Local farmer had me add a guidance system, cb radio, and planter monitor to his tractor. To power all of these add-on devices I had to create my own circuit. When planning for this ahead of time I ordered a solenoid rated for the anticipated amount of amperage draw. I found that most of the generic solenoids at my local parts store are intended for a starter, ie. they are rated for "in-rush" amperage and a specific amount of time they can withstand that amperage, usually in minutes. I avoided these "starter" solenoids and ordered the solenoids labeled "continuous duty". After replacing two of these "continuous duty" solenoids due to internal failure I just chalked it up to poor quality. Looking for a higher quality solenoid on the web I started to notice the "continuous duty" labeled solenoids also had a amp/time rating suggesting they were not intended to be turned on and left on all day. Are my expectations of "continuous duty" not realistic? The circuit needs to sustain 30 amps. I am looking at some aircraft solenoids next. Any suggestions or opinions welcome.

Gas golf carts as you may know use a primitive stop/start system so that the starter/generator solenoid stays engaged (connected, it's belt driven) as long as the your foot is on the gas. Thus the continuous duty solenoid. https://www.golfcartgarage.com/ezgo-...iABEgIRb_D_BwE Hopefully this link works. Aftermarket parts are easily available as carts are often customizedComment
