The Multiquip 31630ZDX802 is a genuine OEM Charge Coil Assembly (26A) MD105 designed for the MD105 series mid-sized hydrostatic ride-on power trowel. Sourced directly from Multiquip, this coil assembly matches the original electrical specifications of the machine's charging circuit — no guesswork on output rating or connector fitment. If your MD105 is showing signs of a weak or failed charging system, replacing the charge coil with the correct OEM unit restores proper electrical operation and protects downstream components.
Key Features
- Correct 26A Output Rating — Matched to the MD105 charging circuit's specified amperage, ensuring the electrical system receives the output it was engineered around.
- Genuine OEM Construction — Wound and insulated to Multiquip's original production standard, so coil resistance and output curve align with what the engine's ignition and charging system expect.
- Direct-Fit for MD105 Trowels — Engineered to mount to the MD105 stator plate with the correct bolt pattern and lead wire routing — installs in place of the original without modification.
- Restores Charging System Integrity — A failing charge coil causes battery drain, erratic instrument behavior, and eventual loss of electrical power mid-operation; replacing it returns the machine to full electrical capacity.
- Verified Multiquip Part — Part number 31630ZDX802 is the authoritative Multiquip OEM reference for this assembly on MD105 equipment, eliminating cross-reference uncertainty at point of purchase.
The charge coil is a critical component within the engine's magneto or stator assembly. As the engine runs, the coil generates alternating current by rotating through a magnetic field — this current charges the battery and powers the machine's electrical system. When the charge coil degrades or fails, the battery can no longer maintain a charge under load, leading to shortened run times, warning light activation, and eventual electrical shutdown of the trowel. Replacing a worn coil promptly keeps the MD105's onboard electrical system functioning as designed and prevents unnecessary strain on the battery and regulator/rectifier.
