Brera 1750Ti "false positive" warning lights
I have had electrical/wiring issues with my Brera. First the aircon/ventilation system stopped. The workshop advised it was a connection issue. There solution was "clean the connections". That worked but since then the car has been giving false warning light signals. eg. ABS, VSR, engine check etc. They come on when the car stops and the cooling fan cuts in. The shop says battery down, insufficient current to system. Sounds logical but the battery is fully charged.
Further, what is the battery specification for the Brera 1750Ti, I can't find any reference in the manual or online.
Any suggestions for the very best, strongest, most suitable battery?
