Car losing electrical power suddenly and comes back again.

[Asstragal]

Hi Everyone,

My car (Axio 2007) has this symptom where, the car's electrical power suddenly disconnects and comes back again. This happens in a frequency like once in two days. Totally random though. The power comes backs just in a second. So if this happens at night, all the lights would go off and comes back just in a second. Any idea why this happens ?

Thank you.

Both battery terminals are tight?

Ground wires to the body in engine compartment tight?

You might wanna check the alternator wiring and the ground connections on the car—those can get corroded or loose over time. Even if the alternator is showing good voltage, a bad connection somewhere can mess things up.
If that doesn’t solve it, you could try getting someone local to take a closer look. Sometimes you just need an expert to figure out what’s going on with the electrical system. There's this Ottawa electrician who helped me out once; they were great with troubleshooting stuff like this.
