My accord has a 3 year old alternator and the battery has been replaced three times counting the new one installed with the new alternator. It will jump start but dies as soon as the jumper cables are removed. Obviously the alternator is not taking over but that's about all I know. The alternator was checked with a meter and checked okay. Any ideas?

 

Well if the alternator checks out fine but it obviously isn't recharging the battery then your place to start is with the cables that come from the alternator. One of the probably has a poor connection.

I'll try that. Thanks!
As you can probably tell, I'm taking baby steps here so all input is welcome.

 

My d4 light is flashing on my 1992 honda accord. I replaced my main relay n my transmission control unit. The d4 is still flashing. When it is flashing you have to press the pedal to the floor to accelerate?? Any help

 

what is the voltage while running at the battery? MAke sure everything is off... head lights, wipers, rear defroster, blower motor all off..

 

Check for a current draw. You might have something sucking power when the car is off. Use a meter to measure current when the car is off. Put the meter in between the battery and ground cable. Are you buying good batteries or cheapo from walmart?

 

make sure your alternator fusse is not popped.


use a voltmeter touch the positive side of the battery and the main alternator wire. see what you got there.
