Review: Merci. - très satisfait Review: Great for high amp cooling fans! - I own a custom automotive shop, and I've used these 12V continuous duty solenoids on multiple custom builds with excellent results. I primarily use them to power high-amp electric cooling fans, especially on LS and Coyote swaps. I've also used them to power electric A/C compressors without any issues. In my experience, even quality Bosch-style 4-pin relays can eventually fail when they're exposed to constant under-hood heat in the Texas summer. These continuous duty solenoids have proven to be a much more reliable option for high-current accessories that see long run times. If you're running A/C fan controls, I highly recommend pairing the solenoid with a 3-wire diode. It keeps the circuit working correctly and prevents unwanted feedback, while allowing the solenoid to run cool even during extended operation. The build quality has been excellent, they're simple to wire, and they've been dependable across several customer builds. If you need a heavy-duty relay solution for electric fans, electric A/C compressors, or other high-current loads, these are a great choice and have earned a permanent place in my shop. ## Features - Specification 4-pole battery isolation solenoid valve: Voltage: 12VDC; Resistance: 14Ω; Capacity: 10.2W; Maximum transient flash current: 300Amp; but Continuous Working Current recommend under 150 Amp,Bracket:Straight;Bracket mounting:Holes 5/16 x 19/32 2-13/64 on center - Materials 4 Terminal Max 300A 12 Volt With 2 Copper Point Continuous Duty Solenoid Relay ,The The electromagnetic relay adopts high-quality components, Coil Roll is using 180℃ copper wire, Cover is Nickel-Plating, Meet Environmental Plating Requirment.The Nickel-Plating outer layer and the inside of the canned coil, suitable for use in any environment. - Replaces Parts Number This Continuous Duty Solenoid Relay Replacement For 70-111224, 3635820, 1114208, 1114218, 1114223, 1114534, 1114547 - Function good saver to your battery ( Max Flash Current 300A).

Not sure what the duty cycle of the coil is rated for. That would a guestion for the manufacture to answer. My replacement was for a three pole and what you are questioning is a normal state when used in you configuration i.e. golf cart.. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Merci. *by C***T on 20 March 2025* très satisfait ### ⭐⭐⭐⭐⭐ Great for high amp cooling fans! *by M***S on 18 July 2026* I own a custom automotive shop, and I've used these 12V continuous duty solenoids on multiple custom builds with excellent results.
