Thread: Do I need a new alternator?

yeah 2 or alt guage , also something i did that helped out temendously was make a 4 ga wire with ring terminals on the end and route it off the back of the alternator to the battery and keep the factory wire on there also . For the power problem second battery is always the better route , ive got a optima yellow on mine and my headlights dim a little but not bad at all

The battery would only help once the car reaches the voltage the battery is putting out. By that logic, you're already dimming by the time the battery is doing anything at all besides getting a charge.
