So I recently took my car into the shop to have the fenders shaved and new fenders put on so I can fit wider tires. The car came back with the battery indicator light on. SO my best assumption is that a wire was cut during the shaving process.
The car runs fine if it has jump leads connected to another car but once I remove the leads after about a minute later (when the juice runs out in the battery) the car shuts off. I assumed this was an alternator problem but after replacing that with a brand new one the issue was still occurring. So I replaced the battery, but the battery indicator light is still on so no/not enough power is getting from the alternator to the battery. Ive contacted the shop that did the work complaining that they must have down something but they are refusing to help.
So what I thought about doing (as a temporary solution) was to run a large cable between the alternator and the battery. Is this be just a completely ridiculous idea that's going to short out my system or could this be a temporary solution. If it is a solution, should I put some kind of fuses between them or not? I am fairly uneducated when it comes to the electronics in a car so any help would be much appreciated.
Thank you,
Keon
