Hey Scotty I have 2003 Honda CR-V ex with 225000 miles on it!!! I bought the car 2 years ago and since then I’ve put 4 alternator in it and the last one placed was a denso but the lights are starting to pulse and it was put in a month ago also when I turn on my headlights or air conditioner I lose up to 300 rpm and my engine starts to rattle on the belt drive side !!! I want to keep the car but I’ve almost paid in repairs what I bought the car for what should I do?
Check your AC compressor for a malfunctioning clutch and a loose alternator belt.
Check the ground for the alternator. If it is fine, you may have issues with the car computer.
