W210 Electrical Gremlin

[SocksE420]

My 96 E320 with 71K has starting intermittedly displaying a dim SRS light the last week or so and, less frequently, the factory radio will stop playing. I think I saw the SRS light "flash" when I noticed the radio glitch.
A search of this site suggested a failing voltage regulator - I checked battery voltage with the car off and got 12.46 volts and 14.02 at cold idle, so I've tentatively ruled out the regulator. While running, I was able to check the voltage with a dim SRS light and then I restarted the car and the SRS light was out and the battery voltage was the same both times - 14.02.
In viewing the alternator from underneath I note it is a Valeo and not a Bosch. The car has not left me stranded, i.e., the battery has never been flat. Any thoughts where I should next look? The only other electrical issue I've ever had was about 18 mos ago the SRS came on and stayed on. I had it analyzed at an indie I trust and they could not find anything - reset and the problem never came back. If it is something like a regulatator, will I be able to change it out easily as with a Bosch alternator?
Appreciate any wise guidance or thoughts you can share.
Cheers, Denny
