Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hey there, when the brake and battery light come on simultaneously this indicates a charging issue.
Do you have a volt meter so we can check to see if the alternator is charging properly?
since I never heard back from you on whether or not you can test, my best assumption here is a bad alternator.
If you need anything else let me know, if not just be sure to leave a kind rating so the site credits me for my time.
