PWM (ver2)

Basically it's the same internal components as the PWM Cluster Box only a bit more compact and asthetically pleasing.
Another quick Video.

This box was made for my wife's car. In her car I will go more the OEM look. The gauges will be installed either in the dashboard or in pods on the A- pillar.

This is the dimensional drawing for building the PWM enclosure.

PWM Gauge Cluster

I finally got around to putting the cluster together. The PWM adjustment knob is at the lower left. Basically all the components were put into a Radio Shack project box. It works like a dream.

Here is a quick video

It shows the guts and the wiring. I used 8 & 10 AWG wire.

Unfortunately, all I had was red.

This is the wiring diagram for the PWM with both the volt meter & the ammeter incorporated in it. This configuration will allow monitoring of the adjusted voltage being sent to the generator as well as the amount of amps the generator draws. By using a PWM you can make a heavy (28%) concentration of KOH electrolyte without drawing amperage which would normally fry your HHO generator.
