My golf cart is working great again! *by M***N on Reviewed in the United States on July 14, 2024* Good quality and restored my cart to perfect working order. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars If using it for a golf cart, you will probably need to make a holding bracket for it. *by S***G on Reviewed in the United States on March 22, 2024* I didn't know it has to work in a certain position, so I had to make a bracket to hold it upright, but it works fine. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Heavy Duty Solenoid *by P***G on Reviewed in the United States on July 20, 2023* This a GREAT replacement for any 48v golf cart. I use these in Club Cars, EZGO, and Yamahas. The main lugs are much larger on these than standard golf carts and you will need to change the terminals out to 3/8 copper terminals. Not a big deal if you have a hand held hydraulic crimper but not so good if you don’t. You can try to drill them out but you will likely just tear up your terminals on your cart but this is a must if you are upgrading your controller to anything above stock. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/83599209-hvacstar-36-volt-400a-main-contactor-solenoid-mzj-400a-compatible](https://www.desertcart.us/products/83599209-hvacstar-36-volt-400a-main-contactor-solenoid-mzj-400a-compatible) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-22*
