I have a 95 civic that I have replace the alternator and the wire that goes from the alternator to the fuse box and the battery will not charge. The indicator light is not on but the circuit is fine. I have about 14.3 volts from the alternator bolt and the beginning of the wire, but when I get to the end of the wire at the fuse box I only have about 12.3 I also get 12.3 at the battery. Does anyone know what the problem is, because I have replaced an alternator that was tested outside of the car at the parts store and the store said the alternator is fine. When I tested the old alternator and the new one on the car the part store guys said that I had a bad regulator on both alternators.

 

Test for continuity and a short for the large wht wire that runs from the alternator to the hood fuse box.

 

I did that and it isn't open it has continuity also it doesn't have excessive resistance and to make sure that the alternator wire wasn't the problem I replaced it with a new good wire and I am still only getting 12.3 at the end of the alternator wire where it meets the fuse box using either wire.

 

Use a multimeter to check the wht wire for a short.

 

Well i replaced the wire itself with a new one to make sure the wire wasn't the problem.

 

Test for a short.

 

new battery?

 

lol, you beat me to it ^^

my battery just took a crap 2 weeks ago..

I went with a small Shuriken BT20 for 65 shipped as replacement.

 

Ooo. How's that working out for you? I'm looking at getting a new battery.

 

I found a thread on here where everyone says they like them and still going strong..

Even Chris@Xeno

did a google shopping search and 63.99 shipped later, its installed and working great so far

 

Check your chassis ground connections.
