Window Accelerators for your Ferrari!

Got slow windows in your Ferrari 308, 328, 348, Mondial, Testarossa, or Dino? These neat electronic gizmos will make a huge difference. How do I know? I have them in my car! HOW DO THEY WORK? Because of the way the window motors work in many old Ferraris, there is a long electrical path from the fusebox to the switch to the motor, back to the switch and then to ground. There is no "local" ground in the door for the window motor because the polarity of the voltage applied to the motor is swapped depending on whether the window is going up or down. These clever little boxes are installed in your doors. They are wired into the window motor circuit. They sense which way the motor is going, and use a pair of relays to provide a local ground, removing a huge chunk wiring from the circuit. This provides less electrical resistance, and the motor goes faster. When I measured the electrical voltage at my window motor without this thing, I got only 7 volts! (That means 5 volts were lost across all the resistance between the fusebox and the motor!) Adding these little boxes brought the voltage at the motor up to 9 volts...a significant increase! It also made my windows go up quite a bit faster. I do not make or sell these, but provide a link to the guy who does, because I think they are cool. And they are only $99 a pair (enough for both doors of a Ferrari). That is one cheap improvement! Read more about installation with THIS PDF. Order from Rodney Dickman!
