2 weeks I was driving home and my ABS break.

2 weeks I was driving home and my ABS break light went on. As I turned off the freeway the power steering went out. I parked in a gas station to turn it off and on and it just died. Got it jumped and made it about 2 miles before it completely died again.

spoke to multiple mechanics and was told it was the alternator. My brother replaced the alternator but damaged the pigtail that plugs into the alternator in the process. He put silicone on it to keep it connected.

i drove from long beach to la last night and woke up this morning to go to work and the battery light was on again.

battery is a month old and it was 100% charged as of yesterday.
alternator is rebuilt and was just bought 2 weeks ago.

i did get in an accident in october where I rear-ended another car but the only damage was to the body of my car.

what do you think the problem is? And if it is the pigtail, where do I find a new one?

pleeeeeease help : )
