Hi,i got a problem with my car ford bantam rocam
engine,when i taking the terminals the car goes off
immediately,I've tried to replace new carbon
brushes but still the alternator doesn't supply the
voltage to the battery, I don't know wht to do please
NEVER Ever disconect the battery while the engine is running as this will damage the computer box. This is a specialized job. It could be the voltage regulater. The diodes in the aliterntor should be checked as well. It needs to go to an Auto Electrician.
