Voltage drops ip and down

Ok, i assume it might be because i converted my car to carbed from TBI injection, i just cut out anything i did not have controlling something. I even removed the computer, the alternator did this a long time ago, then it died. I replaced it with a used one that flew apart on the inside so then bought a brand new one. Still been the same thing for a while, it will drop to 10-11 volts, then up to 14 for a bit, but tday it has gone down to 9 for a while, i dogged the car here and there, then it jumps up to 14 or so for a couple of minutes, but then bombs back down to 9 or so. Could this be my stock gauge acting gay or is there somethig to do with yanking the TBI system off???

Last night i went home and parked, this morning i leave for work and my fans are not comeing on and my windows wont roll down, the fuse for them was kina melted. I replaced it and still nothing. So, is the fact here i need to customize a harness???

Thanks guys,

Zane
