Hi Guys,
I have one question that I would like all Sifus to give their valuable inputs. I currently have this problem which I don't have a clue on what the issue is.
Here it goes....
1) What should be the voltage reading at idling?
2) What should be the voltage reading when you switch on your air-con + head lamps?
3) Will the voltage drop when the air compressor kicks in?
My voltage is ~12+ v before I start my engine. After I start my engine, the voltage will increase to ~13 plus to ~14v (Remember that this is at idling). When I switch on my air con + head lamps, the voltage will drop to ~13v only. When air compressor kicks in, the voltage drops to ~12 plus v and sometimes, it dips below 12v at idling. When I press on the accelerator, the voltage increases again to ~13.9v (with air con + head lamps ON).
I actually changed a new altenator (APM, 75A) but the symptoms persist.
Is the above conditions normal during idling?
