93 k1500 parasitic draw problems?
So I have a 93 k1500 I've put a brand new altenator and battery in and checked it today and I have a parasitic draw. I disconnected all my accessories/amp and subs, and pulled each fuse out 1 by 1 and there was still a draw can anyone tell me what else I can do to find what's killin my battery? It can sit for days and not die but when I start it and drive around my guage reads at 10/11 max and drops if I turn on the heat or headlights. Please help!

I agree - the alternator is bad. You can have it checked at Advance or Autozone but you can check it yourself. Let it idle with the heater on and pull off the negative cable. Goes dead, bad alternator.
Not sure I follow you on your question.
How are you checking this draw??? To accurately check for a drain, you hook a multimeter set to mA & you connect it in series on the ground side of the battery. I use a tool that connects to the battery & cable on the ground side, it has a knob you turn on & off to either connect the battery or to open the circuit. Your suppose to drive it, turn everything on. Then turn off the vehicle, connect the meter in series. Set it to mA & make sure the doors are closed, key is out of the ignition & wait til the interior light goes out, then you turn the knob to open the circuit, the meter should be connected in series & there will be currect flow through the meter. You set the range scale so you can watch for 0.03mA or lower. This is the acceptable amperage flow your suppose to have. Some vehicles it may take a few minutes for the modules to power down & go to sleep.
But if your gauge is dropping when you turn everything on, that is a problem with the alternator. Where did you get that alternator??? Autozone special??? I never will buy their electrical parts ever again, had too many problems with their crap. May have a bad gauge. Are the cables clean & tight??? No discoloring around the cable near the battery are they??? Means there is a resistance drop, cable is bad
After you pulled all of the fuses the only thing hooked to the battery would be the alternator.A bad diode or internal short to ground will cause parasitic drain.Sometimes this year of GM product had a problem with the digital clock staying on draining the battery.
