Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
- International trucks using a 12V 100A three-terminal grounded-case solenoid
- Equipment using AR73144 or SBC4201-series continuous-duty solenoids
- Auxiliary power, liftgate, hydraulic, and battery-isolation circuits with matching specifications
Product Overview
This is the type of relay used when a circuit must stay energized for more than a quick starter crank. A hot housing, heavy voltage drop, chatter, or power that disappears under load can signal burned contacts or a weak coil. Choose it by electrical specification, not truck badge alone: 12 volts, 100 amps, three terminals, and a grounded mounting case must all match.

Frequently Asked Questions
Q: What problem is this part commonly used to address? A: This is the type of relay used when a circuit must stay energized for more than a quick starter crank. A hot housing, heavy voltage drop, chatter, or power that disappears under load can signal burned contacts or a weak coil.
Q: How should fitment be confirmed? A: Match the original part number first, then compare the connector or fittings, mounting points, dimensions, and machine or engine serial information.
Q: Is this an original equipment manufacturer part? A: No. This is an aftermarket replacement part for compatible applications.
Q: Can another fault cause similar symptoms? A: Yes. Wiring, grounds, hoses, filters, related controls, and mechanical wear should be tested as part of the diagnosis.
Q: What should be checked after installation? A: Confirm secure connections, normal operation, and no leaks, heat, binding, or warning indications before returning the equipment to service.
