<VV> Measure Voltage Drop (main fuse question)

[NicolCS at aol.com]

II doubt that you will see even a tenth of a volt at full current and I  feel 
that we do need protection.  In fact, I'll go and check  the voltage drop at 
Imax on my '66 and report back.  Why add  one?  Our cars were built to provide 
5 years of service, give or take and  we (like B-52s) are at many multiples 
of the design-life.  Things wear,  chafe, and degrade and we have (in most all 
Corvairs) unfused B+ running all  over the car.  Poor repairs (on a 
Corvair??), corrosion, and shoddy parts  lurk. Most people don't have a clue as to how 
to repair or modify wiring  properly.  Why not protect the investment with a 
$15 mod?  Many  customers have brought in expensive cars that nearly met their 
demise through  wiring fires.  Also, insurance companies sometimes view a 
wiring fire as  "poor maintenance" and will deny loss claims. So, every car that 
gets  wiring repair in my shop gets a Maxifuse.  I don't see any significant  
downside.  Manufacturers have been fusing the B+ for over 35 years.

<snip>A few tenths on a 12v system is more than I'd like to see,  especially 
since 
incandescent bulbs, like the headlights, have a brightness  proportional to 
the 
3.5 power of the voltage. 
So, the real question is,  why add something that does this, and you don't  
need?<unsnip>
