I've been through six Mighty Mule gate openers in six years because the tiny relays that provide power to the actuators can't handle the current draw. The relay provides 12vdc to open and reverses the 12vdc to close. want to piggy back off of the relay output to a circuit supplied directly by the battery with relays or solid state devices that can better handle the high current load of the actuators. My electronics training was in the army in 1962 and I've been out of the field ever since, so I'm not only stale but am from the tube era.
Any suggestions?
