I have a 2000 civic si with about 145000 miles on it. The speedometer stopped working this morning. When I took my car to go to the gym the rpm's stopped working then the radio shut off. After I got to a stop light the car idled rough then died. Car will beep when keys in the ignition and my phone will charge but nothing else turns on. Never had problems with it before. Any suggestions.

 

Test the battery - charge or replace if necessary.

Clean battery connectors and the battery ground wire.

Check whether 7.5A fuse 15 is blown.

One engine starts, take car to an auto parts store to have the alternator tested.

battery, fuses, grounds, alternator...check in that order

 

When i jump started it, it ran fine for like 5 min. Im not sure if the speedometer worked but the rpm's did. After about 5 min it died again. I was thinking alternator but I'll test everything out. Thanks

 

I put a refurb alternator in and it started right up. only thing is the voltage didnt go up it stayed the same for 10 min then died again. Any ideas now?

 

Also when I unplugged the positive the car died. does that mean the refurd alternator was bad?

 

possibly but check all the fuses and voltages at battery and alt
