John,

Just about every GM factory service manual from 1975-80 has the HEI test procedure; do 
you know someone with a copy?  The only copy I can make is a photocopy as I don't have 
a scanner, but if need be I can do so and drop it in the mailbox.

putting out the proper amount of voltage...Is there a test I can do..??....I've looked 
for a website that could show me but have had no luck.....Thanx...........John
