Electrical problems

i have a 96 dx with B16a, i was at a friends trying to fix my reverse light while messing with both sensors on the transmission using the test light (shouldnt of done that) after fixing the reverse light, started the car up check engine lights up with the code 25 blinking 2 times slow then 5 fast. Dont know the code 25 but 2 and 5 are the o2 sensor and map sensor then as i pulled out of the drive noticing that the speedometer didnt work, then after drving about 10-20 mins my car Radio dies, cluster starts to dim, headlights gone too,
o yea i had the car running couple of time to when seeing if the reverse light would come and testing the sensors too.
i had to shift down everytime i felt the throttle was not giving using only 1st to keep on moving of sudden the car dies. My friend gives me a jump car moving fine but same thing happens everything dims almost made it home. test the battery it was good. Alternator havent test. Anyone here with any idea what could be this mystery electronical problem before i waste to money taking my car back to hondata on something little. Now my car starts up fine but engine light still on and speedometer dont work but i took the car for a drive to see what would happen nothing happen with the light dim or any throttle feeling
Anything pleasssee! Thanks

o yea if anything comes to mind what year and model to order from? thanks again.

well n/m mind about the cut off come to find out it was the alternator sp senors fuse that took the check engine light off but while ridng aroound for 20 mins it came back on code 2,5,and 17 now.

u think by fixing the the speed sensor that code 2 and 5 would be fix because dont they run off each somehow with the ECu. Just a guess. Help!
