Question about 1985 Chevrolet C1500
How about if you disconnect the battery negative, disconnect the main power lead from the alternator, insulate it and tuck it safely away, and then reconnect the battery negative. Is the draw still there? If not then I would say the diodes in the alternator are at fault.
Very best regards
