Hi,
the starter connection that you photoed,
bottom side of the solenoid, is
for the ignition connection that triggers the
solenoid to run the starter. make a pigtail and
attach it to the female connector on the harness.
if you can you should heat shrink a cover over
the male/female connection, to keep it from
pulling apart from the vibration.
next, check the top connection for power only
in the start mode. lately i have gotten several
starters that did not supply intermittent positive
for the cold start circuit. i even sent a note to bosch
about this apparent change/difference but got no
responce.
lastly, the BIG ANSWER, most starters are be-
comming smaller and lighter and this is due to
newer magnet technology. magnets are now comprised
of ceramic instead of iron. if you wack the starter hard
enough on the casing it will crack the ceramic and
the field polarity will change. then the starter will either
not start or will drag slowly and draw high current
from the battery.
good luck
