Diagnosis

Problems It Solves

Symptoms on the Vehicle

  • Battery circuits that fail to engage due to a burnt or welded relay contact
  • Starter motors that do not crank because the relay cannot carry 100A under load
  • Original relays that are slow to source and expensive through the DONGFENG dealer network
  • Mixed fleets that would otherwise need three separate relay part numbers for different vehicle types

  • 100A main contact rating for reliable battery circuit switching
  • 24V DC system voltage compatible with DONGFENG DFM trucks and heavy machinery
  • Single pole, normally open contact configuration for battery isolation
  • Housing with original connector pattern for direct replacement
  • Internal coil and contact assembly designed for high vibration environments
  • Sealed construction suitable for under-hood or cab-mounted relay panels

Honest Comparison

Compared With the Alternatives

DONGFENG dealer original relaySame fitment and current rating at aftermarket pricing, but without the dealer part number on the box unless you order branded packaging
Used or reclaimed relayNew units carry a 12 month warranty from B/L date; reclaimed stock carries none and may have degraded contacts
Fitting

Use Guide

  • Confirm the vehicle is a 24V system before fitting
  • Match the connector housing and pin layout against the old relay before ordering
  • Isolate the battery, unplug the failed relay from the relay panel and fit the replacement in the same orientation
  • Test the relay by turning the ignition to start – the main contact should close with a distinct click
  • If the starter does not engage, check the battery voltage, earth connection and ignition switch signal before condemning the relay
