perfect for harbor frieght wireless 2500lbs winch
This solenoid worked great for my habor frieght 2500lbs wireless remote winch. My winch stopped working from the remote. I swapped the solenoid out and it is back to working great again.

Winch , solenoid for your new or replacement build.
Twelve volt solenoid for winch works well. The threads between the nuts and the studs are a little rough . When paired with a remote wench controller , the relays seem to have a nice crisp engagement. The plastic casing on the solenoid seems to be of good quality. Some type of thermal set plastic.

Easy to wire up and worked well with no issues. Has the same flipity flopity as another review. Hopefully it last a while. If not, it was cheap enough not to worry really.

6mm studs, 10 mm nuts, meant for two wire motor.
This reversing relay has small studs with 10 mm nuts- 6 mm studs I believe. The two internal relays are operated by the each one of the outer spade terminals being either energized or grounded to the center terminal. The solenoid terminals do not appear to require a certain polarity so either positive or negative control is possible. The default seems to be ground control since a pigtail between the center pin to the positive battery stud is included. A wiring diagram is not included but the arrangement of power supply was good for my situation: The positive and negative terminals are alternated to the two motor terminals by energizing one solenoid at a time. If both solenoids are energized simultaneously, the unit will not short out. This is meant for a two wire reversing motor where battery power and ground are only provided to motor through this relay, not three wire motors where the ground is provided directly from motor to battery.

Buon acquisto
Montato per comandare il verricello della barca funziona perfettamente. Qualche difficolta' nei collegamenti perche' la confezione non contiene alcuno schema, comunque girando in internet ho risolto. Direi ottima alternativa a prodotti di marca nel settore nautico ben piu' costosi.
