VOLTAGE SPIKES and DROPS
I have a 2006 EVO RS... About a month ago I started noticing that my voltage will drop to about 10 on my gauge and then 14 when I give it some gas. I replaced the battery as well as the starter syliniod and it is still doing the same darn thing. Cant figure it out.. Also I am throwing a couple codes lately as well.
Current Fault Log
------------------
P0137: O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)
Pending Fault Log
------------------
P0137: O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)
Historic Fault Log
------------------
ECU reports no historic faults
Other discovered fault codes
(possibly pending, current or manufacturer specific)
----------------------------------------------------
P0622: Generator Field "F" Terminal Control Circuit
End of report.
It is really getting annoying to be driving down the road and seeing my lights start to dim at times then spike back up for a bit then die back down...
Anyone have any ideas.

Alt turned out fine
Alternator checks out to be ok.. Belt seems fine.. I changed the ground cable on my battery as well because the old one was all eaten and corrodided and stuff.. Figured that could have been my starting issues... That didnt work so when I changed the starter I figured that would be the starting issuess I was having, it started but the voltage was low.. Checked the battery and it was reading low so I bought a new one. Now the car cranks however the darn thing will cruise for a bit at 14 volts and then start dieing to about 12... If I turn on the A/C it drops lower, When I turn on the windshield wipers I can see the voltage drop everytime the wipers start to wipe.
