Electronic Controller Device (Analog)
Electronic Controller Device (Analog) - More DIY How To Projects]]> Sparker94 I made this analog circuit for two reasons. One: To stop my wires from melting due to too much current. Two: To limit the load on the alternator. Instead of the lights on a trailer going through the tail light circuit on the vehicle, which caused mine to melt, It will pull current directly from the ...
