Good points, thanks for making me remember that I installed a new alternator, rebuilt Delco from NAPA. I do not have a glove box light; yet.
I did check the brake lights this morning after I went out to see if the battery would take a charge. They did not appear to be on. I will remove the lens to see if they are just barely on and not bright enough to glow thru the lens.
Battery took over-night charge, the truck started, stock amp meter showed discharge; after 90 seconds at idle, the amp meter went to the center position. Battery showed 14.7vDC when I turned the truck off.
The truck does have a new wiring harness (M&H) that was installed during rebuild.
No radio, it does have electric wipers, a signal stat four-way flasher, headlights, cab interior light (I'll pull the cover off it and check the bulb element today also), chrome knobbed cigarette lighter and gas gauge for electrical circuit items. Pretty simple.
I will follow Jerry's suggestion with the ice-pick test light as the next move this morning.
The headlights on low beam are great. All four are NAPA halogen replacement units. When I switch to high-beam, the contacts on the switch kick out. I used a clamp on amp meter to check current on high beams, its above 18a! I am working thru installing "spike-edge" washers on each ground wire of each headlight and tail light. With taillights complete and one high-beam done, high current draw still exists. Looking at installing relay system for this issue if the rest of the grounding washers do not reduce current draw.
I will post results of the 'ice-pick' test as soon as I get all other checks completed. Thanks for advice and ideas for the draining issue so-far!!!
