Hello everyone. I have a JDM 1995 Impreza STI (95,000 km on the engine), and I have been experiencing a little trouble with it lately. The voltage meter next to my boost gauge fluctuates occasionally, causing my headlights to brighten and dim while I am driving, but it doesn't happen all the time. Also there is occasionally a squealing sound when I first start my car, and will occur when I am idling the engine at a stoplight, or driving in the lower RPMs, but will go away at higher RPMs. Would this indicate a bad alternator, or something else? Can an alternator alone cause this squealing? Would the belt cause the voltage fluctuations? Thanks!
