Can you please get a multimeter and take DC voltage measurements at the
battery terminals as follows?

1. Engine off.
2. Engine warmed up (like five minutes), idling.
3. Engine warmed up, idling, with headlights, interior heater blower, and
defogger on.

How many miles and years are on your car's alternator?

When you say "battery light," you do mean the warning light on the
dashboard, don't you? Please describe the color of this light and any symbol
appearing on it.

How many batteries has this alternator gone through? How many of these
batteries were permitted to die completely before replacement?

Please answer as best you can the questions people ask of you. Otherwise,
people are less likely to respond again.
