192507 Starter Solenoid for Husqvar-na 582042802 532192507 582042801 Craftsman YS4500 LT2000 YT3000 Lawn Mower Tractor Parts

What It Is

This is a 12V starter solenoid (OEM cross-reference 192507/532192507) that acts as a relay between your battery and starter motor. It’s designed for Husqvarna, Craftsman, and other lawn tractor models with Briggs & Stratton or Kohler engines that use a standard 3-post, ground-switched solenoid.

Fitment & Compatibility

Before buying, confirm:

• OEM numbers: 192507, 532192507, 582042802, 582042801 – these are the direct matches. Also replaces 539131706, 925-04280.
• Machine models: Fits Husqvarna YTH series, Craftsman YS4500, LT2000, YT3000, and many Poulan, Murray, and AYP tractors from the 2000s–2010s.
• Physical check: Measure your original solenoid’s mounting hole spacing (typically 2.5” center-to-center) and terminal layout. This unit has two small spade terminals (one for trigger, one for ground) and two large studs (battery + and starter).
• Voltage: Must be 12V DC – not for 6V systems or zero-turn mowers with different wiring.

Key Things to Know

• Quality: Aftermarket replacement, not OEM. Most users report 2–4 year lifespan in normal use. Some units may have slightly thinner gauge wiring than original – fine for stock engines, but not for high-compression or modified motors.
• Installation difficulty: Easy (15–30 minutes). Disconnect battery negative first. Mark wires before removal – the small terminal closest to the large stud is typically the trigger wire from the ignition switch; the other small terminal is ground.
• Common gotchas: If your mower clicks but doesn’t crank, the solenoid itself may be fine – test with a multimeter (12V at trigger terminal when key is turned). Also, this solenoid is not weatherproof; mount with terminals facing down to prevent water pooling.
• Fitment note: Will not work on older models with a 4-post solenoid (e.g., some Prestolite systems) or on mowers with a separate starter relay.

Should You Buy It

If you need a reliable, low-cost replacement for a failed solenoid on a standard Husqvarna or Craftsman lawn tractor, this is a solid pick. It’s not built for heavy-duty commercial use, but for residential mowing it delivers consistent performance at a fraction of OEM cost. Just double-check your mounting pattern and terminal layout before ordering.
