🔌 Function

Passes current in one direction only in the starter circuit, suppressing the reverse voltage spike produced when the solenoid coil is de-energised.

⚠️ Common Signs of Failure

• Voltage spike on shutdown upsetting or resetting the instrument panel
• Starter solenoid chattering or holding in after the key is released
• Body of the diode cracked, discoloured or heat-marked
• Reads short or open in both directions when tested
• Repeated failures of other electrical items on the same circuit

🛠️ Service Notes

• Confirm the starter is 874304 before ordering — this diode is listed against that starter only
• Check the solenoid and its earth path at the same time; a failing solenoid is what destroys the diode in the first place
