Ok well this is how it started. I moved my battery to the trunk then did a fuse box relocation. Drove it for about a week. No problems. I was driving and the car cut off like it had a bad alternator. Jumpy rpms. Then power cut off. Pulled off to the side of the highway. Figured I was going to have to swap the alternator right there. But I decided to to hack into my harness and see if that was the problem. Found one of my alternator wires for the connector was falling apart from where I had to shorten the harness. So I reconnected that. Someone was nice enough to stop and give me a jump. So once my yellow top was charged up the car fired right up. Instead of running an inline fuse for my battery wire I'm using a100 amp breaker. Well the car will start up. Then after about 30 to 45 seconds of driving I can feel the breaker tripping because the car cuts out for a second and then it drives fine just under the load from the alternator. I tore apart my interior to see if maybe my power cable was grounding, but its not. And to my understanding if it was grounding it would trip the breaker right away instead of after driving. Only does it under load and doesn't trip at idle. So some how I'm getting to much amperage sent to my battery causing the breaker to trip. I'm thinking bad alternator possibly?
