Today I did a little work on the HHO System in my Mustang. As I mentioned in Part 4 I received the new PWM and LCD display to replace the one that came with my current system from HHO Monster. These new units are what are being shipped with this system now and provide a steady current to prevent amp and current fluctuations allowing for a more stable signal for the fuel cells to produce hydrogen with.
The PWM, as can be seen in the picture, looks the same as the old. This will change in later boxes as the adjustment knobs are no longer functional. I placed it in the same location, but the wiring is a little different, so I had to run two new ones into the cabin that connect with the new LCD display.
I removed the previous panel I made for the old LCD display, switch, and Air/Fuel Gauge. The new LCD is in a larger box, so I need to do some creative adapting if I want it to fit in the same space. But that’s a different project I won’t cover here now. There was some extra wiring needed to install this LCD, since it is controlling the PWM now from here, thus the two wires mentioned above. I removed the Air/Fuel Gauge since it is a basically a useless device. I’m thinking the Kiwi MPG will fit here nicely giving MPG feedback, which is far more important than the light show of the Air/Fuel Gauge. The Kiwi will also tell Check Engine Light Codes, should they occur.
Once hooked up, all seemed to work well, I was able to set the controls on the LCD and the fuel cells were generating hydrogen. Right now the LCD is only temporally installed as I design the rest of the panel.
More to come.
