Peugeot 206 Battery Light Glows

Have a nice day ,

I have a 2001 model Peugeot 206 Petrol-LPG vehicle. Two months ago, my display had a malfunction on the LCD panel, I sent it for repair, my indicator was repaired through a familiar master in Konya. I said let me show you. Although I told the master that there was no indication, he directly disconnected the charger, he changed the diode tray. I managed it with a battery reinforcement until the indicator came on. The indicator came on, everything worked fine, I started the vehicle, the battery light turns red. I separated the cable going to the panel, I connected the lamp together, I connected the other end to the fuse of the contact. I was unable to figure out exactly what the problem was caused by. I would be happy if you can give an idea or help about this malfunction.

Thank you so much.

brother battery I will fight with the masters for 1.5 years, finally I put it in another battery, it did the same with it.
