- Auto electrical repair shops that stock relays by current rating and voltage
Problems It Solves
Symptoms on the Vehicle
- Battery circuits that remain live after the ignition is off, risking parasitic drain
- Starter motor that fails to engage due to a relay that cannot close the main contact
- Relays that overheat or weld contacts under high load, causing permanent circuit failure
- Original FAW relays that are slow to source and expensive through dealer channels
- Mixed vehicle fleets that would otherwise require multiple relay part numbers for the same function
Technical Features
- 100A switching capacity for main battery circuit control in 24V commercial vehicles
- 24V system voltage compatible with FAW J6 and similar heavy trucks
- Electromechanical relay design with sealed contacts for dust and moisture resistance
- Built-in thermal protection to prevent overheating under sustained load
- Designed for mounting on engine compartment relay panels or control boxes

Compared With the Alternatives
| FAW dealer original relay | Same fitment and electrical rating at aftermarket pricing, but without the dealer part number on the box unless you order branded packaging |
|---|---|
| Universal 100A battery relay | universal relays require a wiring adapter and may not support the correct pin configuration |
| Used or reclaimed relays | New units carry a 12 month warranty from B/L date; reclaimed stock carries none and may have degraded contacts or insulation |
Use Guide
- Confirm the vehicle is a 24V system before fitting
- Isolate the battery, unplug the failed relay from the control panel, and install the replacement in the same orientation
- Test the relay by turning the ignition to ON and verifying the battery circuit closes and opens correctly
- If the relay clicks but the battery remains disconnected, check the control signal wire and ground connection
