 I think the old pumps grounded different than the later pumps  when my plane
was tested by Doug wheel he changed the grounding as I had it wired to the
later diagram. last summer I had a relay fail at 182hr...1993 kit   my bud at
the auto parts said my made in mexico relay was not so good even when new we
bench tested several different brands and there was a big difference in the
strength/sound when they engaged  I  went w/borg warner...did not have a bosh
to test but does seem to be a difference between brands. as soon as I finish
repairing my elevator push rod I will check my wiring out.
 happy trails
