Oh, the horror...
started today with truck off and a battery voltage test....12.1V. i forgot to put it on a charger last night!
with the low beam lit the voltage was.....
negative side....11.5v
EDIT:
positive....12.1v-9.6v=2.5v
negative...12.1v-11.5v=.6v
2.5v+.6v=3.1v total voltage drop on this circuit....with what we are working with here
12.1v-3.1v=9v
the bulb is seeing 9 Volts in this example..
and again....michael hurd corrected me and directed me to the proper way to do this voltage drop test.
