Ducati Energia 31.5µF Run Capacitor, P/N 416.15.27 | 9910303175, 425-500V~, 45x117 mm, for Single-Phase Alternators, Fits Mecc Alte Self-Excited Generators

Manufacturer Part Number: 416.15.27 (Ducati Energia, Series 416.15)

A generator capacitor is the voltage-regulation component in capacitor-regulated, self-exciting alternators. It stores and releases electrical energy to keep output voltage stable as the generator runs, working alongside the auxiliary winding to build and maintain the alternator's magnetic field. On smaller single-phase generator models, this is a cost-effective alternative to an electronic AVR.

This Ducati Energia 31.5 µF run capacitor (P/N 416.15.27) is manufactured to EN 60252-1/A1 with VDE approval and UKCA/CE marking, in a self-extinguishing plastic case (UL-94 Class V2). It measures 45 x 117 mm.

Common failure symptoms this part resolves:

• Generator runs but produces no electrical output
• Voltage far below normal (well under 120V/240V)
• Flickering lights or surging power
• Visible bulging, cracking, or resin/oil leakage from the capacitor case
