I am trying to adjust the on/off ratio on my 88 300E. Iwas using a dwell meter as other people have done. I connected the positive side of the dwell meter on pin#3 of the diagnostic connector on the driver's side fender, and the negative side to a good chassis ground. According to the manual I should be getting between 21-27 degrees for a 35% to 45% duty cycle. I get nothing, no indication at all! The needle on my dweel meter does not move at all. Am I missing something here?
Thanks for any help.
