i have this strange kind of problem with my mitsubishi minica 2007. On half switch it does not shows battery on the panel. when engine starts it behaves fine. after the start when i increase the car's RPM above 2 my battery and hand brake lights starts being visible as generator is not working. i have checked the belt, battery terminals and reset the computer as well. but it was all in vein. can anyone tell me what is the main issue.
