- I have an Sidecik 97, w Automatic Gear.

-Fact: The Battery is v.close to End (Significant Voltage drop, while turning-on the Lights. But its Ignition is perfect!).

- My Quastions: Could a Low Voltage somehow Damage the Computer,or other Electronic Sensitive Devices?
What about the Alternator - Could it be Damaged?.
Shouldn't there be an Azard - "low Battery" ?.

measure your battery voltage with a digital volt mater, DMM.
report battery voltage when running and when not running.
report here.

12.65v , resting for 4 hours, = good. (key off reading)

14.7 v while running shows alternator is working. all that ROOM TEMP.

your computer is not that smart. ( Maybe on a Lexus)

most computers (ECU) just get stupid at below 10vdc.
the power supply just shuts down , harmless.

there you go. good luck
