Alternator started sparking

The relay worked for the most part. It’s charging at a constant 14.2 and no drop between the alternator and battery. When I put on my headlights though, there’s a sizable overall amp drop and there’s an additional drop from alternator to battery of .30. It’s a great step. I only had an hour to mess around tonight, but tomorrow I’ll have the whole day to work on it. The front marker light is out and I’m assuming it’s the cause. I’ll find out tomorrow. Thanks again y’all!
