Question Battery charge light will not turn off

I am having really big trouble with my 1991 Honda Prelude and it's getting to the point where I am starting to feel like I want to get it towed to the wreckers. I don't really want to do that but it's really taking the cake.

I hosed down my engine bay and the battery warning light came on and then an hour later my battery went flat. So far, this is what I have done to try and fix the problem:

- Checked the alternator fuses
- Fully charged the battery
- Replaced the alternator with a remanufactured unit
- Replaced the crankshaft pulley
- Replaced the drive belt


Today I checked the replacement alternators' B terminal with a multimeter and it's reporting just 3.84 volts! I thought perhaps the belt was slipping so I tightened it but it made no difference.

The only thing that I haven't checked is the air conditioner compressor pulley.

This could be a hint but it could also mean nothing... when I first installed the replacement alternator, the battery charge light no longer came on but the drive belt was squealing really loud. Then half an hour later, the squealing stopped and the battery charge light came back on again and has been on ever since.

What do others think?
