When engines is started, pointer may stay is this area
temporarily but should gradually rise above 13.3 as
generator reaches normal output.
The pointer might remain in this position temporarily
when the engine has boon stopped after considerable
use, due to a "surface charge' in the battery. To get
a correct reading, turn an headlights for a few minutes.
