Default alternator fuse problem

hey guys, I run a H22a in a civic EK. I installed a new alternator a couple weeks ago, since then no problem. but yesterday my speedometer stop working, and I know alternator and speed sensor is on the same 7.5 fuse. it was blown.. I replace it and instantly it blow again.

replace it again and unplug the connector at the alternator and start the engine. the fuse did not blown. but as soon as I replug the alternator connector, it blown right away.

did some one ever had the same issue ?

There may be a short inside the alternator.

If you disconnect the large alternator wire but leave the 4P connector plugged in, does the fuse still blow?
