2007 H3 Hummer Installation

 
   
 
   
The PEC generator is behind the first grill opening, to the right of the passenger side headlight.

 


 
Very neat installation.
It takes a trained eye to recognize the generator components.

 
This is a picture of the PEC generator installed behind the front grill. It is located to the left of the radiator.
  • Notice how neat the electrical wires are.
  • The clear hoses pass through an opening in the radiator support frame, on their way to the water supply tank.
  • It is important not to have sharp bends in the hoses.
  • It is also important for the hoses not to have drip loops in them. Drip loops allow water to collect in a low spot - which becomes an obstacle for the vapors to pass through.

 
The circular cap in the bottom left of the picture is the top of the water supply tank.
  • The water supply tank has two hoses on the bottom that can not bee seen in this picture. The hoses connect to the PEC generator.
  • The vapors produced in the PEC generator pass through the water supply tank, where foam is eliminated before it can reach the engine.
  • The vapors pass through the top hose on the water supply tank and from there go straight to the engine Air Inlet.
  • Once in the Air Inlet, the vapors mix with the metered air that is supplied to the engine.
  • The top cap of the water supply tank is designed to pop off should there be an engine backfire.

 
This is a picture of our Go-no-Go vacuum switch.
  • When the ignition switch is turned on, it supplies 12 volts DC to the vacuum switch.
  • When the engine is running, the vacuum switch supplies the 12 volts DC that powers the PEC generator.
  • When the engine stalls or when it is turned off, the vacuum stops, thus the vacuum switch turns off; regardless of the position of the ignition switch. In other words, the vacuum switch is a fail safe. The ignition switch must be on and the engine must be running for the PEC generator to operate.

 
This is a picture of the vacuum hose connection on the motor. The vacuum pressure of the engine is used to turn the PEC generator "on and off".

 
This is a picture of the 40 amp power relay (in the center of the picture).
  • The relay is operated by the vacuum switch. In other words, the switch turns the relay on and off.
  • The relay passes 12 volts DC from the positive terminal of the battery to the PEC generator.
