Product Overview
When the key circuit is working but the starter receives no battery current, the starter solenoid may have worn contacts. This replacement is for the matching John Deere terminal and bracket design used across several older riding mowers.
A single click is not a complete diagnosis. Load-test the battery and inspect cables, grounds, interlocks, and the starter before replacing the solenoid.

Frequently Asked Questions
Q: Will this solve every no-crank problem? A: No. Battery, cables, key switch, safety interlocks, and starter condition must be checked.
Q: Does STX38 fitment depend on deck color or serial? A: Yes. Use the listed configuration and confirm AM104036/AM100128.
Q: Is a click proof the solenoid is good? A: No. The coil may click while burnt internal contacts fail to carry starter current.
Q: Is it OEM John Deere? A: No. It is an aftermarket replacement.
