Corolla suddenly not starting, need diagnostic advice

Asked by Sep 08, 2015 at 06:27 PM about the 2010 Toyota Corolla S

Question type: Maintenance & Repair

Battery is less than a year old.  Put battery on charger, chargers says
battery is 100%, multi-meter shows 12+ volts too.  Interior lights come on
when door is open, horn works, radio will come on in accessory mode.  
When I turn the ignition on (not all of the way to start, just to ignition
position) dash lights come on for a second then go dark.  Whole electrical
system seems to die.  If I wait a couple of minutes, interior lights, horn, etc
start working again.  If I try to crank engine, same symptom, I do not hear
starter click at all.  Are there any basic things I can check before going to a
mechanic?

chech all the battery cables and the ground to engine/frame and motor...

1 out of 1 people think this is helpful.

Just wanted to follow up here. With my multi-meter I measured 6.5 ohms from negative terminal on battery to the alternator. Took off the battery/chassis and chassis/engine ground cables and polished the terminal ends with a dremel w/wire brush attachment. Polished chassis and engine where cables attach. After, measured only 0.1 ohms. Car turned right over and started. I was thinking this was a major problem way over my head to fix. Thank you Kelly!
