Anything in that range will adjust. The way you
3.9 is low as well.
Measure the outer two pins to make sure your getting
close to 5V.
Before getting a new one, run the old one back and
forth a few dozen times with the engine off, then
measure again. Also make sure the connector is clean
and free of crudbunnies.
