Hi folks, was doing my mate a favour and changing his starter motor for him on his 2011 1.8tdci transit connect. All was going well, got the bolts loose no problem on the starter mount, went to loosen off the power connector nuts and got the two 12mm ones loose nice and easy, got to the 10mm and the starter motor housing shattered as I went to turn the nut. That left us with the issue of how am I removing the nut, and after a couple attempts of removing while it was still on the starter, it was clear it wasn't coming loose. Decided the only solution left was cut the nut with the Dremel. All was going well, was about half way through, and disaster struck, the connector plate from the loom snapped and now we can't connect the 10mm post of the starter.
Question is, are we now having to replace the looms from positive and negative, or is there a way to do it without having to completely replace the looms? The plastic housing isn't in great shape, it took a bit of a beating while I was trying to get the connector free, but it should still be usable and keep everything covered.
Pics of the current situation are attached.
Also, side note, is there meant to be a connector on all three posts? I don't remember any connectors on the upper left as you look at it, and the plastic housing only appears to have to upper right and the lower (10mm) connectors.
