[QUOTE="metalheadjoe, post: 8814275, member: 581422"] Play a test tone at night with headlights on. If the headlights dim and stay dim throughout the tone, you need more alternator. If your headlights dim at first then brighten while still playing the tone, you need more battery. What does your stock alternator put out, and why do you think you need more electrical power?
