Product Overview
A tiny diode can create a surprisingly confusing complaint: backfeeding between circuits, a relay that will not release, a fuse that opens, or an interlock signal that travels the wrong direction. Test the diode in both directions and inspect the circuit for a short before installing another one.
The diode allows current in one direction while blocking reverse flow in the tractor’s control wiring. Orientation is critical; match the LVU804171 marking, connector or terminal form, polarity indication, 1.5-amp rating, and circuit location from the wiring diagram.
Key Features & Performance
- One-way circuit protection for matching John Deere control wiring
- Direct reference to LVU804171
- Compact 1.5-amp diode for the listed tractor applications
- Useful for correcting verified open, shorted, or leaking-diode behavior
Replaces Part Numbers
- LVU804171
Common Uses
- Replacing a diode that reads open in both directions
- Repairing reverse-current leakage or circuit backfeed
- Correcting a protected control circuit after the underlying short is repaired
- Restoring the intended relay or safety-interlock logic
Technical Specifications
- Product Type: Electrical Diode
- Current Rating: 1.5 A
- Approximate Dimensions: 0.7 x 0.4 x 0.2 in
- Approximate Weight: 0.01 lb
- Condition: New aftermarket
Installation & Fitment
- Disconnect battery power and use the correct tractor wiring diagram
- Identify why the original diode failed, including shorts or incorrect accessory wiring
- Match polarity and terminal position exactly; reversing a diode changes circuit behavior
- Reconnect power through the proper fuse and test every affected interlock and function
Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: How do I test the old diode? A: Use a meter’s diode mode with the circuit isolated. It should conduct in one direction and block in the other.
Q: Does the stripe or polarity direction matter? A: Yes. A diode installed backward blocks the intended current path and can make the circuit behave incorrectly.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
