Product Overview

A tractor that cranks normally but has weak yellow spark, becomes hard to restart when hot, or loses spark after running may have a failing coil. Those symptoms can also come from points, condenser, cap, rotor, wiring, or incorrect coil voltage, so the coil should be tested before it is blamed.

The coil raises battery voltage high enough for the distributor to fire the spark plugs. Its internal resistance is intended for the matching 12-volt ignition layout; it is not a universal answer for every 6-volt tractor or every 12-volt conversion.

Confirm a distributor-equipped gasoline engine, 12-volt system, coil polarity, primary resistance, mounting diameter, and 353875R91. Determine whether an external ballast resistor is already in the circuit before installation.

Key Features & Performance

  • Internal resistance for matching 12-volt distributor systems
  • Canister-style replacement for the listed tractor families
  • Restores strong secondary ignition output when the original coil has failed
  • Useful for heat-related or intermittent coil faults confirmed by testing

Replaces Part Numbers

  • 353875R91

Common Uses

  • Repairing a tractor with confirmed weak or missing spark
  • Replacing a coil that opens internally after warming up
  • Completing a correctly wired 12-volt ignition conversion

Technical Specifications

  • Product Type: Canister ignition coil
  • Electrical System: 12 V; internally resisted design
  • Ignition Type: Distributor and breaker-point system
  • Condition: New aftermarket replacement

Installation & Fitment

  • Disconnect the battery and label every coil wire
  • Measure supply voltage and verify whether a ballast resistor is used
  • Mount the coil securely away from excess heat
  • Connect positive and negative terminals for the tractor polarity
  • Set points and timing, then verify a strong spark before operation

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above. Model year, production date, serial number, engine or equipment specification, installed options, and previous repairs can change fitment. Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.

Frequently Asked Questions

Q: Will this fix a tractor that cranks but will not start? A: Only if the existing coil is the cause. Fuel delivery, points, condenser, distributor parts, wiring, compression, and timing can produce the same symptom.

Q: Can I install it on an original 6-volt tractor? A: No. The electrical system and ignition circuit must be configured for the coil voltage and resistance.

Q: Why does the tractor quit after it warms up? A: A coil can fail hot, but a condenser, connection, charging fault, or fuel restriction can do the same. Test for spark at the time of failure.

Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
