Truck Starter Relay for ISUZU SS112 SS124 12V 24V 100A
A 12V or 24V 100A starter relay assembly that cross references ISUZU SS112, SS124 and 30A29, fitted to ISUZU trucks and other commercial vehicles. It controls the high current flow from the battery to the starter motor during engine cranking and prevents the ignition switch from carrying the full load. 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

Use Guide
- Confirm the truck is a 12V or 24V system before fitting
- Match the physical housing and terminal 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 key to start; it should engage with a distinct click and the starter should crank
- If the relay clicks but the starter does not turn, check the battery voltage, ground connection and starter motor
