I disagree my Presidential Friend. Though each item follows a different set of parameters, when it comes to the charging system as a whole, any one weaken or aged component can effect the integrity of the system. When these parts go on sale, I scoop up two or more each time. My cars are all on different maintenance schedules as they receive different amounts of use.
I bought PINKIN December 26, 2006 with 19,100 miles on the odometer. I took it out a month ago (January 26, 2012) for a maintenance drive and parked it with 24,319 miles on the odometer. Over the last five years I've replaced the air filter and oil filter and the battery twice, yet the fuel filter and the distributor cap and the ignition coil and control module and the voltage regulator were all installed in Wixom, MI on April 29, 1986.
I bought my 1990 OldSchool1 in 1992 (Wow I just realized that was 20 years ago). Today, it's my daily driver. I cannot think of a bolt on this car that hasn't been removed
At 140,000+ miles I've lost count of the number of times I've replaced the wear items, yet they get replaced on or before schedule. For Mark VIIs, a 36 month old battery is an old battery and taxes the rest of the components in the system including the accessories.
So unless a Mark VII is driven and garaged like PINKIN (5000 miles in 6 years) then I'd suggest including everything listed above as a tune up item
