So this is my 3rd cl-s. All have been 01's. This one is my biggest challenge yet. Everytime I turn around it's something. So here is the newest issue. When I hit about 6500 rpm the electrical power turns off but the motor stays running Radio, headlights, dash lights etc. Ran my own new ground wires today. Cleaned Al
And tightened all my power and ground leads. I can't figure this out. Anyone have any suggestions? PLEASE!!!!

 

how old is your alternator?

 

It's a month old

 

What about the ground to the under hood relay box?

 

Yes!! All of my ground and power. My background is in custom car stereos.so i absolutely crossed my t's and dotted my is with redoing my power and grounds. But now this mofo just took out my drivers side window switch and my sunroof switch. But the passenger side will roll up and down from the passenger side. Also when the power cut off this time the driver side window rolled itself up
