I read your reply and I have a few questions. What is an integrated control unit? What does it mean when
integrated is shorted? Where is the dash fuse box? What is an integral carbon pile? Where is the internal voltage regulator? The answer tells me that I should connect white/blue wire terminal to ground but what does the wire look like and where is the "ground"? Whenever I start the engine the battery warning light comes on. It also happens when I use the breaks. I'd appreciate it if you can answer these questions.

Hi ducvanphung, Thank you for the donation. The integrated control unit is a mini computer for controls or monitoring of various components such as 1. Wiper intermittent controls 2. Charge light indicators. and many more components. When it is shorted, it means one of the various circuits is faulty internally.

Internal voltage regulator in inside the alternator.

Ground is to any part of the engine, body or battery negtive terminal.

From the connector, look for a wire color that is White with a Blue stripe.
