I remember reading years ago...somewhere...that after a vehicle is 5 years old, the electrical resistance begins to build up through corrosion of terminals, damaged wiring, shorts, etc. I recall something like 10% increase for every year after 5 years....does this make sense?

For instance: If you had a 100 amp alternator, after 6 years, due to decay of the vehicle's electrical system...you could only use about 90 amps? After 10 years 50 amps? I mean....It kinda makes sense, but....what do you guys think?
