What could cause my 300 not to start when the battery is good?
Lights, radio comes on but will not crank. Usually have to jump it and it will start for a few days or hours. I took my battery to get it checked and was told it was good. Don't know what else it can be. I'm tired of charging it everyday to make sure I can get through the day.
Have you checked your alternators output voltage? It should be around 14 volts. If not have it tested and or replaced. How old is you battery? I had to replace the one in my 2007 dodge truck. It tested good but still had same issue as you. My alternator tested good to. I then just replaced the battery even though the tests said it was good. And no more issues since then.
check your key...This happened to me and I finally figured out what it was. You can see if your security light goes solid when the key is inserted. I had to start using my backup key
