So passing on the ranger to the youngest kid; it's had it's share of electrical issues; but lately seems pretty stable.
So this weekend we swapped out the radio for an upgrade; everything seems fine. Drive around the next day, still good, so he goes to school today, started fine this morning; but battery was dead after school, jump started just fine; then it was dead again after practice (4hrs later); again jump, drive home.
I go out to look it over, figure he left the headlights on or something stupid; nothing obvious, go to start it (5 min after driving) and it's dead, ~9.5V, battery is only like 3-4 months old
So I put the meter into Amps, and key out, doors closed, lights off I'm seeing a .33 - .5A draw (it switches back & forth but stays on .5 most of the time)
I assume the computers need some power, but that much? With the door open (dome light on) it draws ~2.5A
Disconnected the radio completely (well removed the cable harness from the back of the radio) and its still drawing .5A
Before just pulling random fuses, any suggestions where to start?
Running its reading 14.5V, so Alt should be good
