HHO Gas Wiring…Don’t Forget The Relay!
The HHO gas wiring has one important necessary feature: its ability to automatically turn on and off the hho gas generator. Instead of using a toggle switch to operate the hho system, a relay is installed. What is a relay? A relay is an electrical switch that controls another circuit. It is also a device that contain an electrical winding motor inside which when powered up, will allow connection of 2 wires or circuits together. Example: Let us say you have a 4 terminal relay…if winding motor has terminals A & B and if battery power is supplied to each end of these terminals, the remaining 2 contact terminals C & D will connect together.
This is important in our HHO gas wiring which needs to be shut off when we stop the engine. If we are using a toggle switch to turn the HHO generator on, there is a chance that we can forget to shut the toggle switch off. If we have a relay, then power can can be supplied automatically to the hho gas generator. When power supply to the HHO generator is connected to a relay, everything can be controlled from the ignition key circuit. Still other installers, can connect the power supply to the fuel pump so that the hho gas generator only works when the fuel pump is on. This is a safe way to control hydrogen gas cars which can prevent running the hho gas generator continuously when you are not driving the car.
When installing a hho gas wiring relay, there are usually 4 terminals:
2 terminals for the winding, one ground and one from ignition switch or any control circuit source.
2 terminals for the controlled circuit (in this case, the power supply to the hho gas generator: one incoming wire from a fused battery supply and the other outgoing wire to the hho gas generator power supply).
Shown on Utube video below is a simple hho gas wiring relay installation set up showing all of the above connections. For your safety, we recommend the following:
use #10 gage wires
use #30 amp or higher rating relay
locate the relay away from heat
secure all connections and make them tight
In you notice in this video, the hho gas wiring relay installation is easy and you can buy this relay from any local automotive parts store. Always specify the correct amperage rating to the vendor to prevent overheating the motor winding inside the relay. As recommended by the video maker, always get a certified mechanic to assist you when installing relays in your hydrogen gas cars. (ATS also provides this service if you are a member including all the necessary wirings assistance for your hho generator).
