Hydrogen buildup in “on-demand” generators. -If I have my car on but not running will the gas build up in my car?
Hydrogen buildup in “on-demand” generators. – If wired correctly, NO, there will be no gas build up.
Ideally you connect to a spot that is only on when the engine is running. Often this spot exists in the fuse box, or your fuel pump is wired this way. Tap into that wire to activate the relay that sends electrical power to your hydrogen generator. When the vehicle engine stops the relay is switched off and power supply to the hydrogen generator is switched off.
