When voltmeter pointer stays below 13.3 with the engine running fast enough to operate
the alternator, it shows that the alternator is not operating or voltage regulator is out of
adjustment, or that current being drawn from battery by lights, heater fan, or accessories
exceeds alternator output.
When engine is started, pointer may stay in this area temporarily but should gradually rise
above 13.3 as alternator reaches normal output.
