Riding Mower used to "Click" but not crank sometimes. My electrical meter showed that it was OK when tested, but still not reliable. Replaced it with this one. Much heavier duty than the original equipment. Now my mower starts like a charm!

Draws 1 amp of current constant. Good, strong, engagement, and works like a champ. Easy to install. Has two contacts for coil, case is not coil ground. Exactly what I needed.

I used this solenoid to replace my starter solenoid on a four wheeler. Easy instal and works as it should. I had an issue originally getting it to work with the turn of the key. I could jump it across the terminals and get my quad to start. Turns out it was a grounding issue that was easily resolved.

Replacement for a continuous solenoid on an electric golf cart. If you have a gas golf cart and you need to replace the “starter” solenoid, this is not the type you want. They function quite differently and are not interchangeable

I purchased this product because I needed a continuous duty solenoid to keep two 12v batteries wired in parallel charged while driving the vehicle but not engaged while the engine is off, so my engine battery would not lose its charge because of the two house batteries draining it without my knowledge. It took some time to install the system and get my Chevy cargo van ready for some distance camping. But even before I left town, I discovered that the solenoid was getting hotter than I could even touch and my automatic breaker kept cycling. The odd thing was that I didn't have my inverter turned on nor any of my inside lighting (which wouldn't have been much). The only thing that was going on was the solenoid providing power from the alternator to keep the two house batteries charged. Nothing on the device indicates it's a continuous duty device and nothing on the device indicates the rated amperage. I'm quite disappointed that the device I purchased didn't even last for a single camping trip but gave me enough unrest, over perhaps suddenly bursting into flames, that I disconnected the device. And since I purchased the device June of 2019 and it's now August of 2020, I can't even return it for a refund. So, it's a total bust and I would caution other buyers to be aware and make certain you thoroughly check it out before getting into a desolate area and finding that it's just not what it should be.
