Bentley: 100-13, Figure 9, the closest ground.

So ya, I was cleaning the engine grounds on my M30 and I over torqued the smaller one and snapped the bolt in half. I nearly sh*t. I couldn't screw the nut back on so I flipped it upside down where the threads are closer and was able to tighten it down on the broken bolt.

Anybody think that'll be a problem? Does the wider surface area of the bottom of the nut somehow help to ground the circuit?

I'm really hoping I don't have to replace that whole ground module thingy because of one crap bolt...

Pictures please. Wider surface area won't make that much difference as long as there is good contact.
