Does anyone know of a filter to remove generator noise from audio? I now have the ANR kit in my headset and now can hear the noise. I assume it was there all the time but I couldn't hear it. The kit works great.

Jim,
Make sure your B-Lead is shielded, if it is make sure the shield has not broken free from it's ground tie-in. That's where the noise most likely coming from.

No I actually meant B-Lead ... the main cable running back from the alternator/generator to the main bus.

Cubes has a good point though. If you think the noise you hear could be ignition noise, make sure your p-leads are shielded correctly as well.

Jim, take the alternator to a shop and have them check for bad diodes.
