The Multiquip 59018 Excitation Capacitor 50Hz 35 mF is a genuine OEM component designed for MQ Towable Light Tower generators. Sourced directly from Multiquip, this capacitor is manufactured to the exact electrical specification required for stable 50Hz generator output on compatible light tower models. If your light tower is failing to build voltage or losing output under load, replacing the excitation capacitor with the correct 35 mF OEM part is a critical first step in restoring full generator performance.
Key Features
- Correct Capacitance Rating: — Rated at exactly 35 mF for 50Hz operation, ensuring the generator's alternator receives the precise reactive power needed to self-excite and build voltage to spec.
- Genuine OEM Component: — Manufactured to Multiquip's original electrical tolerances, so output voltage stability and generator response match the machine's original design intent.
- Direct-Fit Replacement: — Engineered as a drop-in replacement for MQ Towable Light Tower generators, connecting directly to the existing alternator excitation circuit without modification.
- Restores Generator Output: — A failed or degraded excitation capacitor causes the alternator to lose the ability to self-excite, resulting in no voltage output; replacing it immediately brings the generator back online.
- Electrical Safety Assurance: — Using the correctly rated OEM capacitor prevents overvoltage or undervoltage conditions that can damage connected lighting loads or the alternator windings themselves.
The excitation capacitor plays a central role in a brushless generator's ability to produce usable voltage. In a self-excited alternator, the capacitor supplies reactive current to the stator windings, allowing the alternator to build up voltage from residual magnetism without an external excitation source. When this capacitor degrades or fails — which can happen due to age, heat cycling, or electrical surges — the generator will spin freely but produce little or no output voltage. Replacing the excitation capacitor with the correct value, such as this Multiquip 59018 at 35 mF for 50Hz systems, is typically the fastest and most cost-effective repair to restore full generator function on a light tower.
