electrical grimlins/pulsating lights

My 92 has been experiencing power surges. The lights, exterior and interior, pulsate. This is not related to the heater grid since it happens constantly and even in 90 degree plus temps. I have added ground straps from the engine to frame & body but with no success. The volt guage varies from 11 to 12.5. I have been getting an engine fault code of 12-46-55 occassionally and more consistantly lately. The manual says that's high voltage at the battery. My question is: is this the alternator or something else? NAPA wants $125 for a rebuild. What can I do to narrow down my problem? Any ideas out there? Thanks guys.
