Hi, this is my first post, hope I'm in the right place. I need help with a home project. I have 2 solenoids, but only one operates at a time, with about a 16% duty cycle each. The solenoids use 12.6 volts, and they're about 3.5 ohms each, 18-gauge copper enamel wire. The solenoids are switched with rotary switches, with (2) 10-amp diodes each for flyback protection. It seems if I could get the resistance exactly right, the solenoids would pull with a lot of force (enough to make things work). The problem is that there is some fine line of enough current, versus too much current, and I don't know what to do. I tried to calculate it out and thought I needed a 1-ohm resistor for each solenoid, but I can't make it work. Any help would be appreciated, TIA.
