I am stuck with a problem with the 12 v battery in my Peugeot Ion 2013 (I think, maybe 2012) that I can't fix. I really hope that you guys can help me out.
I am a total rookie in terms of cars both electric and ICE, but I will try to describe the history of the issue as well as I can.
Two/three weeks ago the red battery signal started showing. This came after a period where the car had been used less, then usual because of the Corona stuff, but had been used at least once a week. Then a couple of days later the yellow alarm signal started showing. Then a couple of days later everything in the car started blinking and it stopped just before I could get it to the garage.
I got towed to the garage and thay said that the problem was that the car wouldn't charge the 12 v battery. But didn't know how to fix it.
I then found a guy who knew a lot about the Ion/Imiew/C-zero. He took the relay from the fog lights and changed it with the one for the 12 v battery ( I am not exactly sure what it is called). Then the car charged the 12 v battery. But the red and yellow alarms were still showing. He removed the minus thing from the 12 v for 15 minutes and the alarms stopped showing, but the next day thay were back.
He couldn't figure out why but told me to change the 12 v battery and see if that would make a difference. I changed it but while changing it me and my friend noticed that it made a little zapping sound and some relays were clicking, when we connected the minus pole. My friend said that that was bad because it meant that somewhere in the car something was using power and that was draining the car, but the Imiew/C-zero/Ion-guy said that all cars have current in the background for alarms and stuff. Well anyways it worked. I drove for a while with no alarms in the dashboard and again later in the evening. I also checked with a multimeter. The battery said 12,5 when the car was off, but 14,3 when I turned it on, which meant that the car was charging the 12 v battery
BUT the next morning the alarms were back. I don't know what to do. I am going to take it to a garage as soon as possible so that they can read the alarm codes. But I am afraid that they won't know what to do either. I also dont know what to do with the car in the meantime. Is it okay I let it just stand in the street if its draning the 12 v battery?
