More important is the power supply equipment. Find that and look for the Meter installation. That’s the only way to guess how soon it might get lit up. A meter in means the utility side is done. Especially, if the meter display is on.
The meter socket is in a white refrigerator-sized box roughly in the opposite corner of the first floor from the cabinets. You see it on your left when you go in the 1st floor parking entrance next to Orvis. You can see it in the first attachment of post 36.
You have no choice but to go up the ramp to the second level as you enter the parking garage. The chargers are exactly behind you as you come up the ramp, heading east, so you won't see them until you turn left or right and look west.
found them on Google street view. This is from the I-43 exit for N. Port Washington Rd. You can see the Superchargers on the 2nd level above the entrance for the 2nd and 3rd Level parking. I was needing a charge while driving by last weekend, but wasn't sure where this was located. Stopped at Oak Creek with only 3% SOC. Will definitely try this in the future.
