I have been plagued with strobe noise ever since my -8 was wired by one of the "pro's". I have Aeroled multi voltage nav/strobes. I recently rewired my strobes hoping to eliminate the pulsing I hear with the strobes on. I ran separate ground wires for each strobe and grounded them all at the same point, the main ground bus. I grounded the shields independently on the light frame, and at a single point on the main ground bus. This was per Aeroleds suggestions.
I still get the pulsing noise in my headset. Very frustrating after all the work to rewire them.
Some other clues I've picked up along the way. The noise is not present when running only on the battery, and while on the ground. Ill have to try this airborne by shutting off the alternator, but I don't think this will make a difference. The noise only comes through the intercom. The pulsing does seem to change frequency slightly based on engine RPM. I also get a slight hum when my smoke pump is turned on.
Can anyone offer suggestions on where to look next? Does this sound like an intercom problem? It appears at first glance that the intercom is grounded correctly. Your help is appreciated!
