1998 honda civic lx keeps shutting down Sign In

Hey I have a 98' Honda Civic that has 3 alternators and it continues to shut off. I've got the last 2 alternators from the junk yard, so I don't know if maybe that is why. I bought the alternator about 2 weeks ago and my radio shuts on and off, then the speedometer goes crazy then the car just shuts off. I had the battery tested and it is fine. Could there be another problem why my car keeps shutting off?

I'm guessing the battery goes dead or way too low when this happens. That will kill most batteries alone and alternator needs a good battery to work. Charge battery if it will and look for what voltage you get with engine off and again with it running. If no change or ever seen lower than 12.2 or so volts off it's (battery) is in trouble. While running it should be able to maintain over 13 volts even with items running. Car seems to go dead from lack of charging - no spark no fuel as both are electrically driven.

Test the alternator(s) - the large outlets do that as a courtesy so you'll know it's good. Not sure your battery really is all that good and should test again or if older consider tossing that for new. Take a hard look at the cable connections too. They can corrode and not make a very good connection at all,
