Put a voltmeter on the batt posts and take a reading with nothing but
the dome light on, it should be over 12.5V.
Then turn on the headlights only and see if the reading drops below 12V,
it should not drop too much, maybe 12.0.
Then turn off the headlights, and crank the starter and see if the
reading drops well below 12V, it should not go below 11.5V.
This should prove the battery condition, or the starter shorted if the
voltage drops sharply.
