FYI
Paul, sorry but I disagree.
For HF mobile installation, GM and others recommend that the radio NOT be
grounded in the cabin. Both battery leads should be fused at the battery. The
reason for the negitive side fuse is in the event that the battery ground lead
to the engine block should go open or have a high resistance there will be very
high current trying to find ground when you start the engine. Starter motor
current can be in the hundreds of amps. You do NOT want that amount of current
flowing thru your rig!

<home-run to the battery posts. If the negative fuse blows and the positive
<fuse remains closed -- and *if* the radio chassis is common to negative
<power with grounded connectors (e.g., SO-239) via a ground return through
<the vehicle chassis, then the coax braid and other supplemental grounded
<leads on the radio chassis will carry the full rig current.
<Seems like in all cases where the rig chassis is common to the negative
<power lead, the negative lead wiring should go un-fused at or very close to
<the negative battery post.
