Holy Thread dig Batman! After a year, I'm back on this thread. I do a lot of lurking looking at electric motors i've scrounged and solar info, but i've finally gotten everything together to complete this. I have built a mechanism out of the passenger side window motor of an early 90's oldsmobile. My wife's first car that still sitting out behind her dad's barn. It is the geared arm assembly. Travels in a slight arc so I made an articulating arm that slides a wooden door in a track. Works great. I'm mounting everything on a particle board panel in my shop that can then be mounted to the coop. I've mounted my limit switches to stop travel, I've got dpdt relays, a 12v timer, solar panel, charge controller. I had a "new" 5AH battery from the emergency stop system on a trailer, but it probably sat idle for a few years before I got it so now it won't take any charge. Any benefit to running a couple of 6V in series? I'm planning on getting a 7AH SLA 12V right now. I have the wiring diagram posted earlier on here, but I'm still trying to understand what wire goes to which pin on the relay. I'm looking for " connect the wire from the timer to pin 5 on relay l then run a wire out of pin 8 to relay 2, pin 1." You get the idea. I've been hooking my solar panel up to some car batteries just to learn more about how it works. Yesterday was very sunny, and the output was 22 volts. I didn't think to check the amps but I will. I'd appreciate any other thoughts or advice on this. My last 2 harebrained scrounger projects worked beautifully, bt
