I have 2014 City with 65 W Headlights. I drive alot to my hometown from Islamabad. Due to bad lights of city, I changed 65W halogen lamps with 90 W Halogen (japanese). The electrician added a new relay and gave a direct feed to relays from Battery.
After 4 days of changing lamps, my 3 year old battery died suddenly on one morning and refuse to start the car. I have replaced it with New one of Same AGS battery. The problem is that during drive; when i accelerate the car, headlights starts to DIM and if i leave the throttle; it come back to strong light. what can be the issue, is it that 90W lamps are too much for city battery and wiring; or anything else.
