85 olds intermittent rpm-headlight-etc prob.

85 olds regency brougham (sp?) 205K miles V6 auto fwd. Have an intermittent problem -- while driving or idling engine rpm will drop and come back, at the same time the headlights will dim and back, dashlights same, blower motor same. Need new blower motor, but that problem comes at a completely different time. Everything is ok tune up wise. Trying not to put a lot of cash in due to miles. [Electrical is not my thing]

Alternator. My '92 Regency had the same problem. I replaced the alternator, problem fixed. I paid about $82.00 my cost for a GM alternator.

Thanks a bunch. Thats what I thought it was and have the receipt for a free replacement from O'reillys. Thought I would give this forum a shot before I went ahead and switched it out. Thanks again
