I have a new to me 72 c10 the previous owner installed a big block. I went to start it today after sitting for a few days and the battery was dead after charging it I removed the neg cable to check with a test light for a drain. This showed a drain I one by one removed and checked all fuses still a drain . I removed the red wire from alternator--- bingo this is it-- I'm not sure if he wired it correctly when they installed the alt that is internally voltage regulated. Here are some pics. I'll check tomorrow to see if it is charging just wanted to see what you thought of the pics. The only wires used from factory plug is the red-- the white/blue is untouched as well as all the wires at the old external regulator. Any ideas?
