[ICOM] IC-2100 fused ground wire

[paul at w8aef.com]

It is protection for the radio's return power lead.  As a for-instance: 
without the fuse in the return lead, and the lead from the negative battery 
terminal to the chassis were to fail, the automobile could possibly use the 
antenna shield (grounded to the chassis at the antenna), radio, and radio 
negative lead for it's ground.

A real gosh darn-it, and it has happened.
