Two guys have asked for the math, so I will post it to the whole list.
This is for the value of a "dropping" resistor to be used in series with an
LED. The purpose of the dropping rsistor is to keep the current in the LED
below the value that will fry it. LED's do not obey Ohm's law. In the
I haven't done this. I don't even have a winch, but the electronics should be
dead simple. Across the output terminals of each solenoid, put an LED with an
appropriately sized dropping resistor in series. When the solenoid is closed,
or welded shut, the LED will be off. When the solenoid is
