Motor is back in the car but I'm getting low voltage. I disconnected the "octopus" and carefully labeled every connection except the ground strap attaching point on the DS near the air box, because my brain said "oh, it will be obvious where it connects." It was not obvious. 🙄

Any help? I've got it run to the motor mount, but wanting to double check while I'm cleaning and reattaching ground wires. I'm hoping that's the cause rather than a bad alternator.

 

There is a bolt at the right side frame rail - 2 or 3 inches in front of the strut tower.

 

I know about the stud on the right side. I'm asking about on the Driver Side (Left Side in US).

There's a corresponding stud but it doesn't look like I've ever loosened that nut, and I don't think the cable would reach that far...

 

That stud mounts an A/C line bracket.
The stud you're looking for is just to the right (looking in from the left side) on the strut tower.

 

Welp, that wasn't it either...

For the sake of those who might make this same mistake in the future, here's the wire I'm talking about.


Remember kids, there are TWO wires that attach to the big post on the starter. Apparently your car will run without one being connected, but it's running on your battery. 🙄

 

Yep its that one.

Would have been nice if they were wire tied together. 🙄

 

Yes i know i have changed the starter on my r52 twice. I cleaned the ground points when i rebuilt the bottom side of my car, its was really corroded with age. Also I cleaned all the ground points to battery and the body grounds. Replaced the alternator with a lifetime bosch unit. Also changed the switch for the ignition, it was starting to stick. Car starts up so fast with almost 300K miles.
