I began having issues with my crx battery light flickering. Eventually, the light began to stay on and subsequently died one night. I replaced the alternator and took it for a test run and the light came back on. So today i bought a new battery and, yep you guessed it, the light came back on while driving. Any suggestions?

 

re-test alternator or test using other known working alternator,tighten alternator belt or add a capacitor if using a strong amp setup...!!!

 

No after-market stereo to speak of. anything other than tightening the alternator belt?

 

Have the new alternator tested its not uncommon for just bought alternators to be bad espcially if there remanufactured.

Yeah if you did buy a new alternator from Kragens/PepBoys/etc have them check it before you leave...this will save you the hassle of putting it on only to find it's not working. It happens more than you think since it's remanufactured instead of new. When this happend to me I bought a used one for cheap and took it in to get tested...worked so I slapped it in and was and have been good for years. Good luck.

 

This exact thing happens to me too. IM thinking its the main relay, it didn't click the three times its supposed to when I turned the key. If it was the alternator wouldnt the car not turn on after awhile due to a dead battery? Why dont you replace that main relay and see what happens.

 

Mmmmm not necessarily. If you have a good battery you can drive for a good little bit before it gives out especially if your not running alot of accessories and its a little 4cyl as well. But when the battery light comes on that means the voltage is too low normally caused by a bad alternator but what does the main relay do?

I read that the main relay should click three times when you turn the key. First when the check engine light comes on, then when it turns off, finally when yoiu turn the car on. I didnt get the second click. ONly after the car is hot.
Does your idle get funny as well?

 

Today we replaced the alternator belt as well.. So thats a new alterator, battery, and belt. When i took it for a test drive the battery light appeared and stayed on until i turned the car off.. Im starting to run out of ideas!

 

Nothing about the idle is evidently unusual.

 

Have you tried changing the main relay? When my battery light comes on my idle gets high.

 

make sure the grounds are clean and touch the chassis good. and look at the positive and negative connectors to the battery and clean/replace. also make sure the plug to the alternator isn't gunked up and is clean(they can from time to time get grim in the grooves). and the ground from the alternator is clean. if not try a new alternator. most of the time battery's r not the problem, although it is possible

 

Where'd you buy the alternator from?
Eli

 

did you figure out the problem?

 

check for voltage on the battery if it's charging.... you may have a loose connection to the battery light

 

check the tension on the belt. if it is too tight or too loose it will give you a whole heap of problems. too tight will cause a lot of stress on the bearing, premature wearing, and a low voltage output. hope this helps at all

 

I believe the alternator was the problem. I took out the refurbished alternator i purchased and replaced it for another and all is well again.

 

cool. im letting the car cool down before i swap the alt out. Then go and get my 40 bucks back.
