Ok, I have been pondering this more than I should be considering the amount of work I have stacked up but I love trying to figure things like this out.
So a little back story: I am trying to come up with the best solution for a self-driven 1 man stand. I plan to use a mobility scooter for the self-driving part and a typical harbor freight winch for the lifting part. The issue arises when you realized that mobility scooters are 24v (2 12v batteries in series) and most winches are 12v.
As previously discussed in this thread: https://tinyurl.com/56sw7tb3
• Both circuits require HIGH amperage so this eliminates most easy solutions. ie a simple 24-12v transformer
• It is best to not drive the winch off of just one 12v battery because of uneven drain and re-charging concerns.
• Another concern I have (with the trolling motor selector switch solution) is accidentally powering the winch with 24volts or the scooter with only 12v.
Therefore, I have come up with the circuit below using 4 typical lawnmower solenoids like this: https://tinyurl.com/vfthrh3d and a 3-position DPST (double pole, single throw) switch like this: https://tinyurl.com/54kveys4
Now if all of my fellow, amateur (or professional) mechanical/ electrical enginenerds would kindly tell me why this circuit won't work or what my next obstacle is that would be great.
I know of at least one concern, let's see if you guys can find it and more.
Thanks
