GP3800A, GP5600A, GPS5600A, GP6600A, and GPS6600A models across EPA, CSA, CARB, standard, and wheel kit variants — verify your model number before ordering.
- Protects Generator Output Stability — A functioning capacitor smooths electrical fluctuations in the generator's circuit. A failed or degraded capacitor can cause erratic output, starting issues, or damage to connected electronics.
- Electrical Safety Compliance — Using the correct rated capacitor matters in generator applications — an under-spec or mismatched component can create voltage irregularities that pose a risk to both the machine and connected equipment.
An electrolytic capacitor stores and releases electrical energy within a circuit, acting as a buffer that smooths voltage fluctuations and supports stable operation of electronic controls. In a portable generator, the capacitor plays a key role in the excitation and regulation circuitry that governs power output quality. When a capacitor fails — through age, heat exposure, or overload — the generator may produce unstable voltage, fail to start, or deliver power that can damage sensitive tools and equipment plugged into it.
