My sister and her bf moved in with us and are constantly using our car to jump start their own car (and I mean almost every day, sometimes more than once) and ever since then our lights have been flickering and now our car hesitates to start… I’m trying to figure out if this is because of the jumping or because of something else.
It’s been like a month and a bit of this.
Please any help is appreciated!
No, it’s not good for your battery or your alternator, and there’s always a very small risk that it can fry the computers in your car due to voltage spikes when hooking up and detaching the jumper cables. That doesn’t happen very often, but it’s also not a no-risk situation. Tell them to get it fixed or take full responsibility for anything that happens to your vehicle.
