Infamous molex group/part numbers
Posted: Thu Sep 24, 2020 9:28 pm
The infamous molex on the engine shroud, source of many alternator/charging problems, has struck again and I need to rebuild it. It wasn't the red wire that broke, but the male quick-disconnect itself. The molex is looking cracked and brittle, so I'm going to replace it and change the connectors on all six wires.
SAV says the outer molex (with the male quick-disconnects) is group # 09-50-03, though this doesn't match the parts catalog drawing. EI says the connector is 09-50-06, which does match the parts catalog. Looks like SAV has 09-50-03 and 09-50-06 reversed?
The parts catalog says the outer molex is AMP 180 904, which is Mouser # 571-180904, but the Mouser drawing for that shows the inner molex.
Similarly, the parts catalog says AMP 180 906 for the inner molex, which is Mouser # 571-180906, but the Mouser drawing shows the outer molex.
What a confused mess! If I order both inner and outer connectors, from either SAV or Mouser, then I should get what I need, regardless of what they're numbered.
But what about the quick-disconnects? More confusion. The parts catalog shows all sort of connectors but gives no indication of what matches what, and which quick-disconnects fit which housings.
09-50-11 looks like the right male connector, and it's listed as AMP 180409-2, Mouser # 571-180409-2, which SAV calls "4qmm", and that looks to be right.
But what about the matching female connector? It's likely 09-50-12, which looks right in the parts catalog drawing, but is described as "Flat plug housing" which it clearly isn't. They give a Bosch part # 1 351 355 810 which only matches some housings (on Mouser), not a connector.
Arrgh!
Can anyone tell me which female quick-disconnects I need? The outer molex is not looking good, and neither are the male quick-disconnects, so it seems like a good idea to replace the inner one as well since they're likely also sad, but this whole part # fiasco is giving me a pain.
