MOTO1988 Regulator Rectifier & Ignition Coil Kit for Honda Rancher/Foreman 1997-2006 — Relay & Spark Plug Included

Complete electrical tune-up kit including regulator rectifier, ignition coil, relay and spark plug engineered to fit Honda Rancher 350 and Foreman 400/450 models listed.

This MOTO1988 kit bundles four core electrical components you commonly replace together when troubleshooting charging, ignition, or starting issues on compatible Honda ATVs. Each kit contains a regulator rectifier, an ignition coil, a relay and a replacement spark plug packaged to the OEM reference 31600-HM7-003 (replacement for 31600-HN5-671). Before installing, confirm compatibility with your model year and OEM numbers to ensure a direct fit and reliable performance.

What exactly is included in this MOTO1988 ATV electrical kit?

The package contains one regulator rectifier, one ignition coil, one relay and one spark plug — the essential components for restoring charging and ignition systems. All parts are supplied together so you can address multiple failure points without sourcing items separately.

• Regulator rectifier (OEM 31600-HM7-003 reference)
• Ignition coil designed for listed Honda models
• Starter/ignition relay for consistent cranking
• High-quality replacement spark plug included

How do I know this kit fits my Honda Rancher or Foreman?

Compatibility covers Honda Rancher 350 TRX350FE/FM/TE/TM (2000–2006), Foreman 400 TRX400FW (1997–2003) and Foreman 450 TRX450ES/TRX450S (1998–2001). Verify your ATV year, model code and OEM part numbers against the listing (manufacturer part 31600-HM7-003; replacement 31600-HN5-671) for a confident match.

• Check your vehicle VIN/model plate and service manual
• Compare the OEM part numbers shown with your old parts
• Consult photos and contact support if you see differences

What problems can this kit help resolve on my ATV?

Replacing the regulator rectifier, coil, relay and spark plug often addresses dead batteries, poor charging, weak spark or intermittent starting. Installing fresh components narrows down electrical faults and restores reliable ignition and charging behavior when the battery, wiring and stator are in working order.

• Fixes undercharging or overcharging from a faulty rectifier
• Restores strong spark for consistent engine starts
• Eliminates relay-caused intermittent crank or no-crank conditions

How should I approach installation and post-install checks?

Basic mechanical skills and a few hand tools are usually enough for installation; follow your service manual torque and wiring diagrams. After fitting parts, verify charging voltage at the battery, confirm spark at the plug boot, and check for stable starter operation to ensure the repair succeeded.

• Disconnect battery before swapping electrical components
• Secure mounting bolts and reconnect wiring harnesses cleanly
• Measure battery voltage: ~13.5–14.8V with the engine running

Who this is for: This MOTO1988 kit is intended for DIY mechanics, professional ATV shops and owners of compatible Honda Rancher 350 and Foreman 400/450 machines who need a coordinated replacement set for charging and ignition troubleshooting. If you maintain older Honda ATVs and want a single purchase to replace multiple suspect electrical parts, this kit provides a practical, OEM-referenced option. For any uncertainty, compare model years and OEM numbers or contact seller support for guidance; MOTO1988 offers 24-hour customer service and a one-year product support period.
