[C320-list] [C320-List] Electrical Problem

[Bruce Heyman]

Just to help with Fred's point after charging our batteries for 24 hours I
then checked each cell with a hydrometer.  Five of the Cells in battery
number two were in the green zone however one cell was very deep in the red
zone (almost off the chart).  When I tried to equalize the battery I found
that the five cells in the green zone bubbled but the cell deep in the red
zone did not.
While we can start the engine just on cell 2 it's voltage quickly drops to
11.75 with no load.
Time to buy new batteries.

Hi
Reading battery static voltage to determine state of charge can be
misleading. If one cell is down (more than 0.2 volts cell variation) the
battery is defective. Example: battery voltage 12.3v = 50% to 75% state of
charge OR one cell defective!
