Aquamist dimmer circuit:

The circuit PWM's the gauge led, enabled by a solid 12V signal from the purple wire. The dim trimmer on board just attenuates the incoming signal. This controls the duty cycle of the PWM driver to the gauge leds.

If the incoming 12V signal is modulated, it will have unpredictable results. If this is the case, connect the purpose wire directly to the head lamp bulb.

I think the flow problem is possibly associated with semi-freezing transition at the nozzle tip. We have measured the tip temperature of the jet at 20C room temperature, we recorded a 5-degrees drop.
