I'm sorry to have to ask this...

I'm sorry to have to ask this because it's something probably everyone knows except me.

What's the small torpedo like thing on the bottom of the voltage regulator? I recently replaced my regulator and the "new" one doesn't have one. Is it needed? What does it do?

It is a noise filter to keep static off the radio.
The old (original) regulators had points in them that caused noise but the new solid state ones don't need this.

Outstanding! That's exactly what I needed to know! Thanks TF!
