I know what to do... fire 'em all ;-)



Replace them with an electric gate closer. I still see lots of those
24 V satellite motors around. All you need are two wires to the motor,
a 24V 5A supply & a reversing switch. There are a pair of adjustable
limit switches inside that can be set for full open & fully closed. An
On/Off switch for added safety, in case someone tries to stop it by
putting their hand in the wrong place. I have a pair of 18" jacks that
I'm going to use on the swung gates at the end of my driveway. A couple
old C-band sat controllers for the power supplies, and an eight button
RF remote for the truck. The RF remote & matching relay output
receiver are about $10 on Ebay. I should have less than $20 in the pair
of controllers.

The two eight foot pieces of 6" black iron pipe cost me a lot more
than that. The old gate posts are wood, and the gates change position,,
depending on the amount of rain.
