  • Relays that overheat and weld contacts shut during repeated cranking or high load conditions
  • Original relays that are slow to source and expensive through the dealer network
  • Mixed fleets that would otherwise need separate relay part numbers for ISUZU and KOMATSU models

Technical Features

  • High current switching at 100A for 24V commercial vehicle systems
  • Single pole, normally open contact configuration for main battery circuit control
  • 24V system voltage compatible with ISUZU and KOMATSU commercial vehicles

Honest Comparison

Compared With the Alternatives

ISUZU dealer original relaySame fitment and current rating at aftermarket pricing, but without the dealer part number on the box unless you order branded packaging
Universal 12V battery relayThe 24V 100A unit matches the original system voltage and current load; a universal relay may not handle the full load safely
Used or reclaimed relaysNew 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
  • Isolate the battery, unplug the failed relay from the control panel and fit the replacement in the same orientation
  • Test the relay by turning the ignition key to start; the battery should engage without delay
  • If the relay clicks but the engine does not crank, check the starter motor and battery connections before condemning the relay
