the reason i am changing the alternator is that in night time when headlamps on high bright/full beams and ac turned with fan on 4 mean full blast then my horn sound goes half comparing to day i had installed original bosch horns with honda accord's relay says 45amps and 60 amps battery is installed in my car and 35amps alternator output on full load tested with DMM. sorry for the late reply i was busy in some projects. share the best grounding points so i can do it myself instead of going to electrician mostly in my area no one knows what improved grounding is.
