Karl, 
12 .2 Volts is a 75% discharged battery.You'll need to check the battery celles with a hydrometer to see if your battery is worn out or not.
A healthy fully charged battery should rest at a min 12.65 Volts
True rested battery Voltage is no charging or dsicharging for 14 hours-then test.

Thanks to Frank Condelli, I now have a plug-in voltmeter plugged into the
cigarette lighter.

When I go to start the Westy, the voltage is consistently at 12.2V.� The van
usually starts right up, though occasionally, especially with hot engine,
the motor will drag.� Starter motor was rebuilt last year, BTW.

Is the 12.2 at rest normal?� It seems adequate.� Why the occasionally draggy
starter?� This has been a consistent problem with this van through several
starters, engines, transmissions, ignition switches, and sets of ignition
wires.� I know it will start after it's had a few minutes to cool, so it's
not a top priority job, but it is aggravating.
