Darryl, I would like to buy one of your door opener kits without the control unit. I will be setting them up to work with an auxiliary circuit on my alarm controller. Several years ago, I had a door lock solenoid go bad. I replaced both solenoids with actuators. The stock solenoids used three wires (ground, open, and close) and the actuators operate by reversing the polarity on only two wires so I had to set up a simple relay circuit. The actuators have worked flawlessly, and since the door lock pulse unit is only driving small relays, it should also last forever. While I had the doors apart I also installed door openers. Unfortunately, I used solenoids. They do work, and everyone is impressed, but if my battery gets even slightly depleted, the solenoids (which require a lot of power) do not reliably unlatch the doors. My doors are aligned perfectly. I can use my little finger to pull the handle up half way, and the doors unlatch and open smoothly and fully. I could run larger wires to the solenoids, or try different solenoids but I think your actuator solution would be much easier. I'm not at all concerned about their reliability since actuators are so widely used in the auto industry, and yours are the best the DeLorean experts have seen. Gary (at) IN2TIME.com www.IN2TIME.com
