Battery or alternator

[willvill2]

The headlights are a big drain, bro.(delta of 1.3V).... From the normal 55/60W,- did you upgrade to 100W or higher? But then again, you said you upgraded it a year ago.

It looks like you need to have your alternator checked...

I will start with my battery. I'll have it tested black and blue. I upgraded to 100w.
