1990 Honda Accord Warning light comes on when car is on

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.
