Product Overview
A single click with no crank, intermittent starter engagement, welded contacts that keep the starter running, or heat-damaged studs can point to the solenoid. Battery condition, cable voltage drop, ground, key switch, safety circuit, and starter motor must be tested first.
The contactor uses a low-current control signal to connect battery power to the starter. Its 100-amp application rating, coil circuit, duty cycle, and terminal layout must match the machine.
Match 12V, 100A application, four-terminal arrangement, mounting bracket, stud size, coil grounding method, original number, and equipment wiring diagram.

Frequently Asked Questions
Q: Can a bad battery make the solenoid click? A: Yes. Load-test the battery and measure cable voltage drop.
Q: Why does the starter keep running? A: Welded solenoid contacts or a stuck control signal can be responsible; disconnect power safely and test both.
Q: Can I replace it with any four-post solenoid? A: No. Coil grounding, current, duty, stud size, and wiring must match.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
