Functional. Be careful when tightening nuts...strips very easy
Quality is questionable. The poles will strip way to easy. So be careful when fighting down. I had to use a stack of washers on top of wire to keep the nut tight. As far as functionality goes ..been doing great for over a month.

Inexpensive part and YouTube knowledge lead to quick fix
Size: 96158T-1PCS
Solenoid went out on boat. After viewing multiple videos on YouTube I figured that my solenoid was bad. Ordered this and received a day later. Replaced the other one and this worked perfectly.
