Hey I need some help yesterday on my way home my battery light was coming on and off at speeds above about 50 km/h tgis was cuasing my car to bog out and try and stall I got a new battery thinking that would be the issue and later after hooking it up my head lights will come on but it won’t turn on my dash lights or radio and won’t crank at all I’ve checked fuses and nothing I started it this morning with the old battery to pull into my shop so I tired putting the old battery back in and same results headlights on but nothing else I am wondering what my issue you could be maybe a faulty ground wire I’m not sure maybe try replacing my battery terminal clamps
