Friday the Alternator died in my little brother's 96 Civic DX. I took it to the Autoparts store and had them test it and it failed so we purchased a new one. I installed it and started the Civic but it is not charging the battery just starts discharging slowly as it idles. I have removed the new alternator and had it tested where it passed all the tests so the Alternator is supposed to be good.
Now the other weird thing is that his battery light did not and still has not come on. I pulled the instrument cluster and tested the light and it is good but it doesn't come on with the rest of the warning lights turn on when you first turn the ignition on.
I have also checked Fuse 15 and the fuse is good (tested with the continuity tested on my multimeter) and the fuse box reads battery voltage when the ignition is turned on so there is power there.
I also checked the main wire in the alternator and the mutlimeter reads the battery voltage when I connect the Positive lead to that cable on the Alternator and the ground to a strut tower bolt.
At this point I'm at a loss and could use some help. It must have something to do elsewhere with the 4P Connection on the alternator.
Any other ideas?
