I've got a 95 2.2L ex accord and I've been having some issues with it for a while, I've replaced the alternator, had it tested and it's tested good, replaced several damaged wires, replaced the negative battery cable, when testing the power output straight from the alternator it shows as less than what it should be, any help would be appreciated

 

What voltage measurememts are you getting?

 

Around sub 10 V

 

I'm not sure where you are putting your meter leads, so only having 10V to work from, the issue can be the alternator, the large + or -cables, mayby the ECU/alternator controls, and maybe a separated crank pulley/severly slipping belt.

Wiring is the quickest test. Put the red meter lead on the large + post of the alternator, then use the ground meter lead on the alternator housing, then the engine block, then negative cable from the battery where it bolts to the body, and then the - battery post. Let us know what voltage you get at each location with the engine running. Changing from 13 to <10 can locate a bad/poorly connected ground cable.

You can do a similar test where you keep the meter lead on the - battery post, then use the red meter lead on + battery post, then work your way to the alternator.

 

Will test that out later tonight when I have time, will lyk when Im done
