Electrical System problem #1

I pulled my battery to charge it and now I'm getting a wheel lock alarm which will not allow my car to start. It is in my drive way same as when I last used it. It ran fine prior to charging my battery.

Wiring problem #2

Was replacing h7 headlamps and discovered all of the insulation on the wiring inside both headlight assemblies had disintegrated and both assemblies contained multiple bare wires. This could result in a short or blowing a fuse when driving making headlamps stop working. Could easily cause an accident. Or car could catch on fire due to short circuit. I have googled this and found many many similar complaints. A recall should have already been voluntary on BMW USA or forced by the ntsb. Extremely dangerous situation.
