so Ive been having problems with the car not starting recently and I have been testing stuff to figure out what is going on. With the battery fully charged (13.5v with car turned off) and the ignition disabled, the car began to struggle cranking after about 10 seconds. When the car is running, I get 13.5v. I am thinking its a crap battery.

 

whats the voltage cranking would tell more

 

well I just had the battery tested at autozone, and it said it was good. Looked like the voltage under load never went below 9v ... must be a short somewhere or an intermittent alternator issue.

 

Why on earth are you cranking for 10 seconds?

 

I wanted to see how it would do under load for an extended period of time, I read something about doing that on a website I came across and figured it couldn't hurt to try it out.

 

I would think if you were cranking an engine for 10 seconds straight that it's somewhat normal that it would struggle...

 

its your starter selonoid going bad dude. trust me. replace that **** and you can stop push starting your car.

 

9V loaded is fubar

 

Ill have to give that a shot. I have been having a problem for a long time now where I have to turn the key 5 - 10 times before the starter catches ... otherwise it just clicks with no start.

Ya, I guess but autozone said the battery was good and I cant imagine that a battery that dies as quick as mine has been would pass. I suppose it could be on the fritz and barely passed the test.
