Hey everyone...PROBLEM SOLVED
But before I go into what I found and how I fixed it, I feel it necessary to acknowledge that some of you guys REALLY DO KNOW THE DIFFERENCE between a butthole and a hole in the ground.
ORIGINAL: revelation
hey pro. I know there is no sine wave in a dc signal, but you have to remember that those power panels change the voltage/current (however u view it..) going to the glow plug by means of "frequency modulation". Meaning that the smooth dc signal is broken up into short or long, fast or slow pulses to either increase or decrease the amount of power fed. That is what the whine is. Not from hi voltage as was suggested, but from all sortss of funny frequencies inside the panel as it modulates the dc pulse.
It pays to save the boxes that the products come in...... I quote from the feature description...
"State-of-the-art IC-controlled variable pulse power supply for the glow plug"
......as Rev stated above[8D]
Question for you Rev...... (since you seem to be electronicaly inclined) Instead of going out and getting a new panel, is there a way to sheild the current panel ? Redirect the RF so to speak away from the hull. For a pic of my setup, find my thread of my boat starting stand.
