TAKE A LOOK AT THE ALTERNATOR POWER WIRE IN THIS PHOTO
 
THE WIRING DONE HERE IS VERY DETAILED AND VERY CREATIVE. HOWEVER THERE IS A PROBLEM, THIS IS HOW YOU MAKE A RESISTOR. A RESISTOR IS A DEVICE THAT REDUCES THE ELECTRICAL VOLTAGE. THIS IS IN A MODEL T, THE ONLY LOAD IT HAS IS LIGHTS […]

Electricity is very much like water, if you do not provide it with clean and clear paths it will take the path of least resistance. The first thing that I recommend when modifying your electrical system is to install a […]

As always the basics first. Cords are not a battery hold downs! Stop using them! Make sure the battery is secure. There is an ancient Buddhism saying “man who does not check his battery will invite Vicky to car-b-cue on 4th of July weekend” (Sorry Buddha couldn’t resist). The fact is batteries are heavy, they […]
