My 2005 Corolla will only start by jump. Afr Mechanic's Assistant: Will the headlights turn on? Is the battery fully charged? Yes, headlights, dash, and interior all come on. Turn th key, nothing happens. Battery is 5 yrs old, 12.3 volts with my volt meter. Had it. Had it check at Auto store, it's good. It's not the starter because it will start when jumped. Had the alternator tested also it's good. After jump start, let it idle (900l several minutes. I turn the headlights on, blower on high, rear defroster on, each time the engine rpm drops a tiny bit. Then I put in gear and drive . At stop, the rpm bottoms out and stalls. Turn the key, nothing happens. Mechanic's Assistant: Are you fixing your Corolla yourself? What have you tried so far? Yes, 8m trying to fix it. I'm assuming there's an issue withe the alternator wiring harness or the contacts. Not enough current is getting to the is being received which h causes it to stall after several minutes? Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Not that I can think of right now

Answer 1

Hi, my name is\*\*\*\*\* to justanswer. Lets see if we cant get you rolling again. So, it sounds like you have alot of the bases covered here. Have you tested your alternator output with your volt meter while revving the engine to 2000RPMs? **\*\*. During this conversation you will be given an automated offer for a phone call from justanswer, not me. You may accept or decline that offer. I don’t personally offer this service so if you take this another tech may call. Thank you\*\***

Answer 2

All these tests were done two months ago?

Answer 3

I would definitely check alternator output with your volt meter. It should read 13.8v or higher while revving engine. Although your battery is testing 12.3v it is at the end of its life span. Usually 4-6 years is an average life of a battery.

Answer 4

Okay, sounds good. Thanks for using justanswer, and good luck!

Answer 5

Have you been able to check for any trouble codes?

Answer 6

From the way you are explaining, it sounds like everything in the charging system is checking out. Now, you say it will start with jumper cables. Will it not crank at all before connecting the cables?

Answer 7

It is possible. I assume you have double checked your connector and battery cable at the back of the alternator?

Answer 8

No signs of excessive corrosion?

Answer 9

How about the battery connection at the alternator. Have you checked that for 12v? Not the connector, but the small cable that connects with a nut.

Answer 10

That cable goes directly to your battery. Should have 12v.

Answer 11

You are welcome. Happy Holidays.
