Did you clean the terminals and put it back on tight?
There should be 5 wires going to the alternator
"B" .. One goes from battery to alternator ... charges battery (charging voltage)
"IG" .. Another goes from the ignition to alternator to charge up the field coils so the alternator can develop charge to feed the battery (12 volts)
"L" .. Another goes from the PCM to the alternator and determines if the dash warning battery light goes on or not (12 volts)
"C" .. Another goes from the PCM to the alternator to determine charge mode (PCM volt out, pulled lo then lo charge mode; pulled hi then hi charge mode)
"FR" .. Another goes from the PCM to the alternator to adjust engine idle speed (PCM volt out, pulled lo then hi idle; pulled hi then lo idle)

the wire came unhooked while running and I think it shorted out on something and I noticed the battery light came on so I killed it noticed the wire lose hooked it back up started the car back up and now it runs like this

I would think that shutting off the engine before re-attaching the wire should just return the engine to the previous state (running well)??
Should read codes. And get as much information as possible.
Many of the wires goes to the PCM. Maybe it needs a reset??
Take the battery cable off for ten minutes and then reattach??
It should reset the PCM and turn off the CEL??
Or use scanner and reset the PCM??
Hopefully, it will return to normal.
