Weird Electrical Issue

I noticed that my radio rebooted a couple times when I was heading to work the other day. I didn't think much of it cuz it didn't happen later that day or days to come. When I was parking my car tonight I noticed that my lights started to dim while turning my steering wheel to pull into a spot. Once I was parked I rotated the wheel all the way to the right and to the left. I noticed that in several spots that the lights would dim or go completely out. The worst was when all the way to the left. Every time I would bump the far left spot the radio would reboot and lights would dim.

I wondered if it was just a fluke thing so I turned the car off and tried to turn it back on but nothing. No click or anything but all other electronics worked. I tried moving the wheel into different positions to see if it had any effect on the car starting. I didn't matter. At this time I was thinking maybe the steering column was bumping into the ground wire for the starter and figured I would have to try and look at it in the morning as it was dark out.

Before I went in for the night I decided to take a look at the battery connection just for the heck of it. The connections seemed fine but my capacitor for my sound system was flashing 0 volts which I found strange. I disconnected the battery and reconnected it but the cap still read 0 volts. I checked the ground on the cap and noticed it was a little loose. I tightened this up and the cap started to show the correct voltage of the battery.

Thinking all of this was very strange I decided to try to start the car again. To my surprise the car stared right up without a problem. I went back to moving the steering wheel around to see if there was still a problem with the lights dimming and radio rebooting. Nothing had changed. Still acts like there is a bad ground or the electronic steering is putting to much strain on the battery. Before I start troubleshooting further in the morning I figured I would check and see if anyone had any thoughts on what may be going on.

With car running the voltage is usually around 14.4V which means the alternator should be fine. Reading on the Cap with the car off shows the battery at 12.2V

Maybe you should get your battery tested for output current. Even if it has proper voltage reading.

Make sure the terminals on your battery are snug

Well I checked things out and couldn't find anything more than the bad ground on the cap. I took some sandpaper and cleaned up the area and then made sure everything was snug. I then used my phone to take video of the voltage readings while I turned the wheel. The voltage would jump up to 15.1V while turning the wheel and the radio never rebooted. I didn't get a chance to test at night to see if the dimming of the lights still occurred or not. As of now I think that may have been the problem but its all a little strange.
