First thing, check all the fuses and fusible links for continuity.
Put the car battery on a battery charger overnight and see if the new
battery was sold to you run down - if the new battery sat on the shelf
for more than a month, it may have been low on charge when installed.
Then get a decent digital voltmeter and see what the battery voltage
at the terminal posts is at rest (engine off, doors closed, no load),
during cranking, and while running.
You should get 12.6 to 13 volts at rest, 12 to 12.5 with the
ignition on but not starting yet, and it shouldn't drop much below 10
volts while cranking the engine over, at least for the first few
Once the engine starts the voltage at the battery should pop up to
between 13 and 14 volts, and with the engine above 2000 RPM it should
be between 13.5 and 15 volts depending on the outside temperature.
13.8 to 14.5 volts is the ideal for float charging a 12V lead-acid
If you are outside the normal range on any of these voltage
readings, tell us and we can narrow it down.
