That's a good idea that I have done also, but it is 1.4v drop, not
.7v

A competitor of ours wired a cement truck with a new Kenwood right to
the battery with both leads (not fusing the negative lead). It lost the
chassis ground, and the starter current went through the radio back to
the battery. The radio was toast (literally). Joe M.

I think we all agree that there's nothing wrong with having the fuses
there.
With that said, and we want to install fuses in the grounds of existing
radios without the fuses, is there a favorite fuse holder for in-line
use? I've
My bet would be that the black wire fuse is there for positive ground
vehicles, a vestige of times past. In that case, the black (negative) wire
is hot, and you would need the fuse there.

That is one reason, but the other is for the times you go directly to the

Budd, two fuses at the battery will pervert a car/truck fire if the ground
wire comes in contact with hot wire of if the hot wire comes in contact with
a ground. A diode will prevent frying the radio if the polarity gets
switched.

Yup, **That** sounds about right. ;-))
Suppose that dual-fuse has some validity -- *IF* you're in the habit of

Some Mobile radio power cords are fused on only the positive line.
Others are fused on both lines.
One's logic is you only need one fuse. The other maintains their

Nope. Kenwood is a big promoter of fusing the negative lead. The reasons
have already been mentioned on the list. Most, if not all of their
radios, do not support traditional positive ground. I say traditional
because there are now positive to negative ground converters for use to
install negative

with the 0.7v drop,and its idiot proof ! Of course,fuse

Hi budd
Yes,0.7 volts per side,1.4 total. Some radios wont like it but most I
have tried worked ok. 73,Lee
