Replacement 100% OEM Match and Replacement Review: Used on a LawnMower that was getting hard to start, works GREAT! - 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!

The Max Short Time Current can endure 300A; But if u want to keep working for more than one hour without break, the current need be about 80Amp; Otherwise the body of solenoid will be so hot and burned **Q: How many miliamps does it require to activate the solenoid? I want to make sure my momentary push button switch can support activation of this solen** A: I believe the coil resistance is around 14 ohms which would make the current around 900 milliamps. But Rember thr collaspe of the coil during disconnect creates large spikes across a small switch and burn the switch contacts, therefore I would a 1 amp @600 volt despising diode across the solenoid coil to protect your switch contacts. **Q: None of the posts are labeled. Which one is the on switch?** A: This is generally used to power large loads like a starter or like my app. Four bilge blowers. The big posts on the side are battery cable in than wires out to the load. The small posts are power and ground to run the solenoid. Connect one to ground one to the switch. You might want to test the small posts with an ohm meter. Make sure neither is to ground . **Q: why is his thing getting so hot?** A: Give me some background info, how many amps drawn ,voltage and application ## Customer Reviews ### ⭐⭐⭐⭐⭐ Used on a LawnMower that was getting hard to start, works GREAT! *by M***H on June 18, 2024* Riding Mower used to "Click" but not crank sometimes.

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. ## Frequently Bought Together - Max 300A Heavy Duty Solenoid Relay Nickel-Plating for Golf Carts, Winch, Marine in Rush 12VDC - TKDMR 160Pcs Copper Wire Lugs AWG2 4 6 8 10 12 with Heat Shrink Set, 80Pcs Battery Cable Ends Ring Terminals Connectors Tubing Assortment Kit - Max 300A 12 Volt Duty Solenoid Relay 4-Terminal for Golf Carts Heavy Duty Winch Marine in Rush SPST 12VDC 12V Solenoid Relay Nickel-Plating --- ## 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.vn/products/68803701-max-peak-instant-current-300a-heavy-duty-solenoid-relay-nickel](https://www.desertcart.vn/products/68803701-max-peak-instant-current-300a-heavy-duty-solenoid-relay-nickel) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-18*
