Last night my car started acting funny. When I was driving the lights started to dim out along with the lights in the interior. I have been running an odyssey mini battery for about four months with no problem. After I shut the car of it would not crank again. I had another mini battery in the garage (a buschur one) so I hooked that up and the car started again.

I then unconnected the positive terminal while the car was still running and it stayed on and did not shut off. I then turned the headlights on and it stayed running for a few seconds and then died. So does this mean the mini battery is just defective or could I have a problem with the alternator. It should die when I turn the lights on right?

 

I am fairly certain that the alternator in our cars is enough to power the car and the lights. If your car died then I think maybe your alternator maybe going.... Not 100% on this though.

 

easy diagnosis, take it to the local auto-zone/parts box store they can check the alternator while it's on the car....

 

Alternator has a problem.
The alternator should sustain the car without the battery connected.

 

alternator is bad.. see if you can find one off someone parting a car out or sumthin since they can be very expensive... good luck with it though..

 

damn and with only 4k miles on it!

 

I agree

 

I have a brand new Alternator that I got for my evo but didnt need cause it was just the fuse. Got it from dealership for 244$ have reciept and comes with warrenty I'll let it go cheap if you need one or for somthing i can use for my evo .

 

the same thing happen to me, its not the "Alternator", its only the fuse
check the main power line from your alternator to your battery (the one with 80amp fuse).....

 

this isnt true, that alternator in our car needed the battery to say alive, if you dont believe me, remove the battery and wait to see how long your motor stay on

 

alright im going to check this out tommorow I dont want to go to dealer and have them rape me for something I dont need thanks for the input guys...
