First Drive

I modified the indicator for the warning light panel to use some of the indicators for the error lights and run indicators that come from the drive. While I had the soldering iron out I wired up the isolated DC/DC to the amp hour meter.
I pulled wires to the interior for indicators, meters and switches.
After a glitch with the programming of the watt hour meter, I got it reading correctly, I dropped the car off the stands and moved it under electric power for the first time but I only went 15 feet.

 I checked the brakes, as the car had not been on the road for a long time. The rotors were pretty rusty and I may have to address some sticky calipers. The front tires are rubbing the spring mounts and I added 5mm spacers for now, I will get the proper tires in the future.
I aired up the tires and install lugnuts, each wheel only had 3 when I purchased the car.

I decided to not complete the dash and give it a test drive, I found a few issues, the tachometer was acting a bit strange, I decided to remove a few reflectors and drop the pulse input to the controller per recommendation of controller instructions. I reprogrammed the controller and changed the ramp and rpm limit. 
The tach was still intermittent, I finally realized that driving with the hood off was causing improper reading from the optical tachometer pickup.
I have a few issues with the brakes, as well as the the speedometer cable is causing a fluctuation in speed.
I did a quick acceleration test and it will burn the tires and accelerate pretty well, I saw 700 amps at one point, but the batteries were not fully charged.
After the test drive I dressed the wires under the hood and secured things. I cut the acrylic sheet and drilled and mounted it over the front batteries.  The electric vehicle stickers were installed as well.
The hoses for the cooling are connected, but I haven't filled the system or connected the pump. During all the testing the controller barely got warm and the fans came on for a little bit.
