Greetings, What is the normal charging voltage for b16 engine? I already bought like 5 alternators but still the same problems, my voltage is fluctuating. It's like when I stepped on the gas, the light will go more brigthly it's like I switch my headlight to high beam but if it's idle the light will be dimmer as well as the park lights, radio, and etc. What should I do? What seems to be the problem?
