Battery Switch Relay DK236A DK237 for FAW CA151 24V 100A
A 24V 100A battery switch relay that cross references FAW DK236A, DK237 and DK137, fitted to the FAW CA151 heavy truck and other commercial vehicles. It controls the main battery circuit between the starter motor and the vehicle electrical system, allowing remote disconnection for safety and maintenance. Supplied in neutral, customised or CHINO branded packaging with a 12 month warranty from B/L date.
MOQ 10 pcs · Free samples, freight at your cost · Neutral or own brand packing · 12 month warranty from B/L date
Key Benefits

- 100A capacity handles high current draw from starter motors and heavy-duty electrical loads
- 24V system voltage matches the FAW CA151 and similar heavy trucks
- Direct plug-in replacement with the original terminal layout and mounting pattern
- Ships in 7 to 10 working days as a stocked fast-moving item
- Twelve month warranty from B/L date protects against early failure in critical systems
Application Scenarios
Where It Is Used
- Fleet workshops replacing failed battery switch relays on FAW CA151 trucks after prolonged use
- Aftermarket distributors stocking FAW electrical components for heavy truck and engineering vehicle fleets
- Repair chains diagnosing trucks that fail to start due to a failed battery switch relay
- Engineering machinery operators replacing relays on excavators and construction vehicles with FAW-based electrical systems
Who It Is For
- Truck parts importers who buy against FAW OEM numbers
- Aftermarket distributors serving Chinese heavy truck and engineering vehicle markets
- Fleet maintenance managers running FAW CA151 trucks and related vehicles
- Repair shops that stock relays by OEM number and voltage
Problems It Solves
Symptoms on the Vehicle
- Trucks that fail to start due to a failed battery switch relay preventing power to the starter
- Relays that overheat or weld contacts under high current load, causing permanent circuit closure
- Original relays that are difficult to source and expensive through the FAW dealer network
- Mixed vehicle fleets that would otherwise need separate part numbers for DK236A, DK237 and DK137
Technical Features
- 100A high current switching capacity for heavy-duty battery circuits
- 24V commercial vehicle system voltage with compatible coil and contact rating
- Direct replacement for DK236A, DK237 and DK137 with identical terminal layout
- Robust relay housing suitable for under-hood or cab-mounted installation
- Mechanical and electrical protection against overcurrent and short circuits
- Sealed construction to resist dust, moisture and vibration in harsh environments

Compared With the Alternatives
| FAW dealer original relay | Same fitment and performance 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 system voltage and current rating; a universal relay would be under-rated and risk failure |
| Used or reclaimed relays | New units carry a 12 month warranty from B/L date; reclaimed stock carries none and may have degraded contacts |
Use Guide
- Confirm the vehicle is a 24V system before fitting
- Match the terminal layout and mounting pattern against the old relay before ordering
- Isolate the battery, disconnect the failed relay from the main electrical panel, and install the replacement in the same orientation
- Test the relay by engaging the start circuit and verify full contact closure and release
- If the relay fails to engage or remains closed after release, check the control circuit and battery voltage before condemning the relay
