I have an old 4awg kit. What do I need to assure plenty of clean power? Larger than 100 amp inline fuse? Do I really need another batt or cap? I'm a bit of a beginner, thanks |

I'll need to disassemble some stuff but it's seems like a need now. I've got a new heavy duty battery but the alternator I was afraid of, If I clean up the wirung it might be ok. I'll end up getting a 2 farad cap before an alternator. Thanks |
