I'm not sure it's the battery directly. Also there is no graphic for the battery ameperage as the only graphic provided is for the starter (cranking). The guy said the amerpage of the battery would be lower since it is an older battery, but I didn't know the battery would have an effect on the lights directly when the car is running, I'd assume it would be the alternator. I'm almost positive the lights don't flicker when the car is turned off and they stay on for just a few minutes before shutting off automatically.


Does that still sound like the battery to you?


Also note the idle vs load amperage 14.86 idle 14.00 load?

 

As I said your battery voltage, cranking amps, are low, and as it is started, the voltage drops too low. That indicates the battery is on its last legs. Note one of the slips indicates it needs recharging, which can also indicate the battery needs replacement. You may well have two problems. I'd replace the battery and take it.from there.

 

Recharge the battery as advised, then check the starter again. Could be bad starter, bad battery, bad ground.

Those boxes look good, but are not always correct. Looks like a bad battery by the numbers, but maybe not.

 

Now that I see the video and the graph for the starter test, and the numbers for the results.
The battery is headed south , dying and not recharging, been there denied that, had to get new battery installed while on vacation, boy was my wife PO'd lost a few hours waiting for the AAA guy!

 

Out of curiosity, just how old is the battery?

 

I've had the car for three years and I have not replaced the battery

 

At best you have a battery at the end of it's warranty at worst you have a 10 year old battery (that was a 6 year battery).

 

Battery replaced problem still persistent.


Are there instructions on checking grounds prior to buying an alternator?

Old battery was 11/10 sticker date

Hey Steve. Problem with that link. All the pictures are not coming up. May be something to do with the sites recent overhaul.
