Compared With the Alternatives
| DONGFENG dealer original relay | Same fitment and current rating at aftermarket pricing, but without the dealer part number on the box unless you order branded packaging |
|---|---|
| Universal 12V battery relay | The 24V 100A unit matches the original DONGFENG system voltage and current capacity; a universal relay may not support 100A or 24V reliably |
| Used or reclaimed relays | New units carry a 12 month warranty from B/L date; reclaimed stock carries none |
Use Guide
- Confirm the vehicle is a 24V system before fitting
- Match the connector pattern 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 key to the start position and verify full battery connection
- If the battery does not connect, check the ignition switch output and battery terminal connections before condemning the relay
