Hi Dave,

If this is Dave Perry, it was nice to see you in Texas, at the Seminar.

There are two possibilities.
In order of probability, first, I would investigate dirt on either the fader control, or the volume control, both of which are rheostats. If your client's radio has either control directly contacting a contaminated section, it can cause continuous noise. I have had this occur with my '85's Bose unit's fader. I have had good success by rapidly working the fader control back and forth until the problem disappears. Worked fine for the car's PV last year. Hasn't reappeared, yet. Of course, the proper way to handle this, is to get in there with some carbon tetrachloride.
The second, and less likely scenario, would be poor contact at the speaker connectors on the back of the radio. Again, this happened to my unit, twice, in the past. The connectors looked to be aluminum alloy, and showed characteristic white oxidation. My speakers were weak, and I feared the dreaded "Amplifier Syndrome". The terminal cleaning corrected the problem, both times.

Dave, Had/have this problem with my 89 as well. Swapped the headunit and it still made the noise. I think it is either the amps or a ground. I found my ground on the power antenna was disconnected. Reconnected it and it reduced the static. (some still there) Also check the grounds for the Bose amps. If there is an open it will attempt to ground through the head unit causing static. The amps could also be bad, but try the grounds first. Eric

With radio playing have him grab the antenna and see if static stops. If so, replace antenna & clean grounds.
